How to read the JL68145 designation
| Segment | Meaning |
|---|---|
| JL | Prefix JL: J-line, light series (J-line tapered roller bearing with metric boundary dimensions) |
| 68145 | Series and part number of the cone; the matching cup has its own number, listed in the pairs table on this page |
JL68145 interchange
JL68145 is a J-line tapered roller bearing cone with metric boundary dimensions, numbered like inch tapered bearings. Inch tapered roller bearings are ordered by cone number and cup number. Most makers use the same cone and cup numbers for the same size, but always check the cup number as well. Send us the numbers on your old bearing and we confirm the match before quoting.

JL68145 compared with nearby cone sizes
The JL68145 cone has a 35 mm (1.378 in) bore and a cone width of 18.461 mm. FULI's catalog pairs it with cup L68111 (59.974 mm outside diameter, 15.875 mm total width).
The next smaller cone on this site is L68149, with a 34.988 mm bore (0.01 mm smaller) and cup L68110.
The next larger is HM89449, with a 36.512 mm bore (1.51 mm larger) and cup HM89410.
The metric tapered bearing on this site closest in bore is 32007 (35 × 62 × 18 mm). Its sizes differ from the JL68145 pair, so the two are not interchangeable; it is given only as a size reference.

JL68145 load ratings
JL68145/L68111 has a dynamic load rating Cr of 34.9 kN and a static rating C0r of 46.9 kN in FULI's catalog. The ratings belong to the cone and cup as a pair; a different cup changes them.
Speed limits and weights for inch cones are not listed in the catalog; ask us and we send them with the quotation.

JL68145 size in inches and millimetres
JL68145 is a J-line number: the cone has a metric bore of 35 mm but is numbered in the inch system, so it is ordered by cone and cup number like an inch bearing. The cup it is listed with here, L68111, is 59.974 mm (2.361 in) outside diameter.
| Dimension | Millimetres | Inches |
|---|---|---|
| Cone bore d | 35 mm | 1.3780 in |
| Cup outside diameter D (L68111) | 59.974 mm | 2.3612 in |
| Total width T | 15.875 mm | 0.6250 in |
| Cone width B | 18.461 mm | 0.7268 in |
| Cup width C | 11.938 mm | 0.4700 in |
Converted at 1 in = 25.4 mm and rounded to four decimals.
Mounting JL68145 (general guidance)
General guidance, not a FULI specification: on a turning shaft the cone is a tight fit on the shaft and the cup a lighter fit in the housing, so the cup can be moved when the bearing pair is adjusted. Inch bearing fits are given as shaft and housing limits in inches in the bearing makers' tables; follow the drawing of your machine.
Tapered roller bearings carry radial load and axial load in one direction, so JL68145 is normally used as one of a pair, and the end play or preload is set at mounting.
If the outer ring turns and the shaft stands still, as in an idler pulley or a wheel hub, the fits are reversed: the housing gets the interference fit (for example N7 or P7) and the shaft a sliding one (g6 or h6).
Grease for JL68145
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating JL68145/L68111 from the side takes about 4.76 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 59.97 × 15.88.
How FULI supplies JL68145
JL68145 is supplied as a cone, as a cup or as a complete cone and cup pair, as your order states. Where an order states a requirement for the total width T (15.875 mm for JL68145/L68111), each set is checked on a height gauge before packing.
Rings are marked with a brand you are authorised to use, with the FULI brand, or left neutral, as your order states. The box is printed with the model, precision class and brand.
Inquiries that give only one number are the usual cause of a wrong quote, so write both the cone and the cup number, for example JL68145/L68111.

What is the difference between JL68145 and HM89449?
HM89449 has a 36.512 mm bore against 35 mm for JL68145, and pairs with cup HM89410 (36.512 × 76.2 × 29.37 mm) instead of L68111 (35 × 59.974 × 15.875 mm). The two are not interchangeable; order by the numbers on the old cone and cup.
How much grease does JL68145/L68111 need?
About 4.76 g each time it is relubricated from the side (0.005 × 59.97 × 15.88). FULI ships it rust-protected without grease, so the first fill is made at mounting.
Which cup goes with the JL68145 cone?
FULI's catalog pairs the JL68145 cone with cup L68111. Tell us whether you need the cone, the cup or both when you send the inquiry.
Is JL68145 the same size across brands?
JL68145 is a J-line tapered roller bearing cone number (metric boundary dimensions). Most makers use the same cone and cup numbers for the same size, but check the cup number too. Send us the numbers on your old bearing and we confirm the match.
