Product Description:

    Ball retainer linear bushings are accordingly based on Bronze, Aluminium, POM. Thay are machined some regular holes and embedded the steel ball. The new technology will prevent the ball getting out. As the ball diameter is larger than the retainer's thickness, the ball is out of the inner and outer surface of the retainer, the ball will face housing and shaft directly and keep the retainer hanging. And the ball diameter is more than the radii balance of housing and shaft, so it is over assembled but the motion between housing and shaft is very easy. This will keep high precision.
