A good combination: New linear and pivot guide from igus

Drylin W linear guide with a PRT slewing ring bearing provides sliding and rotating adjustments.

Igus has developed the new drylin W linear and pivot guide for use in multifunctional armchairs and seats. It allows users to move trays or displays forward and backward linearly as well as to rotate them using a bearing.

Michael Hornung, drylin linear and drive technology product manager for igus, explained: “In addition to cinema, theatre and aircraft seats, the new drylin W guide is intended for applications in control cabins, such as in tractors or even on cranes. Wherever operating elements have to be moved flexibly and ergonomically in a compact space.”

For this new development, igus combined a drylin W linear guide for linear motion with a PRT-04 slewing ring bearing for rotation. The bearing is already integrated in the carriage plate. For the user, this previously meant that both products had to be laboriously installed together. The carriage plate had to be machined to accommodate the slewing ring bearing and the cable feed-through, and all components had to be fitted precisely Due to the directly coordinated and ready-to-install complete solution, the user will be able to save costs for assembly and rework.

Quiet adjustment
Instead of ball guides, igus uses tribologically optimised polymers in the sliding elements of the linear carriage and the bearing. They are up to four times quieter than ball guides, the company claimed, and at the same time lubrication0free and maintenance-free. By dispensing with additional lubricants and oils, the drylin W linear and pivot guide is insensitive to dust and dirt. Cleanliness is another advantage for the frequent use of the guide by different people.

Hornung added: “In addition to the practical functionality of our new product, we naturally also attached great importance to the design. Light materials such as plastic and aluminum are used. We use a decorative clear anodised coating for the rails.”

At 40mm, the new design study has a low-profile system height, and can also be equipped with a manual clamp and individual pretension. This way, the display stays in place after adjustment. The drylin W modular system further allows the product to be adjusted to any length.
