Reduce Friction in Machine-guard Doors
POSTED 12/20/2009
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.
