This Koyo YCR series yoke-type track roller bearing is unsealed and 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 bearings. The bearing is unsealed for use in environments where contaminants are not an issue. 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.

Track runner bearings, also called track roller bearings, are rolling element bearings with a thick-walled outer ring that rotates directly on cam and track surfaces. The thick outer ring helps minimize deformation under load stress and enables the bearing to handle heavy rolling and shock loads. Track runner bearings have either a stud-type or yoke-type mounting design. Stud-type track rollers, such as cam followers, have a built-in threaded rod, instead of an inner ring, for either threaded mounting or through-hole mounting onto machine components. Through-hole mounting uses a hexagonal nut on the threaded end to secure the bearing into place. Yoke-type track rollers, such as roller followers, are mounted in a yoke-style housing on a press-fitted or push-fitted shaft or pin. Available in a variety of materials and mounting configurations, track runner bearings are used in a broad range of cam-controlled and linear motion applications including agricultural machinery, conveying equipment, cam drives, material handling equipment, robotics, and automotive equipment, among others.
