RE4510UUCC0P5

RE type is two pieces Inner Ring Type for Rotation.
Having the same major dimensions as model RB, this model is usedin locations where the rotation accuracy of the outer ring is required.
This type cross roller bearing allows just one bearing to receive loads in all directions including radial, axial and moment loads.

High Rotation Accuracy
The spacer retainer fi tting among cross-arrayed rollers prevents rollers from skewing and the rotational
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 torque.
Easy Handling
The inner and outer rings, which are separable, are secured to the Cross-Roller Ring body after
being installed with rollers and spacer retainers in order to prevent the rings from separating from
each other. Thus, it is easy to handle the rings when installing the Cross-Roller Ring.
Skewing Prevention
The spacer retainer keeps rollers in their proper position, thereby preventing them from skewing
(tilted rollers). This eliminates friction between rollers, thus allowing the smooth motion to be
achieved.
Increased Rigidity
The rollers are arranged crosswise to the adjacent roller, so one bearing can receive the load in
each direction. It increases the rigidity to three to four times greater than the conventional type comparedwith the angular ball bearings installed in double rows.

RE series model is shaped by the RB generated new style design , the main dimensions and XRB same type . Its structure is split inner ring is the type ,the outer ring is the one designed for applications requiring high precision rotation of the outer parts.

With the Cross-Roller Ring, 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 despite the minimum possible dimensions of the innerand 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, medicalequipment, measuring instruments and IC manufacturing machines.
