RA5008UU Crossed Roller Bearing 50x66x8mm Thin Section Slewing Bearing Equivalent To CRBS508 Bearings High Stiffness

Features of RA5008UU Crossed Roller Bearings

1. Sustain radial, axial and moment loads at the same time. 2. Thin section, ultra-slim type crossed roller ring, can be mounted to limited space. 3. With separators, provide stable rotation and suited for high speed rotation. 4. One single bearing equals two common bearings, make the best use of space. 5. High rigidity & running accuracy supplied with normal clearance, little clearance or Even under a pre-load.

Lubrication and Maintenance of RA5008UU Bearing

All BRS bearing products are pre-lubricated before delivery except stated otherwise. So they can be immediately put into application under normal working conditions, without extra lubrication during operating. At the initial stage of running, bearings' friction torque will increase temporarily, and will become stable along with running, after grease evenly coated the raceway and rollers. Generally bearings need to be re-lubricated every 1-6 months, based on the specific working conditions.

Applications

RA series cross roller bearings are specially suitable for the applications where space is very limited, while high rigidity and high rotation accuracy are required. 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.
