Preload Cross Roller Bearings

Preload cross roller bearings are units comprising inner and outer rings with a closing plug and securing dowel, rolling elements, spacers, contact seals and lubrication nipples.

--gear teeth on the outer ring, inner ring or without gear teeth.

--bearing rings with through holes or threaded holes for fixing screws.

Preload cross roller bearings can support high radial loads, moderate axial loads and tilting moment loads, can support higher dynamic loads than four point contact bearings

Preload cross roller bearings are used where zero operating clearance or preload is required, used in the rotational resistance must be particularly uniform, used in where there are high requirement for accuracy and rigidity of the bearing arrangement.
