Industrial KR52PP Cam Follower Needle Roller Bearing

The KR52PP Cam Follower Bearing (DR4F2) from SKF/INA is a stud-type needle roller bearing engineered for cam drives, conveyor systems, linear guides, and material handling equipment. It features a thick-walled outer ring, an integral M20x1.5 threaded stud with hex socket, and double lip seals (PP) to deliver high radial load capacity, low friction, and long service life in dirty or high-cycle applications. With a 20 mm bore, 52 mm outside diameter, 24 mm roller width, and 66 mm overall length, this bearing fits compact installations while providing smooth rolling motion under demanding loads. It is factory grease lubricated and designed for threaded-stud mounting, simplifying installation in automated production lines. Performance specifications include a dynamic load rating of 16.6 kN (3,619 lbf) and a static load rating of 28.0 kN (6,295 lbf), with a maximum speed of 2,800 RPM. Typical uses encompass conveyor systems, cam mechanisms, transfer equipment, packaging machinery, and other linear motion or automated equipment. Weight is approximately 0.46 kg (1.01 lb).
