14276 bearing dimensions & suffix variants

TIMKEN 14276 — individual cup dimensions

TIMKEN 14276 is an individual tapered-roller cup (outer ring), not the complete cone-and-cup bearing. The manufacturer lists outside diameter D = 69.012 mm (2.7170 in) and outer-ring width C = 15.875 mm (0.625 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.

TIMKEN 14276 — bearing pairs and set identification

For TIMKEN 14276, the component number alone does not establish every dimension of a complete bearing. This reference identifies documented cone/cup combinations that contain 14276; select the row matching both of your component markings.

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.

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.
