The recirculating unit type SR has rollers arranged crosswise and is suitable for medium to high loads. In combination with SCHNEEBERGER type R and/or RD linear guideways, space-saving designs can be achieved that can be loaded in all directions. The type NRT roller bearing, and guideway assembly recirculating unit can also be used for medium to heavy loads. The NRVpreload wedge with its concave and convex supporting surfaces of the type NRV can even compensate for minor angular errors and deformations in the connecting structure
