RE25030 (Separable Inner Ring, Type for Outer Ring Rotation):This new model is based on the design of principal of the RB series, Having the same major dimensions as model RB series, its inner ring is separable while the outer ring is integrated with the main body, this model is used in locations where the rotation accuracy of the outer ring is required.

The inner and outer rings of  RE25030  , which are separable, are secured to Cross Roller Ring body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus, it is easy to handle the rings when installing the Cross Roller Ring. The spacer retainer keeps rollers in their proper position,there by preventing them from skewing.http://bycbearing.en.alibaba.com

and therefore secures a stable rotation torque. the cross array of rollers allows a single Cross Roller Ring  RE25030  unit to receive loads in all directions, increasing the rigidity to three to four times greater than the conventional type.

 Installation Procedure:

1.Thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required.

2.Since the Crossed Roller bearing is a thin-wall bearing type and therefore tends to misalign when it is installed, in case of this situation,gradually drive the product into the housing or onto the shaft by gently hitting it with a plastic hammer, while keeping the product horizontal. Taking care, continue to hammer until it fully contacts the reference surface.

3.Place the presser flange onto the Crossed Roller bearing . Rock the flange several times to match the bolt holes.

4.Insert the presser bolts into the holes.  Manually turn the bolts and make sure they do not display skewing caused by misalignment of the holes.

5. As is shown in the pictures below:Tighten the presser bolts in three to four steps from light to full tightening byrepeatedly securing the bolts in diagonal order.When tightening the separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body.
