RB1250110UU-CC0-P4 Cross Roller Bearings
The RB1250110 bearing is a Slewing Bearing with an inner diameter of 1250 mm , an outer diameter of 1500 mm, a width of 110 mm. It typically uses P0/P6/P5/P4/P2 grade precision tolerances and NONE/UU/U type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
LYHJ Crossed Roller Bearings consist mainly of an outer ring, an inner ring and a plurality of rollers
And spacers.
1.Structure and Features
With the Cross-Roller Ring, cylindrical rollers are arranged with each roller perpendicular to the ad-
Jacent 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 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.
2.High Rotation Accuracy
The spacer retainer Fitting among cross-arrayed rollers prevents rollers from skewing and the rota-
Tional torque from increasing due to friction between rollers. Unlike conventional types using steel
Sheet retainers, the Cross-Roller Ring does not cause unilateral contact of roller or seize. Thus,
Even under a preload, the Cross-Roller Ring provides stable rotation.
Since the inner and outer rings are designed to be separable, the preload can be adjusted, and this
Feature enables accurate rotation.
3.RB/CRBA/CRBC Series
TSplit outer ring type
Consists of an inner ring and two outer semi-rings, which is suitable for inner ring rotation.
