This LM11949/LM11910 taper roller bearing is made of chrome steel, is unsealed, and has a steel cage. It has a 3/4" inside diameter, a 1.781" outside diameter, and a 0.655" depth. This single row taper roller bearing is suitable for applications that support both radial and axial loads. This bearing's inner and outer races are made of chrome steel for durability and resistance to deformity under heavy loads. This ball bearing conforms to ABEC 1 precision standard for performance within a narrow range of variation. This bearing is open for lubrication in place. A steel cage evenly spaces rollers for reduced friction, vibration, and noise. This bearing supports heavier loads than bearings with comparable-sized ball bearings.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
