FR type is supplied as a set which would include a bush and a shaft. Constructed with combination of a load carrying outer cylinder and a load free ball recirculation cover, it is engineered to smoothly handle compound motions. For ease of mounting, the FRA type which has the FR bush pre-installed into a factory made housing is also available.
High load capacity & high rigidity
High load capacity, high rigidity, and long life are achieved through bearings place all around the inner space between an outer cylinder and a linear shaft.
Smooth motion
Although it is an all-ball bearing construction, load carrying bearings are designed to align along the linear movement to provide smooth motion in both linear and rotational directions.
High accuracy
Each set of a shaft and a bush is matched and controlled to ensure smooth and highly accurate motion.
