Double-row miniature linear recirculating ball bearings and guideway assemblies are full-complement, preloaded linear locating bearings for unlimited stroke lengths.

A unit comprises at least one carriage with a locating face and a guideway.

The units can absorb forces from all directions and moments around all axes, apart from the direction of motion. The double row units have two rows of rolling elements in four-point contact with the raceways. Guideways and carriages are also available in wide versions.
