Hybrid Linear Bearing reduces friction in machine guard doors.December 11, 2009 -
Combining rolling and sliding motions, DryLin® WJRM bearing is designed to reduce driving force in applications involving adjustment of machine-guard doors, partitions, and adjustable locks or light handling tasks. Self-lubricating, plastic sliding sleeve bearing ensures dirt and moisture resistance, while maintenance-free polymer roller enhances usability in applications where doors up to 110 lb have to be adjusted manually.

Reduce Friction in Machine Guard Doors
New hybrid linear bearing combines rolling and sliding
EAST PROVIDENCE, R.I. - The word 'hybrid' is used in engineering to describe a system where two technologies are combined together. igus® has now achieved this with a completely new type of cost-effective hybrid linear bearing that both rolls and slides.
The new hybrid bearing, DryLin® WJRM, was developed with the goal of reducing driving force, especially in applications involving the manual adjustment of machine-guard doors, partitions and adjustable locks, or for light handling tasks. For this purpose, igus took the advantages unique to sliding and rolling movements and combined them.
A self-lubricating plastic, sliding sleeve bearing ensures the hybrid linear system is robust, dirt and 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 pounds 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 new hybrid bearing is the latest extension to the tried-and-trusted DryLin W linear guide range from igus. The extremely compact system was modeled by igus' design engineers in such a way that the rollers fit inside the linear profile without increasing height, which remains at a low profile 0.71 inches (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 inches (40 mm) or 3.15 inches (80 mm). The hybrid bearing housing is made from blue-chromed die-cast zinc.
DryLin 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 extremely low wear and have a very low coefficient of friction. They are also chemical resistant, vibration dampening and absorb negligible amounts of moisture.
