This Timken 15245 single cup matches with a single cone (inner ring assembly, sold separately) to assemble into a complete single tapered roller bearing, suitable for applications that support both radial and axial loads. It has a 2.441" outer diameter (OD) and a 0.5625" width. This cup is matched to its cone assembly based on the load that the bearing needs to support, and if the bearing needs radial internal clearance to accommodate thermal expansion. Generally mounted in opposing pairs on a shaft to evenly distribute loads, this single tapered roller bearing assembly is stable in temperatures ranging from -54 to 120 degrees C (-65 to 250 degrees F). The single cup is made of Timken's high-alloy steel for durability, heat tolerance, and resistance to deformity under heavy loads. As part of a separable tapered roller bearing unit, the single cup has an open design that allows for lubrication and accurate adjustments. This single tapered roller bearing conforms with the inch tolerance standards of the American Bearing Manufacturers Association (ABMA) standard 19.2, and 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 others.
Roller 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 roller 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.
Timken manufactures bearings, alloy steels, and related components and assemblies. The company, founded in 1890 and headquartered in Canton, OH, meets International Organization for Standardization (ISO) standards TS 16949 and 9001.
