1. Full standard metric range：Complete model coverage from 31305 to 31320. Characterized by large contact angle, outstanding axial load capacity compared with ordinary tapered roller bearings.

2. High radial & axial combined load：Single‑row tapered roller structure. Takes heavy radial load and large one‑way axial load, great shock resistance for impact‑prone working conditions.

3. Separable assembly structure：Cone assembly and outer cup can be separated. Easy installation, disassembly and field inspection, frequently applied in paired back‑to‑back arrangement.

4. Robust material & consistent operation：Manufactured from premium bearing steel with precise heat‑treatment. Low friction, stable rotation, maintains good performance under continuous heavy‑load operation.

5. Typical heavy‑duty application scenarios：Mainly used for heavy‑duty gear units, mining equipment, construction machinery, vehicle drive axles and oil‑field machinery, metric size for global interchange.
