Product Overview: The LM12749/711 Tapered Roller Bearing
The LM12749/711 is a single-row inch-series Tapered Roller Bearing, a crucial component for applications requiring support for combined radial and axial loads. With a bore diameter of 22mm, an outer diameter of 45.24mm, and a thickness of 15.50mm, this bearing is designed for precision and durability. It consists of a separable cone assembly (LM12749) and a cup (LM12711), which simplifies mounting and maintenance procedures. The tapered geometry of the rollers and raceways ensures that loads are distributed evenly, making it ideal for demanding environments where both types of forces are present.
As a key item in our Inch Tapered Roller Bearings collection, the LM12749/711 is manufactured to strict industry standards, ensuring reliable performance in various automotive and industrial machinery. Its robust design allows it to handle high loads and operate effectively, contributing to the longevity and efficiency of the equipment it's installed in.
