These combined bearings are manufactured according to the Unified Parameters that govern correct execution of rolling bearings.



The outer rings are normally scheduled in correct convex performance to counteract the inevitable geometrical errors originating from the coupling with the guide-ways in which they roll.



Bearings are greased at source with grade-3 lithium base grease. For special performance conditions such as the use of these bearings at high temperatures, please inquire with our engineering office.
