China Factory price export quality RAU18013/RA18013 Slim type crossed cylindrical roller bearings
Key attributes
Industry-specific attributes
Other attributes
In the RAU type crossed roller bearings, the rollers travel on the V-shaped raceways ground into the inner and outer rings. Alternating rollers are arrayed orthogonally so that one bearing can support loads and moments in any direction. Model RAU is more compact and lighter weight. Because of the integrated structure, the RAU can be used for either inner ring or outer ring rotation.
It is optimal for areas where the swiveling unit needs to be light and small. For example ,the rotational part of industrial robots or manipulator.
Features of RAU crossed roller bearings
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load:This series bearing can bear double-direction axial load, radial load and tilting moment
4. Small size: This series bearing can save space for machine tools
RAU crossed roller bearings application:
RA series crossed roller bearings are widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
