KR40-PP-A Bolt Type Cam Needle Bearing 40x18x58 Mm high quality Textile machine bearing
1. With the purpose of increasing the load area effectively, this bearing is designed so that the radial gap is smaller than the general needle roller bearings. Therefore, it alleviates the impact load, and a stable longlife is gained. Since the stud undergoes screw processing and stepped processing, they can be attached easily.
2. Cam Followers come in series of abundant types such as those with cages, full complement, shield type, sealed type, spherical outer ring, cylindrical outer ring and ones with hexagon sockets.
