31330 150×320×72mm Heavy‑Thrust Taper Roller Bearing | Boyuan Mining & Heavy Machinery Bearing
31330 high‑angle tapered roller bearing belongs to large‑bore 313 series, designed for extreme heavy‑duty transmission positions with strong unidirectional axial thrust. Separable cone‑cup structure facilitates pre‑load setting, disassembly and maintenance work. High‑grade GCr15 bearing steel maintains stable performance under severe combined radial‑axial cyclic loads for OEM and global aftermarket spare‑part replacement.
