Interchangeable with conventional linear bushings, Power Linear Bush is engineered with cages made of synthetic resin that continually lubricates rolling elements. It exhibits smooth, quiet motion due to construction of ball retainer and outer sleeve. Convex shape of ball plate provides pivot point at center, allowing self-adjustment capability up to 0.5 deg that eliminates possibility of edge pressure caused by inaccurate machining, mounting errors, or shaft deflection.
