Product Overview: The LM300849/11 Tapered Roller Bearing
The LM300849/11 is a single-row inch series Tapered Roller Bearing designed for high performance in a wide range of industrial and automotive applications. With key dimensions of a 45.242mm bore diameter, a 77.788mm outer diameter, and a total width of 22.146mm, this bearing is engineered to handle a combination of radial and axial loads simultaneously. Its design consists of two main separable parts: the inner ring with rollers and cage (cone) and the outer ring (cup), which allows for easier mounting, dismounting, and maintenance. The tapered geometry of the rollers and raceways ensures true rolling motion, minimizing friction and wear for extended service life.
As a leading supplier of mechanical parts, we ensure our LM300849/11 bearings meet stringent industry standards for reliability and durability. This bearing is a crucial component in systems requiring robust support for rotating shafts under heavy load conditions.
