UJK Spherical Roller Bearings are robust, high-capacity bearings designed to accommodate heavy radial loads, moderate axial loads, and shaft misalignment in demanding industrial environments. Featuring two rows of symmetrical barrel-shaped rollers and a common spherical raceway in the outer ring, these bearings are self-aligning and maintain performance even in the presence of shaft deflection or mounting misalignment.
Manufactured with high-quality bearing steel, precision raceway grinding, and advanced heat treatment, UJK spherical roller bearings ensure high load capacity, durability, and operational reliability in critical applications.
Self-aligning design compensates for shaft misalignment
High radial load capacity, withstanding shock and vibration
Can handle moderate axial loads in both directions
Available with cylindrical or tapered bore
Optional seals and lubrication holes for extended maintenance intervals
UJK spherical roller bearings are widely used in industries that demand long service life under heavy-duty and misaligned conditions, including:
Mining and Quarrying Equipment
Cement and Steel Mills
Gearboxes and Crushers
Pulp and Paper Processing Equipment
Heavy Trucks and Off-road Vehicles
Marine and Port Machinery
Agricultural and Construction Machinery
Mechanical Fans, Blowers, and Industrial Pumps
