GQZ HR32311J Single Row Tapered Roller Bearing 55×120×45.5mm ISO Standard Separate Cone & Cup Bearing

The HR32311J single row tapered roller bearing is designed for transmission and heavy vehicle equipment, adopting HR optimized roller layout and J standard ISO dimension design, separable cone and cup for independent installation.

It is widely used in automotive gearboxes, construction axles and mining machinery bearing mixed radial and single-direction axial thrust.

• HR optimized roller layout greatly improves dynamic and static load capacity
• Separable inner cone and outer cup allow separate assembly and clearance adjustment
• Medium steep contact angle bears heavy combined radial and one-way axial loads
• Stamped steel cage stable under shock, vibration and continuous heavy load
• Can be installed in pairs to withstand bidirectional axial force
• Custom design available (special clearance, anti-rust treatment, OEM laser marking)

This bearing is widely used in:

• Automotive drive axles, gearboxes and wheel hub assemblies
• Construction machinery, truck and heavy vehicle transmission parts
• Mining conveyors, crusher rotary shafts and metallurgical equipment
• Agricultural machinery gearboxes and heavy-duty industrial reducer units

• 25+ years experience in industrial bearing manufacturing
• Exported to 50+ countries worldwide
