BRS High Rigidity Cross Roller Bearing THK RU series(with Mounting Holes)
RU crossed roller bearing has a compact inner/outer ring, so it can provide high stiffness and high rotation accuracy. And with mounting holes on the inner and outer ring, RU face-mount cross roller rings’ installation does not require a presser flange or housing. It’s suitable for both inner-ring rotation and outer-ring rotation applications.
RU Series Crossed Roller Ring Features
1. Sustain radial, axial, and moment loads at the same time.
2. High rigidity & running accuracy, being less subject to the mounting procedure. Bearings precision can reach P5/P4/P2 and even USP grade.
3. Space-saving. As face mount crossed roller bearing, RU series bearings can be bolted onto the equipment without housing or fixing plates.
4. Custom design cross roller bearing is also available. BRS can produce face-mount crossed roller bearing with a bore diameter from 10mm to 350mm.
