Find by measured dimensions
Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
6203 — published size and closure variants
6203 is the base grouping for the specific records below. Read the complete designation and publisher on each row. The source unit is retained beside the converted unit. A shield or seal can change the width; equal bore and outside diameter do not establish the same envelope.
3 source-labelled records; 3 shown initially.
| Publisher / full model | Closure / material | d×D×B in mm | d×D×B in inches | Source unit |
|---|---|---|---|---|
| SMB6203 | OpenChrome steel | 17× | 0.669291× | mm |
| SMB6203ZZ | ShieldedChrome steel | 17× | 0.669291× | mm |
| SMB6203-2RS | SealedChrome steel | 17× | 0.669291× | mm |
Keep RS, 2RS, ZZ and width suffixes distinct
The table records the publisher’s open, shielded or sealed column. An unlisted “RS” marking is not rewritten as “2RS”. Keep special endings such as W21, W23 or a fractional bore suffix: they can identify a different width or bore. No automatic cross-brand substitution is approved.
Metric values converted from printed inch decimals inherit the source rounding. For example, 0.2812 in converts to 7.14248 mm; that extra decimal detail is arithmetic, not a tolerance or a machining target. Never silently round an inch bearing into the nearest metric size. Missing speed, clearance, precision, internal ball diameter, material grade or exact lubricant remain unknown.
Publisher references: SMB product charts and Enduro 1600-series data; checked 2026-10-02. Original BearingScope interpretation. No stock, sales, vehicle fitment or redistributable CAD is implied. Material names describe the source page, not a certificate for every item sold under a similar number.
6203 — PEER catalogue dimensions
Independent technical reference from PEER’s historical 2009 sheets; checked 2026-10-03. These are catalogue records, not current-stock claims or replacement approvals. Printed units are kept separate.
| Full catalogue model | d×D×B (mm) | d×D×B (in) | Closed width / execution scope |
|---|---|---|---|
| PEER · 6200 series6203 | 17× | .6693× | Base designation only; complete closure execution must be checked |
Read ratings without transferring them to another execution
Cr and Cor are catalogue basic load ratings, not allowable application loads. Oil/grease values below are explicitly for open bearings where supplied. They are not sealed-bearing or machine operating-speed approvals. A dash means withheld or not established here.
| Model | Dynamic Cr / static Cor | Open: oil / grease | Evidence boundary |
|---|---|---|---|
| 6203 | 9600 / 4800 N | 21000 / 18000 r/min | Base-row catalogue values only; no cross-brand transfer. |
Printed decimal conversions inherit catalogue rounding; more decimal places do not create manufacturing accuracy. Special bores must not be rounded to a nearby metric bearing. The historical table does not establish an exact RS/2RS, NR, ABEC, C3, ceramic, vehicle or kit execution unless explicitly listed. No CAD or interchange approval is implied.
6203 — source-labelled NSK dimensions
Nominal dimensions from the NSK Bearing Replacement Guide, reference BRG/C/E/11.15. This is a historical catalogue reference, checked 2026-10-03; it is not a current product-availability list or an interchange approval. Each row preserves its complete printed designation.

Read d×D×B together. Equal outside dimensions do not prove equal seals, internal clearance, precision, load ratings, lubricant or speed limits. Those properties are not supplied by this dimensional table. A DU, DDU, Z, ZZ, VV, DD or other marking is kept as printed; missing suffix records are not created from a base model.
6203 dimensions and recorded technical data
The recorded 6203 base designation measures 17×40×12 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, NSK, KOYO, NACHI. It does not assign the same dimensions or operating ratings to every suffix.
The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 159 recorded variants are listed. A dash means the value is missing, not zero.

Boundary size alone does not describe every ring, shoulder or assembled unit. These tables retain the recorded manufacturer labels, symbols, units and limits for each complete marking. Expand a record to check its detailed measurements.
Important: an approximate value, a minimum or a maximum keeps that qualifier. These reference extracts are not CAD drawings, fit recommendations or replacement approvals.

Catalogue parameters for 6203
Choose the complete brand and marking before reading a value. These source-labelled records add dimensions, construction and engineering properties where they were recorded; a shared model number does not establish interchangeability.
Units, ranges and minimum/maximum qualifiers are retained. The data is a dated catalogue reference, not a certified drawing, a complete current specification or an operating approval.
SKF 6203 — 49 recorded parameters
Deep groove ball bearing
Reference: SKF product catalogue; source snapshot 2026-09-02.
SKF 6203 dimensional tolerances: the nominal bearing size is not the finished shaft or housing size. The following limits are calculated from this exact product record by adding the signed deviation to the nominal bearing dimension.
Bore mid-range size: nominal 17 mm; recorded deviation -0.007 to 0 mm; calculated interval 16.993–17.000 mm. Source symbol: t Δdmp.
Outside-diameter mid-range size: nominal 40 mm; recorded deviation -0.009 to 0 mm; calculated interval 39.991–40.000 mm. Source symbol: t ΔDmp.
Ring width: nominal 12 mm; recorded deviation -0.06 to 0 mm; calculated interval 11.940–12.000 mm. Source symbol: t ΔBs.
The source lists dimensional class "P6 and tighter width tolerance" and geometrical class "P5" separately. Do not collapse those two statements into one ABEC label or transfer them to another brand or suffix.
For cylindrical bores, the mid-range diameter is formed from the largest and smallest two-point sizes in a cross-section. Its allowable deviation is not a limit on every individual two-point measurement. Form variation and run-out are separate checks (SKF Rolling bearings, Table 13, printed pages 49–50).
A shaft/housing fit must be chosen separately for load direction, ring rotation, temperature and installation conditions. These bearing dimensions alone do not approve H7, k6, an interference fit, or an operating clearance.
Read the complete suffix and recorded construction. Similar dimensions do not prove identical seals, clearance, precision or material.
Values shown are retained from the recorded source. Zero boundary dimensions and zero load ratings from incomplete legacy feeds are withheld rather than presented as usable specifications.

Deep groove ball bearing
Reference: JTEKT / Koyo catalogue; source snapshot 2026-09-02.
The plain KOYO 6203 record is open. For a sealed candidate, inspect the separate KOYO 6203 2RS record; for a shielded candidate, inspect KOYO 6203 ZZ. Both are listed in this page’s exact-designation references with their own parameters. The base number alone does not specify a closure.
These are distinct catalogue constructions, not a suggestion to add a loose seal to an open bearing. Seal replacement or removal requires the original assembly information; no loose-seal part number or equipment fitment is established by these records.

KOYO 6203 2RS — 14 recorded parameters
Deep groove ball bearing
Reference: JTEKT / Koyo catalogue; source snapshot 2026-09-02.
Looking for a 6203 sealed bearing? KOYO 6203 2RS is a recorded catalogue candidate with contact seals on both sides. Its recorded nominal size is 17×40×12 mm, in the order bore d × outside diameter D × width B.
In JTEKT / KOYO Table 6-2, 2RS identifies contact seals on both sides. The corresponding one-sided code is RS. This manufacturer-specific explanation is consistent with the classification of this exact product record; it does not turn every 6203 base record into a sealed or shielded version.
Select the full marking, not the base number alone. Compare the grease-qualified speed, clearance, material and mounting dimensions of the candidate record before using it. A closure designation does not supply a waterproof rating, chemical-resistance certificate or approved replacement relationship.
The original product parameters below retain their source units. An absent or dash-valued oil speed is unknown, not zero and not permission to use the grease speed for an oil-lubricated arrangement.
Read the complete suffix and recorded construction. Similar dimensions do not prove identical seals, clearance, precision or material.
Values shown are retained from the recorded source. Zero boundary dimensions and zero load ratings from incomplete legacy feeds are withheld rather than presented as usable specifications.

NTN 6203LU — 20 recorded parameters
Single row deep groove ball bearings
Reference: NTN Europe public product catalogue; source snapshot 2026-10-02.
For this exact NTN 6203LU record, the nominal envelope is 17×40×12 mm (d = internal diameter; D = external diameter; B = bearing/inner ring width). These are bearing or washer dimensions, not shaft/housing fit limits.
Calculated inch equivalent: 0.669291×1.574803×0.472441 in, in the same axis order. The conversion uses exactly 25.4 mm per inch and rounds to six decimals; it is not an inch-series designation or a machining tolerance.
Recorded closure for 6203LU: contact seal on one side. Match the entire marking, including one-sided versus two-sided closure. A shared base number does not establish the same seal or shield across brands.
Use grease- and oil-qualified speed entries only for the named lubrication condition. Dynamic C and static C0 are catalogue ratings, not a universal safe load or installation approval; shoulder and fillet limits are separate from boundary size.

For this exact NSK 6203 record, the nominal envelope is 17×40×12 mm (d = bore diameter; D = outside diameter; B = bearing width). These are bearing or washer dimensions, not shaft/housing fit limits.
Calculated inch equivalent: 0.669291×1.574803×0.472441 in, in the same axis order. The conversion uses exactly 25.4 mm per inch and rounds to six decimals; it is not an inch-series designation or a machining tolerance.
Recorded closure for 6203: Open. Match the entire marking, including one-sided versus two-sided closure. A shared base number does not establish the same seal or shield across brands.
Use grease- and oil-qualified speed entries only for the named lubrication condition. Dynamic C and static C0 are catalogue ratings, not a universal safe load or installation approval; shoulder and fillet limits are separate from boundary size.

KOYO 6203 ZZ — 16 recorded parameters
Deep groove ball bearing
Reference: JTEKT / KOYO public product catalogue; source snapshot 2026-09-02.
Looking for a 6203 shielded bearing? KOYO 6203 ZZ is a recorded catalogue candidate with fixed shields on both sides. Its recorded nominal size is 17×40×12 mm, in the order bore d × outside diameter D × width B.
In JTEKT / KOYO Table 6-2, ZZ identifies fixed shields on both sides. The corresponding one-sided code is Z. This manufacturer-specific explanation is consistent with the classification of this exact product record; it does not turn every 6203 base record into a sealed or shielded version.
Select the full marking, not the base number alone. Compare the grease-qualified speed, clearance, material and mounting dimensions of the candidate record before using it. A closure designation does not supply a waterproof rating, chemical-resistance certificate or approved replacement relationship.
The original product parameters below retain their source units. An absent or dash-valued oil speed is unknown, not zero and not permission to use the grease speed for an oil-lubricated arrangement.

How to compare these values
- Use the displayed dimension names and original symbols. Housing length L, height H2 and flange width are not bearing outside diameter D. A catalogue width with an unverified symbol must not be assumed to be inner-ring width B or assembly width T. Open the product record for mounting dimensions and geometry.
- Inch values are calculated from the recorded millimetres using 25.4 mm per inch, rounded to six decimal places. They do not change a metric bearing into an inch-series bearing. Gram values are converted from the recorded mass in kilograms.
- C and C0 describe different rating conditions. They are not a single safe working-load limit and cannot replace an application load calculation.
- Reference and limiting speeds are separate catalogue values. The source grease/oil context is shown where recorded. Lubricant, seals, loads, fit, clearance and cooling affect the usable operating speed.
- A common base number does not prove equivalent seals, clearance, precision, material or interchangeability. Open the full designation for these fields.

Nominal dimensions are not shaft-fit tolerances. Different variants can add grooves, flanges, wider rings or assembly components. When the table has different dimensions, the complete designation—not the shared prefix—controls.
Reference basis & data limits
Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
Selection workflows and catalogue grouping are BearingScope editorial aids. Verify the current drawing and application requirements before using a candidate. Missing database information is not converted into an assumed match.
