For mounting of standard type SAMICK Linear Bushing into the Housing, a jig should be used to avoid direct hitting on the outer sleeve or seal when installing. See Below.
Care must be taken to allign the bushing and the shaft when inserting a shaft into a linear bushing. If the shaft is inserted with slanted, balls may depart from the damaged or deformed retainer.
Linear Bushing is not suitable for rotational motion.
If the Linear Bushing is exposed to rotainal motion it may lead unexpected accidents.
External loads should be distributed uniformly on a Linear Bushing. When moment loads are applied, two or more Linear Bushing should be used on one LM shaft, and the distance between two Linear Bushing should have enough distance. When the mooment loads are applied, calculate the equivalent load and choose the proper Linear Bushing.
Please mount the open type Linear Bushings with three ball circuit as same as Figure for considering of load distribution.
