The new hybrid bearing, DryLin® WJRM, was developed with the goal of reducing driving force. A self-lubricating plastic, sliding sleeve bearing ensures the hybrid linear system is dirt and moisture resistant, lightweight and low cost. A maintenance-free polymer roller brings ease of use to applications where heavy machine doors up to 110 pounds have to be adjusted manually. The unit is a flexible, modular linear guide system made from hard-anodized aluminum profiles, die-cast zinc housings, stainless steel or aluminum and plastic plain bearing materials. The wide variety of different combinations within this easy-to-install system allows users to optimize available design space. The linear guides work without lubrication as dry-running systems and do not require maintenance during operation.
