Crossed roller bearings

Cross roller bearings are a type of rolling bearing in which the rolling elements are arranged perpendicular to each other so that, within a compact housing, they transmit loads in multiple directions simultaneously. The design arrangement allows distribution of radial, axial and moment components of the load into a single mounting space.

Characteristic properties of cross roller bearings are high stiffness, precise guidance of rotating parts and the ability to operate with limited installation space. Due to their geometry, the bearings behave stably under combined loading and can reduce play in axis positioning.

Structurally, cross roller bearings differ in the guidance of the rolling elements, the use of cages or groove guidance, and the method of assembly into machine assemblies. The selection of a suitable design is determined by the combination of operating conditions and the mechanical requirements of the system.

• High stiffness and accurate positioning
• Ability to transmit combined loads
• Compact design suitable for integrated applications
