RA series crossed roller bearings (outer ring division type with inner rotating, thin section) .This model is a compact type of model RB series crossed roller bearings with extremely thin outer and inner rings. 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. HONBbearing07

In the RAU, 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. Also, because of the integrated structure, the RAU can be used for either inner ring or outer ring rotation./

The RAU is more compact and lighter weight than a double row angular contact ball bearing. It is also more rigid, even though it is made as compact as possible.

Crossed Roller Bearing characteristics:

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
APPLICATION:
RA series crossed roller bearings are widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
