Supporting roller bearing typically consists of four main components: 1. Machined thick-walled outer race; 2. Needle roller or cylindrical roller; 3. Retainer track; 4. Inner race, bolt, and seal.

Supporting Roller Bearings (NUTR series) feature roller elements instead of needles, guiding the supporting roller. They are of the full roller type. The Supporting Roller Bearings (NUTR series) have a compact structure and strong capabilities in radial and impact loads.
