Compact rolling modules which, when combined with linear guideways, eliminate the problem of limited stroke and ensure high precision as well as uniform load distribution in all directions.
NRV preload wedge is used for setting preload at NRT recirculating unit. The NRV with its concave and convex supporting surfaces is also able to even out minor angular errors and defor mations in the connecting structure.
