Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
6221 — 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.

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 |
|---|---|---|---|
| 6221 | 133000 / 105000 N | 4000 / 3400 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.
6221 dimensions and recorded technical data
The recorded 6221 base designation measures 105×190×36 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, FAG, NSK, KOYO. 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. 30 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.

Use the complete designation shown here. A seal, cage, clearance or precision suffix can matter even when nominal boundary dimensions match.
Minimum and maximum mounting dimensions are limits, not nominal bearing dimensions. Check shaft/housing shoulders and fillets against the current drawing before designing a seat.

Metric and inch measurements below are the values published together in this dated manufacturer record. Their displayed rounding is retained; the inch column does not turn a metric design into an inch-series design.
Keep the full marking shown for this record. Equal nominal dimensions do not establish matching closure, clearance, precision, material or operating limits.
Shaft and housing backing-shoulder dimensions, maximum fillet radii and signed offsets answer different installation questions. Preserve the named face, limit and sign; they are not additional bearing outside diameters or nominal widths.
This factual extract is a dimensional reference, not an OEM fitment statement, a replacement approval or a downloadable CAD model.

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.
Related prefix matches — other model numbers may appear
These discovery results can contain a longer number or a different component. They are not specifications for the requested exact model. Open the complete product to inspect its original geometry.

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.
