Cam follower bearing is a kind of roller bearing with a special structure. One end of the bearing is a roller follower with a full complement of needle rollers, and the other end is a bolt with a nut. Its advantages are very obvious. One end with a nut is fixed on the mechanical equipment, and the other end drives the equipment to run without worry. The cam rollers not only carry a heavier axial load but also has good impact resistance. However, due to the full complement of needle roller bearings, it is necessary to frequently replenish the lubricant. Due to the different structures of the roller cam follower, there are many series of cam followers. For example, the NUKR series, NUKRE series, KR series, CF series, etc. We will have detailed drawing instructions for different models.
