cross roller bearings p2 precision for industrial robots machine tools rotary tables, medical equipment, measuring instruments

with the cross-roller ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90v 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 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, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and ic manufacturing machines.

since each cross-roller ring unit contains high-quality germanic grease imported, you can start using the product without replenishing grease. however, the product requires regular lubrication since it has a smaller internal space than ordinary roller bearings and because the rollers need frequent lubrication due to their rolling contact structure. to replenish grease, it is necessary to secure greasing holes that lead to the oil grooves formed on the inner and outer rings. as for the lubrication interval, normally replenish grease of the same group so that it is distributed throughout the interior of the bearing at least every six to twelve months. when the bearing is filled up with grease, the initial rotation torque temporarily increases. however, surplus grease will run off of the seals and the torque will return to the normal level in a short period. the thin type does not have an oil groove. secure an oil groove inside the housing for lubrication.

the separable inner or outer ring is fastened in place using special rivets, bolts or nuts when delivered. when installing it to the system, do not disassemble it. also, erroneously installing the spacer retainer will significantly affect the rotational performance of the system. do not disassemble the bearing.

1、the matching mark of the inner or outer ring may be slightly misaligned when delivered. in that case, loosen the bolts that secure the inner or outer ring, and correct the alignment using a plastic hammer or the like, before installing it to the housing .

2、when installing or removing the cross-roller ring, do not apply force to the securing rivets or the bolts.

3、when mounting the presser flange, take into account the dimensional tolerances of the parts so that the flange firmly holds the inner and outer ring from the side.

installation procedure
when installing the cross-roller ring, follow the procedure below.
1、checking the parts before installing them thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required.
2、installing the cross-roller ring into the housing or onto the shaft since the cross-roller ring is a thin-wall bearing type and therefore tends to misalign when it is installed, 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、attaching the presser flange
(1) place the presser flange onto the cross-roller ring. rock the flange several times to match the bolt holes.
(2) 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.
(3) 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.
