31308 40×90×25.25mm High‑Axial‑Load Taper Roller Bearing | Boyuan Industrial Transmission Bearing
313 series adopts steep contact angle design, providing much higher axial load capacity than standard 302 and 322 series. 31308 is a medium‑size high‑thrust tapered roller bearing for transmission positions bearing obvious one‑sided axial force. Separable cone‑cup enables easy pre‑load adjustment, disassembly and field maintenance. Made of GCr15 bearing steel, it performs well under combined radial‑axial cyclic loads for OEM assembly and aftermarket spare parts.
