Technical Characteristics - Precision combined bearings
Precision combined bearings have the same technical characteristics as fixed combined bearings and adjustable combined bearings with eccentric pin.
They are manufactured with a wider diameter than the standard ones, because they are used in machined profiles.
The very precise coupling between profile and bearing represents a very good and economic solution in comparison to linear guides.
These bearings are being used in alternative to the linear guides more often.
