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

Supporting roller bearings (NUTR series) feature rollers instead of needles for guidance, classifying them as full roller types. The structure of the supporting roller bearings (NUTR series) is compact, with high radial load and impact load capacity.
