TIMKEN 02420 — individual cup dimensions
TIMKEN 02420 is an individual tapered-roller cup (outer ring), not the complete cone-and-cup bearing. The manufacturer lists outside diameter D = 68.263 mm (2.6875 in) and outer-ring width C = 17.463 mm (0.6875 in).
| Measurement | Symbol | Metric | Inches |
|---|---|---|---|
| O.D. (D) | D | 68.263 mm | 2.6875 in |
| Outer Ring Width (C) | C | 17.463 mm | 0.6875 in |
| Max Housing Fillet Radius | Not specified | 1.52 mm | 0.06 in |
| Housing Backing Shoulder Dia. - Backface (Db) | Db | 58.93 mm | 2.32 in |
Use the component number correctly
- D is the nominal cup outside diameter. C measures this outer ring only; it is not the assembled bearing width T. This single-cup record does not establish a shaft bore d or a matching cone.
- Preserve the full component number and its suffix. A shared prefix, similar ring size or a related-products suggestion does not approve a cone/cup combination or a cross-brand replacement.
- For a complete bearing, check both component markings and the manufacturer’s assembled d×D×T record. B+C is not a valid way to calculate T. A seal, axle rating, vehicle application and tightening procedure need their own evidence.
- Optional measurements with inconsistent printed metric and inch values are omitted from this supplement: Housing Backing Shoulder Dia. - Frontface (Da). Verify the manufacturer drawing before using these particular limits.

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.
Check the drawing before substituting
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.
