Linear Ball Bearings from the Precision Plus series are closed and self-aligning, featuring floating steel plates that allow the bearings to pivot within the housing and correct misalignment up to 1/2° in all directions. Hardened steel raceway inserts provide exceptional durability, complemented by a lightweight, high-strength polymer outer shell. With a low coefficient of friction, these bearings ensure smooth, high-speed operation. Available exclusively in inch sizes, they are fully interchangeable with industry-standard super-type linear ball bearings.
