Exact model answerSET45: cone, cup and complete bearing dimensions
TIMKEN SET45 identifies the cone LM501349 and cup LM501310 in the manufacturer record. The matched pair has bore d = 41.275 mm, outside diameter D = 73.431 mm and assembled width T = 19.558 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 19.812 mm, while cup width C is 14.732 mm. Read T directly from the matched-pair record; adding B and C does not give the assembled width.
The SET designation is the lookup name in the manufacturer feed; the dimensional catalogue identifies the components as LM501349 / LM501310. This connection establishes the listed component geometry, not identical packaging, a matching UPC, a supplied seal or an approved vehicle application.

What to check on your bearing
- Read the complete cone and cup markings. This record requires LM501349 together with LM501310; 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.
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 SET47 — Its outer diameter and assembled width match this record, but its bore is 45.242 mm and its component pair is different. Equal D and T are not an interchange approval.
