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).
