This Koyo Torrington YCR series yoke-type track roller bearing is suitable for supporting high static and dynamic loads in track-type applications. The yoke-type design is appropriate for heavier loads or where clevis or shaft mounting is preferred. A thick-walled outer ring helps minimize deformation under heavy radial and shock loads. This track roller has a full complement of needle bearings for higher radial load capacity than caged rollers. The roller is unsealed for applications in which contamination is not a factor. This track roller is suitable for use in a broad range of linear and motion translation applications including process transfer lines, ram support rollers, conveyors, machine tools, and indexing equipment.
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.
Koyo Bearings USA manufactures bearings, bearing assemblies, and needle rollers for automotive and industrial applications. The company, founded in 2009 and headquartered in Canton, OH, meets International Organization for Standardization Technical Specification (ISO/TS) standard 16949 and ISO standard 14001.
