Features

• The roller follower has a structure in which a needle roller is incorporated into a thick outer ring. It is a bearing designed for outer ring rotation with a low friction coefficient and excellent rotational performance.
• The outer ring outer diameter surface is in direct contact with the mating gum guide surface to guide the bearing. However, this bearing is designed with a small radial clearance to effectively increase the load range. This reduces the impact load and provides a stable and long life.
• Excellent in high-speed rotation with the combined structure of outer ring, inner ring and needle cage. In addition, since they can be separated, they are easy to handle. There are RNAST without inner ring and NAST with inner ring.
