About Koyo CRSB-8 Track Roller, Standard Stud, Sealed/Hex
This Koyo steel stud-type track roller bearing with a hexagonal hole 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, and a hexagonal hole on the flange end that provides greater holding power during mounting than a screwdriver slot. This track roller is made of bearing steel treated with black oxide for corrosion protection, and holds a full complement of needle rollers for a higher radial load-carrying capacity than caged rollers. Lip seals on both sides of the bearing retain grease applied at manufacture and help protect against contaminants, and internal thrust washers made of self-lubricating resin help reduce sliding friction. Its operating temperatures range from -30 to +110 degrees C. Depending on size, inch series track rollers with a hexagonal socket can be lubricated through the threaded end of the stud using a standard nominal inch drive-type grease lubrication fitting, through a cross-drilled hole in the shank, or through the hexagonal socket on the stud head. (Sizes 8 to 10.1 inches cannot be relubricated.) 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.Specifications Sizes 8–10.1 No grease hole Size 12 and larger Relubrication through the thre
