All Precision heavy-duty U-joints are machined to meet or exceed original equipment specifications. All parts are precision-ground to stringent tolerances with quality-control inspections at every step of the manufacturing process.

Precision heavy-duty U-joints offer the following features:

• Cold-formed bearing cups, case-hardened using state-of-the-art manufacturing processes
• Grease fitting holes that are drilled and tapped
• Cross trunnions that have large grease reservoirs for optimal grease distribution
• Internal anti-drain-back valves to control lubrication flow and prevent dry start-up
• Heat-treated needle bearings made from the highest-quality steer
• High-quality, long-wearing, abrasion-resistant nitrile seals that extend the life of the U-joint by retaining bearing lubricants and keeping out contaminants
• Exclusive thrust washer design that includes radial lubrication and an anti-drain-back feature. Available on popular medium- and heavy-duty U-joints as well as power takeoff (PTO) U-joints.
