Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
TIMKEN SET415 — bearing pairs and set identification
TIMKEN SET415 identifies a bearing package. The 2024-05 manufacturer listing pairs cone HM518445 with cup HM518410. Keep both full markings when checking the assembly.

Complete bearing dimensions by exact pair
These TS single-row tapered-roller combinations are reproduced as factual measurements from the 2002 reference. Dimensions are not a fitment approval or a current availability claim. Each cell keeps both published units.
| Cone / cup | Bore d | Outside D | Assembly T |
|---|---|---|---|
| HM518445 / HM518410 | 88.900 mm 3.500 in | 152.400 mm 6.000 in | 39.688 mm 1.563 in |
Separate ring widths B / C and source page references
B and C below describe separate components. Their sum is not the assembly width T.

What to confirm before using this reference
- d is the cone bore, D is the cup outside diameter and T is the complete bearing width for the exact pair. B and C measure the separate rings; do not add B and C to calculate T.
- The dimensional table is a historical identification reference from the 2002 Timken Bearing Specification Guide, not a current engineering drawing. Printed metric and inch values are retained, including their original rounding. Check the current drawing before specifying fits or machining.
- A component may appear with several mating numbers. A match here documents that exact Timken combination; it does not approve other suffixes, mixed-brand rings, a vehicle application or a substitute with similar dimensions.
- A cone-and-cup set is not automatically a complete wheel-end repair kit. Seal numbers, collars, spacers and quantities must be confirmed separately unless the specific set note below explicitly lists them.
- For replacement work, inspect and replace the mating cup and cone together as specified for the assembly. Retaining a worn ring or mixing manufacturer geometries can change the contact pattern even when nominal diameters match.
- An axle tightening torque, preload or endplay target cannot be derived from these dimensions. Use the procedure for the identified hub or machine, including any pre-adjusted system restrictions.

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.
