CCTY Bearing's Square Ball Universal Joint includes only six components: 1 square ball, 2 yokes, 2 retaining pins and 1 seal.
CCTY Bearing uses a square ball and five other components for the Square Ball Universal Joint. This new u-joint features: 1 square ball, 2 yokes, 2 retaining pins and 1 seal. Fewer parts simplify the u-joint allowing for smoother rotation and stronger design, and typically means a reduction in cost. The patent-pending u-joint is maintenance-free due to a true seal that retains lubrication while keeping out containments. The Square Ball seeks its own center between the two yokes when it is rotating through an angle with some load. Rotational torque is transferred/concentrated around the left and right opposing zones of the yoke’s ID to the adjacent cylindrical surfaces of the Square Ball central element, not the center of the yoke or the grooves in the Square Ball. Constant velocity can be achieved when assembled with two properly phased and equal-angled joints.
