Exact model answer539 / 532: cone, cup and complete bearing dimensions
TIMKEN 539 / 532 identifies the cone 539 and cup 532 in the manufacturer record. The matched pair has bore d = 53.975 mm, outside diameter D = 111.125 mm and assembled width T = 38.103 mm. These are measurements for that complete cone-and-cup combination.
Do not confuse the assembled width with a separate ring: cone width B is 36.957 mm, while cup width C is 33.338 mm. Read T directly from the matched-pair record; adding B and C does not give the assembled width.

What to check on your bearing
- Read the complete cone and cup markings. This record requires 539 together with 532; a similar-looking suffix or an extra prefix must be checked separately.
- For size identification, distinguish the shaft-side bore d, housing-side diameter D and assembled width T. For an unassembled ring, compare B or C with the corresponding row instead.
- Check the named front/back face before using a shoulder diameter or cage offset. Minimum and maximum qualifiers remain part of the measurement.
- Use the equipment procedure and the exact bearing specification to determine fits, adjustment, lubrication and operating limits. These nominal dimensions do not supply preload, end play or tightening torque.
Some optional mounting entries have metric and inch figures that do not reconcile at their displayed precision: Max Shaft Fillet Radius, Housing Backing Shoulder Dia. - Frontface (Da). Both numeric versions are withheld in this supplement. Verify the current manufacturer drawing before using those particular limits.
This is a dated dimensional reference, not a replacement approval or a manufacturer-certified drawing. Similar dimensions do not establish matching geometry, load capability, clearance, material or operating limits.
Useful model distinctions
- TIMKEN 535 / 532 — The listed cup is also 532, but its cone is 535 and its bore is 44.450 mm. A common cup does not make the complete assemblies identical.
