Carries combined radial, axial and moment loads simultaneously through cylindrical rollers arranged crosswise at 90° to each other on a single raceway, allowing one unit to replace two separate bearings in the same mounting position. The XV90 has a net mass of 1.197 kg and does not feature gear teeth on the outer or inner ring. Lamellar seals are fitted on both sides of the bearing. The crossed roller arrangement gives high rigidity and accurate guidance under load reversals, since axial and radial clearances are set within the same raceway system without additional shims. The lamellar seals on both sides protect the rollers and raceways from contamination and retain the grease fill without contact-seal friction, which keeps running torque low and even. The absence of gear teeth means the XV90 requires external drive or clamping elements if rotary indexing is needed; the unit itself only provides the rolling support function.
