GQZ 32315-A Single Row Tapered Roller Bearing 75×160×58mm Separable Type For Heavy Load Transmission Shafts

32315-A is single row separable tapered roller bearing with optimized A-type internal geometry. Tapered contact surfaces between rollers and raceways can bear heavy radial load and unidirectional axial load simultaneously. Separable inner cone and outer cup simplify installation, disassembly and preload adjustment. It suits heavy-duty transmission systems working under impact vibration and mixed load conditions.

Formal quotation will be sent within 24 hours upon your inquiry.

Complete dimension drawings and load data available on request.

1. A optimized internal geometric structure improves contact matching, enhances load capacity and shock resistance
2. Tapered raceway structure bears radial force and one-way axial thrust load at the same time
3. Separable inner and outer components support independent fitting and flexible preload adjustment
4. Superfinished roller surface reduces friction heat and running noise during continuous operation
5. Standard metric dimensions, fully interchangeable with same specification tapered roller bearings
6. Customizable options: OEM laser marking, high temperature resistant grease, special clearance grades

Effectively reduce roller fatigue wear and extend service life of heavy machinery transmission assemblies.

• Truck, bus drive axles, differential and vehicle gearbox assemblies
