The micro-size Cross-Roller Ring RAU features a 10mm inner diameter and a 21mm outer diameter. It is more compact, lightweight and rigid than a double row angular contact ball bearing type. RAU rollers travel on 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. Spacer retainers enable smooth movement and high rotation accuracy.
