These ball bushings have the same boundary dimensions as the standard open ball bushings and are usually interchangeable.

super open linear bearings They offer the same advantage of self alignment as the closed type Super Ball Bushings. Because of an additional ball race in the larger size ball bushings, their carrying capacity is slightly increased. The bushing is provided with a retention hole to secure it against displacement.
