Recirculating ball bearing guides are often made with heavy metal. With drylin® linear bearings made of high-performance plastics, overall weight is very low. Most drylin® linear systems use guide rails made of anodized aluminum, coupled with the plastic sliding elements, which guarantees low mass for easy handling. The use of plastics also reduces energy consumption and emissions, lowers transportation costs and reduces moments of inertia for high-acceleration applications.
