L45449 interchange

L45449 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.

Mounting L45449 (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 L45449 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 L45449

FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating L45449/L45410 from the side takes about 3.58 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 50.29 × 14.22.

How FULI supplies L45449

L45449 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 (14.224 mm for L45449/L45410), 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 L45449/L45410.

Typical applications

  • Vehicle wheel hubs and axles
  • Gearboxes and reducers
