Features: RU Series Crossed roller bearing is Integrated Inner/Outer Ring type
Inner Diameter: 20-350mm Outer Diameter: 70-540mm Width: 12-45mm
RU crossed roller bearing can be used for both inner-ring rotation and outer-ring rotation
ince the mounting holes are provided, the model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque

(1) HRA series (two- -divided outer ring, rotation inner ring, ultra- -thin type)

This series is the compact HRB type of crossed cylindrical roller bearings with limit thickness of inner and outer rings. As HRB series, they have a two-divided outer ring, and are especially suitable for applications with weight reduction, compact design, and high rotation accuracy of inner ring, such as rotating portions of the robots.

(4) HRU series (integrated inner and outer rings, high rigidity, with mounting holes)

Because there are mounting holes on the outer and inner rings, the mounting flange and the support base are not required during mounting of these series of bearings. In addition, since the outer and inner rings are integrated structures, the mounting is virtually no impact on its performance, and the stable rotation accuracy and torque can be obtained. They are especially suitable for application with rotation of outer and inner rings.

Selection of crossed roller bearing

Crossed Roller Bearing RA

Notes in use of crossed roller bearings:

The two-divided imner or outer ring fixed with special rivets or bolts and nuts inseparable. and should be diectly mounted into the bearing base for use. Meanwhile. if the spacer holder assembling sequenceis improper ,it will have a great impact on the rotation performance of the bearing.so,the bearing can not be disassembled freely.There is some deviation athe joint of inner or outer ring, before it is mounted into the bearing seat.the bolts to fix the imner or outer ring should be loosened to correct it with a plastic hammer. (the fixed rivets may be deformed with the bearing base deformation)Do not apply any extermal force onto the fixed rivets orbolts during the mounting or removal.

Please note the size tolerances of the mounting parts, and press securely the inner or outer ring with the flange from the side.

Lubrication for crossed roller bearing:

The crossed roller bearing has been filled with high quality 2# lithium grease, so it can be directly mounted for use. However. compared with common roller bearings it has a smaller intemal space. so the grease must be replenished periodically.

The grease should be replenished from the grease hole connected to the grease groove on the outer and inner rings. The grease replenishment interval is generally 6-12 months. The same grease must be replenished in all areas

Meantime, when the grease is filled fully,the initial rotation torque will be increased in a short ime due to the grease resistance;when the excess grease is spilled from the seal portions,it will soon be retumed to the normal torque value.
