WJRM drylin Hybrid Bearing

The hybrid bearing, DryLin WJRM, is a self-lubricating plastic, sliding sleeve bearing that ensures the hybrid linear system is robust, dirt & moisture-resistant, lightweight, and low-cost. Meanwhile, a maintenance-free polymer roller brings ease of use to applications where heavy machine doors up to 110 lb. (49.8 kg) have to be adjusted manually. The required driving force is reduced by a factor of 4 to 5 due to this roller bearing, which carries the main load. This makes manual operation much easier.

The hybrid bearing is the latest extension to the tried-and-trusted linear guide range from igus. The compact system allows the rollers to fit inside the linear profile without increasing height, which remains at a low profile of 0.71 in. (18 mm). Standard linear guide profiles can be used, which are available in three styles for shaft diameters of 0.39 (10 mm): as individual rails for more flexibility and as double rails for fast installation without time-consuming alignment. The latter comes with a distance between rails of 1.57 in. (40 mm) or 3.15 in. (80 mm).

The hybrid bearing housing is made from blue-chromed die-cast zinc. W 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. DryLin W linear guides work without lubrication as dry-running systems and do not require maintenance during operation. They use plastic liners made from iglide J or iglide J200, both of which are low wear and have a very low coefficient of friction. They are also chemical resistant, vibration dampening, and absorb negligible amounts of moisture.
