1. Standard 4T integrated assembly, great interchangeability for vehicle aftermarket and industrial machinery
2. Tapered raceway structure withstands 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. Precision superfinished roller surface lowers friction heat and running noise during continuous operation
5. Compact structure saves mounting space for mechanical design with limited installation room
6. Customizable options: OEM laser marking, high temperature grease, special clearance grades Effectively reduce roller fatigue wear and prolong service life of transmission assemblies.

• Automobile wheel hubs, drive axles and differential assemblies
• Medium-sized construction machinery rotary transmission components
• Agricultural machinery gearboxes and power output drive shafts
• Medium-duty industrial reducers and conveyor roller supporting parts
• General mechanical equipment with combined radial and one-way axial load requirements
