Hybrid linear bearing combines rolling and sliding

The hybrid bearing DryLin WJRM was developed to reduce driving force, in particular that required for the manual adjustment of doors, guards, partitions and adjustable locks, as well as for light handling tasks. For this purpose the specific advantages of the sliding and rolling movements have been combined.

The lubricant-free plastic sliding plain bearings ensure the hybrid linear system is robust, insensitive to dirt and humidity, as well as light in weight and low in cost. The polymer rollers, which are also maintenance- free, bring ease of use where heavy machine and protective doors up to 50kg have to be adjusted by hand. At a defined installation position, the driving force required is reduced by a factor of 4 to 5, due to the roller bearing which bears the main load. This makes manual operation so much easier.

The DryLin W linear guid family is a flexible modular system made of hard anodized aluminium profiles, die cast zinc housings, fine-cast stainless steel or aluminium and plastic plain bearings. The wide variety of elements within this easy-to-install system allows users to optimise the available design space. Combined with different carriage lengths, the rail widths permit many combinations. The four design sizes range from 6mm to a shaft diameter of 20mm.

All the DryLin W guide systems work without lubricants as so-called dry-running systems, which means they do not have to be serviced during operation. The linear bearings are offered with the polymer sliding bearings iglidur J or iglidur J200. Both materials offer low wear and friction values. In addition, they are resistant to chemicals, dampen vibrations and hardly absorb any humidity.
