Re15030, Thin Section Crossed Roller Bearing

Crossed roller bearings can withstand radial load, axial load and torque load, which is due to the special perpendicular arrangement of the isolation pieces and cylindrical rollers in a 900 V groove rolling surface. The miniaturization of inner and outer rings, thin form (closed to the limit small size), and the high rigidity make them most suitable for industrial robot joint and rotation, the turntable of machining center, mechanical rotary department, precision rotary worktable, medical machine, calculator, IC manufacturing equipment etc.
Rotating accuracy
Between the vertical rollers, there are equipped with isolation blocks, in order to prevent the tilt and friction between rollers, and reduce the running torque. In addition, compared with steel retainer used bearings, the edge of the roller stress concentration or deadlock phenomenon will never happen. At the same time, because the inner and outer rings are two integral structure, bearing clearance can be adjusted, even if being imposed to preload, they can also rotate smoothly.

Features:
1. High precision, precision can be P4, P2.
2. High rigidity: This series of bearing can preload.
3. High load: Can carry axial load, radial load and tipping load.
4. Small size: The bearing is small, save a lot of space for the host.
RA model has the same fission structure with the RB, making it the most suitable for light weight, compact design, such as the robot manipulator and rotating parts.
Application: Widely used in precision rotary worktable, mechanical rotary joint, medical apparatus and instruments, measuring instruments, etc.
