Crossed Roller Bearings RU297(G) RU297GUUCC0
stacker reclaimers bearing
RU297 crossed roller bearing achieves high rigidity and the accuracy can reach up to P2, P4, despite the minimum dimensions of the inner and outer rings, it is optimal for applications such as the industrial robot, rotation of the machining center, precision rotary worktable, medical machine, calculator, military industry, IC manufacturing devices, and other equipment.
RU297 crossed roller bearing features:
High stiffness. Integrated inner ring and outer ring to make the bearing have high stiffness than separated bearings.
Withstand radial, axial, and moment loads at the same time.
High rigidity & rotation accuracy, the compact structure reduces the influence of installation.
Optimization of preload, rigidity, high precision guide rollers running.
Significant savings in installation space. The inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts without need for housing and fixing plate, so surrounding parts of the bearing can be made compact, which contributes to miniaturization and a weight saving of devices.
Nylon spacer, low inertia, low starting torque, easy to control angle indexing
