The combined bearings are manufactured according to the Unified Parameters which govern a correct execution of rolling bearings.
This series can be supplied with screened and they can therefore be re-lubricated and in the sealed performance. 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 with grade "3" lithium base grease. For special performances, as the use of these bearings at high temperatures, please inquire our engineering office.
