Crossed Roller Bearing RB7013
Features of crossed roller bearings
With the Cross Roller Bearing,cylindrical rollers are arranged crosswise,with each roller perpendicular to the adjacent roller,in a 90°V groove,separated from each other by a spacer retainer.This design allows just one bearing to receive loads in all directions including,radial,axial and moment loads.Since the Cross-Roller Ring achieves high rigidity and the precision can reach up to P5,P4,P2,despite the minimum possible dimensions of the inner and outer rings ,it is optimal for applications such as joints and swiveling units of industrial robots,swiveling tables of machining centers,medical,equipment,measuring instruments and IC manufacturing machines.
Rotation accuracy:
The spacer retainer fitting among cross-arrayed rollers from skewing and rotation torque from increasing due to friction between rollers.Unlike conventional types using steel sheet retainers,the Cross Roller Bearing does not cause displacement or locking of rollers and provides a stable rotation torque.Since the inner and outer rings are designed to be separable,the bearing clearance can be adjusted.In addition,highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.
Usage characteristics:
The inner and outer rings,which are separable,are secured to the Cross Roller Bearing 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 Bearing.The spacer retainer keeps rollers in their proper position,thereby preventing them from skewing.This eliminates friction between rollers,and therefore secures a stable rotation torque.The cross array of rollers allows a single Cross Roller Bearing 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 Cross-Roller Ring 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 Crossing-Roller Ring.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 no display skewing caused by misalignment of the holes.
5. As is shown in the figure1:
Tighten the presser bolts in three to four steps from light to full tightening by repeatedly 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.
