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

Supporting Roller Bearings (NUTR series) feature roller elements instead of needles, which guide the supporting rollers. They belong to the full roller type. The Supporting Roller Bearings (NUTR series) have a tight structure and can bear significant radial and impact loads.
