Our factory is mainly specialized in ball retainer linear motion bearing unit, with bronze retainer, aluminum retainer or pom plastic retainer. Most size of the ball retainer bearing unit will be available from us. You will be rest assured of the quality and the service from us.Other dimensions not listed in the table can also be provided, please send us your drawings or samples. We can also supply special thin wall thickness ball retainer linear motion bearing / bushing.Brief introductionFzh, fzl, fzp. Ball retainer linear bushings are accordingly based on bronze, aluminium, pom. They are machined some regular holes and embedded the steel ball. The new technology (circle groove) 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.Advantages and applicationThe traditional technology has some clearance between housing and shaft, the coefficient of friction is big. Now we use steel ball retainer and don`t keep the housing and shaft contact directly, so the precision is approved, rolling friction replace sliding friction, this struction has small friction coefficient, long service life, may roll or make linear movement. If use oilless bushing, but the precision is lower. If use ball bearing, this will make the linear motion impossible. It composes the advantage of both rotation and linear motion. So ball retainer bushing is the best when the linear motion and rotation motion both required. It is widely used in punching machine, die machine, high precision machine which needs rotation and linear motion.Installed parts required1.
