Product Details

Product Description

This Timken JP12049 single cone with a stamped steel cage matches with a single cup (outer ring, sold separately) to assemble into a complete single tapered roller bearing, suitable for applications that support both radial and axial loads. The cone assembly does not contract or expand under operating temperatures ranging from -54 to 120 degrees C (-65 to 250 degrees F). Generally mounted in opposing pairs on a shaft to evenly distribute loads, this single cone is made of Timken's own high-alloy steel for durability, heat tolerance, and resistance to deformity under heavy loads. The stamped steel cage prevents rollers from coming into contact with each other during use, reducing friction, vibration, and noise. As part of a separable tapered roller bearing unit, this single cone assembly has an open design that allows for lubrication and accurate adjustments. This single tapered roller bearing is for use in high-load, moderate-speed applications that include automotive axle systems and conveyor systems in heavy duty industries such as mining, construction and agriculture, among many other applications.

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.

The Timken Company manufactures a variety of bearings, alloy steels, and related components and assemblies that meet International Organization for Standardization (ISO) standards for quality assurance. Founded in 1899, the Timken Company is based in Canton, Ohio.
