SKF
Universal Joint Bearings
Universal joint bearings from SKF are needle roller bearings specifically designed for the trunnions of universal joints in driveshafts. They withstand oscillating motion under high loads, combined with centrifugal forces at high speeds. SKF offers these as complete kits including bearing cups (outer race), needle roller and cage assemblies, and seals. They are engineered for the heavy torque demands of industrial and automotive drivelines, rolling mill drives, and agricultural PTO shafts. The needle rollers are crowned to reduce edge stress, and the cup diameter is hardened to resist pounding. Effective sealing prevents grease loss and contamination ingress, critical for reliable operation in dirty environments. SKF’s robust design ensures consistent torque transmission with minimal backlash over long service intervals.

High Torque Capacity
Robust needle complements handle heavy drive loads.
Oscillation-Optimized
Designed for reciprocating angular motion, not continuous rotation.
Integral Sealing
Multi-lip seals retain grease and block contaminants.
Crowned Needles
Reduce edge stress in cup, enhancing fatigue life.
Ready-to-Assemble Kits
Includes bearing cup, needles, cage, seal, simplifying replacement.
Wide Size Range
Fits standard universal joint crosses from small drives to large mill couplings.
Universal Joint Bearing Replacement: Signs and Best Practices
Excessive backlash, vibration, or grease ejection signals bearing wear. SKF recommends measured preload during installation to minimize play. Correct greasing with EP grease through the joint’s central nipple ensures lubrication reaches all four trunnions, replenishing the bearing packs.
Industrial Applications of Universal Joint Needle Bearings
Steel rolling mill spindles, paper machine drive shafts, and heavy construction equipment all employ universal joints with SKF bearings. The ability to transmit torque at varying angles and high shock loads makes them indispensable for mobile and heavy machinery.
