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).
