Product Description

Product Overview: UJK Thrust Spherical Roller Bearing

Engineered for Heavy Axial Loads and Self-Alignment
The UJK Thrust Spherical Roller Bearing is a high-capacity axial bearing designed to accommodate heavy unidirectional thrust loads while compensating for shaft misalignment. Combining a spherical housing washer and asymmetrical barrel rollers, it delivers superior performance in applications requiring high axial rigidity, shock resistance, and operational reliability under misaligned conditions3.

 

Key Features & Benefits

 Self-Aligning Capability

• Compensates for ±2-3° misalignment via spherical housing washer raceway3.

• Prevents edge loading and premature failure in bent shafts or uneven housings.

 Exceptional Load Capacity

• Asymmetrical barrel rollers optimize stress distribution.

• Handles axial loads 30-50% higher than standard thrust ball bearings.

 UJK Performance Enhancements

• Premium bearing steel (HRC 60-64 hardness) with advanced heat treatment.

• Machined brass cages for high-speed stability (up to 1,500 rpm)3.

• Optimized roller profiles reduce friction and extend L10 fatigue life.

 Robust Design Options

• Open design: For centralized lubrication systems.

• Sealed variants (2RS): Integrated rubber seals for contaminated environments.

• Tapered bore options: For adapter sleeve mounting (suffix K).
