Exact model answerSET17: cone, cup and complete bearing dimensions
TIMKEN SET17 identifies the cone L68149 and cup L68111 in the manufacturer record. The matched pair has bore d = 34.989 mm, outside diameter D = 59.974 mm and assembled width T = 15.875 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 16.764 mm, while cup width C is 11.938 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 L68149 / L68111. 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 L68149 together with L68111; 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: 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.
