Universal Group says both products use a true spherical ball with a permanently lubricated, assembled seat engineered to withstand high frequency oscillation and high impact shocks. The ball joint design provides wide angulation with high load bearing capacity, along with great rotation capacity and conical angle.
Additionally, a patented polyurethane ball joint seal protects the ball joint from abrasive dust, salt, and moisture, and resists aging due to oxidation. The seal, permanently attached to the rod by a steel ring shrunk into place, will not tear or expand if punctured, the company adds.
