This INA NUKR series steel stud-type cam follower bearing with labyrinth seals and cylindrical rollers is designed for cam- and track-type applications, and supports high radial loads and axial loads resulting from slight misalignments. It has a thick-walled outer ring that helps minimize deformation under heavy radial and shock loads, and a contoured outer surface that helps evenly distribute loads when misalignments occur. This cam follower has a threaded stud-type design for through-hole or threaded mounting, and a hexagonal hole on the flange end that provides greater holding power during mounting than a screwdriver slot. This cam follower holds a full complement of cylindrical rollers for a higher radial load-carrying capacity than caged rollers. The cylindrical rollers and ribs provide axial guidance to the outer ring. Labyrinth seals on both sides of the bearing retain a lithium complex soap grease lubricant applied at manufacture and help protect against contaminants .The cam follower is made of low alloy, through-hardened chromium steel for durability and heat tolerance, and has lubrication holes on the stud’s flange side and thread-side end face for reapplying lubricant. It includes loose drive-fit lubrication nipples. Operating temperatures range from -30 to +140 degrees C. This cam follower 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.
INA manufactures bearings for automotive and industrial applications. The company is part of the Schaeffler Group, founded in 1946 in Herzogenaurach, Germany, and meets International Organization for Standardization (ISO) standards 9001:2008 and TS 16949:2009 for quality assurance.
