Technical Characteristics
Precision combined bearings
Precision combined bearings maintain the same characteristics as the previous series. 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.
