31308 Single Row High‑Angle Tapered Roller Bearing
31308 belongs to high‑angle 313 tapered roller bearing series, optimized for locations with prominent unidirectional axial force. Separable cone‑cup design facilitates pre‑load tuning, disassembly and on‑site service. High‑quality GCr15 steel resists fatigue under combined radial‑axial loads, fits original equipment assembly and replacement spare parts.
