This Koyo Torrington steel stud-type track roller bearing with a screwdriver slot and lip seals handles moderate radial and shock loads in cam- and track-type applications. This track roller bearing, also called a cam follower, has a thick-walled outer ring that helps minimize deformation under heavy radial and shock loads. It has a non-separable, threaded stud-type design for through-hole or threaded mounting, a screwdriver slot on the flange end that helps keep the stud from turning while tightening the mounting nut, and a full complement of needle rollers for a higher radial load-carrying capacity than caged rollers. This track roller is made of bearing steel treated with black oxide for corrosion protection. Its operating temperatures range from -30 to +110 degrees C. All inch-series stud-type track rollers with a screwdriver slot can be relubricated through the flanged end of the stud. Sizes 12 and larger can also be relubricated through the threaded end of the stud and through a cross-drilled hole in the stud shank. Both stud ends accept a standard nominal inch drive-type grease lubrication fitting (not included). All Stud-type track rollers come with lubrication fitting plugs for closing off unused holes. This track roller bearing meets American National Standards Institute/American Bearing Manufacturers Association (ANSI/ABMA) standard 18.2 for quality assurance and is suitable for use in a broad range of applications including process transfer lines, ram support rollers, conveyors, machine tools, and indexing equipment, among others.
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.
