NUKR-47 Cam Follower Needle Roller Bearing NUKR47

Descriptions of NUKR series cam follower bearings 

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.

Genernal information of NUKR47 Cam follower bearing

NUKR47 Stud Type Track Rollers are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. These bearings have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.

The outer ring running surface is crowned as standard. This is beneficial for applications where angular misalignment relative to the track may occur or where edge stresses need to be minimized. With the exception of single row cam rollers, NUKR47 Stud Type Track Rollers are also available with a cylindrical (flat) outer ring running surface.
