Needle roller bearings have a long track record as proven machine elements for the design of radially compact bearing arrangements with very high load-carrying capacity. In X-life configuration, they now have an up to 50 % longer service life.
RUE linear recirculating roller bearing and guideway assemblies are, due to the cylindrical rollers, the INA monorail guidance systems with the highest load-carrying capacity and rigidity. They comprise at least one carriage with a full complement roller system, a guideway, integral elastic wipers on end faces of the carriage, sealing strips on the upper side and underside of the carriage and closing plugs to close off the fixing holes in the guideway.
The carriage and guideway of a linear recirculating roller bearing and guideway assembly are matched to each other due to their closely toleranced preload. It may be possible, after consultation, to use carriages and guideways in different combinations.
