TIMKEN 382-S — individual cup dimensions
TIMKEN 382-S is an individual tapered-roller cup (outer ring), not the complete cone-and-cup bearing. The manufacturer lists outside diameter D = 96.838 mm (3.8125 in) and outer-ring width C = 20.274 mm (0.7982 in).

| O.D. (D) | D | 96.838 mm | 3.8125 in |
| Outer Ring Width (C) | C | 20.274 mm | 0.7982 in |
| Max Housing Fillet Radius | Not specified | 2.29 mm | 0.090 in |
| Housing Backing Shoulder Dia. - Frontface (Da) | Da | 91.90 mm | 3.62 in |
| Housing Backing Shoulder Dia. - Backface (Db) | Db | 87.12 mm | 3.43 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.

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.
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.
