IGUS of Germany has developed a variant of the DryLin W family of linear guides so that the modular system comprises anodised aluminium, die-cast zinc housings, and plastic plain bearings, to enable the best possible use of available installation space.
Distributed throughout Australia by Treotham Trading , the DryLin WQ has widths of the guide rail of 40mm and 80mm that allow many different combinations to be used with carriage lengths of 100mm, 150mm and 200mm.
As well as a new size 20 system designed for high loads, igus has introduced a new approach carriage design which fits onto the anodised aluminium double rails or flexible single rail. This new DryLin WQ type can now be used to better compensate the differences of height in the mounting faces.
A square-shaped design ensures - unlike the case with round shafts - that the loads are evenly distributed for better results. Due to a flat supporting surface, the friction value of the guide is reduced by 15% compared to the well-established DryLin W guide.
In addition, the friction value (-20%) and wear (-34%) is optimised by the use of a new plain bearing material (iglidur J200).
The overwhelming robustness of the new square-shaped solution sees large supporting surfaces distribute the load evenly and can therefore be used in applications which have a high surface pressure.
Due to the fact that the guide system works without lubricants - dry running - particles of dirt and dust are not attracted. This makes the guide system extremely insensitive to dirt and maintenance-free during normal operation.
Users are also able to reduce the installation costs with the DryLin WQ variant. Movable bearings in all directions (±1mm floating bearings) compensate the alignment and parallelism errors between the rails. Jamming, which is otherwise only to be prevented by the means of time-consuming alignment of the rails, can thus be ruled out.
