L68149 interchange
L68149 is an inch tapered roller bearing cone. 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.

L68149 size in inches and millimetres
L68149 is made to inch sizes. The 34.988 mm bore is 1.3775 in; the nearest common fraction is 1-3/8 in (34.93 mm). The millimetre values in the catalog are conversions of the inch sizes.
| Dimension | Millimetres | Inches |
|---|---|---|
| Cone bore d | 34.988 mm | 1.3775 in |
| Cup outside diameter D (L68110) | 59.131 mm | 2.3280 in |
| Total width T | 15.875 mm | 0.6250 in |
| Cone width B | 16.764 mm | 0.6600 in |
| Cup width C | 11.938 mm | 0.4700 in |
Converted at 1 in = 25.4 mm and rounded to four decimals.
Mounting L68149 (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 L68149 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 L68149
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating L68149/L68110 from the side takes about 4.69 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 59.13 × 15.88.
How FULI supplies L68149
L68149 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 L68149/L68110), 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 L68149/L68110.
