6301 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with 6301. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

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.
6301 — published size and closure variants
6301 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 |
|---|---|---|---|---|
| SMB6301 | OpenChrome steel | 12× | 0.472441× | mm |
| SMB6301ZZ | ShieldedChrome steel | 12× | 0.472441× | mm |
| SMB6301-2RS | SealedChrome steel | 12× | 0.472441× | 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.
6301 dimensions and recorded technical data
The recorded 6301 base designation measures 12×37×12 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, NSK, KOYO, NACHI, NTN. 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. 73 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.

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.
