LM501349 interchange
LM501349 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.

LM501349 size in inches and millimetres
LM501349 is made to inch sizes. The 41.275 mm bore is 1-5/8 in. The millimetre values in the catalog are conversions of the inch sizes.
| Dimension | Millimetres | Inches |
|---|---|---|
| Cone bore d | 41.275 mm | 1.6250 in |
| Cup outside diameter D (LM501310) | 73.431 mm | 2.8910 in |
| Total width T | 19.558 mm | 0.7700 in |
| Cone width B | 19.812 mm | 0.7800 in |
| Cup width C | 14.732 mm | 0.5800 in |
Converted at 1 in = 25.4 mm and rounded to four decimals.
Mounting LM501349 (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 LM501349 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 LM501349
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating LM501349/LM501310 from the side takes about 7.18 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 73.43 × 19.56.
How FULI supplies LM501349
LM501349 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 (19.558 mm for LM501349/LM501310), 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 LM501349/LM501310.

FAQ
What size is LM501349 in mm?
The LM501349 cone has a 41.275 mm bore (1.625 in). With cup LM501310 the bearing is 41.275 × 73.431 × 19.558 mm (d × D × T). With cup LM501314 it is 73.431 mm outside diameter and 21.43 mm wide.
What is the difference between LM501349 and 25580?
25580 has a 44.45 mm bore against 41.275 mm for LM501349, and pairs with cup 25520 (44.45 × 82.931 × 23.8 mm) instead of LM501310 (41.275 × 73.431 × 19.558 mm). The two are not interchangeable; order by the numbers on the old cone and cup.
How much grease does LM501349/LM501310 need?
About 7.18 g each time it is relubricated from the side (0.005 × 73.43 × 19.56). FULI ships it rust-protected without grease, so the first fill is made at mounting.
Which cup goes with the LM501349 cone?
FULI's catalog pairs the LM501349 cone with cups LM501310 and LM501314. Tell us whether you need the cone, the cup or both when you send the inquiry.
Is LM501349 the same size across brands?
LM501349 is an inch tapered roller bearing cone number. 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.
