Linear bearings drylin® R

Linear bearings an alternative to recirculating ball bearings

drylin® R linear bearings are based on extremely wear-resistant plastic sliding elements. As drylin® R linear bearings have the same dimensions as conventional standard ball bearings, a 1:1 replacement is possible without problems. The special shape permits use even in extreme environments. One of the key benefits of the sliding elements is the ease in replacing them and with a large range of materials available, they can be applied in various applications and environments.
