UJK Spherical Roller Bearings: High-Capacity Performance for Demanding & Misaligned Applications
UJK Spherical Roller Bearings are engineered to deliver exceptional durability and reliable performance in the toughest industrial environments. Designed specifically to handle heavy radial loads, moderate axial loads, and significant shaft misalignment, these bearings are the robust solution where high load capacity and operational resilience are critical.
Key Features & Advantages:
Exceptional Load Capacity: Features a double row of symmetrical, barrel-shaped rollers and a common spherical outer ring raceway. This design enables outstanding radial load handling and bidirectional axial load capacity-far exceeding that of self-aligning ball bearings.
Superior Misalignment Compensation: Inherently self-aligning, accommodating static and dynamic misalignment (±1.5° to ±2.5° typically) between shaft and housing. This protects against edge loading, reduces vibration, and extends service life in applications prone to shaft deflection or housing inaccuracies.
Optimized Stress Distribution: The curved profile of the rollers and spherical outer raceway promotes optimal load distribution across the rollers, minimizing stress concentrations and enhancing fatigue life.
Robust Construction & Reliability: Manufactured from high-purity, through-hardened bearing steel with advanced heat treatment. Precision grinding ensures smooth operation, high wear resistance, and resilience against shock loads and contaminants (especially with reinforced cage designs).
Versatile Cage Options: Available with pressed steel cages (standard) or machined brass/steel cages for higher speeds, temperatures, or harsh environments.
Low Friction & High Efficiency: Optimized internal geometry and premium lubrication compatibility reduce friction, lower operating temperatures, and improve energy efficiency.
Long Service Life & Reduced Downtime: Engineered for maximum operational reliability and extended maintenance intervals, lowering total cost of ownership.
Typical Applications:
Heavy-Duty Gearboxes & Industrial Gear Units
Mining & Mineral Processing Equipment (Crushers, Screens, Conveyors)
Material Handling Systems (Cranes, Hoists, Bulk Handling)
Pulp & Paper Machinery (Rolls, Refiners)
Fans, Blowers & Large Ventilation Systems
Pumps & Compressors
Construction & Agricultural Machinery
Marine & Offshore Equipment
