Stepped or continuous – igus introduces new options for easy adjustments

By Marisa Martin | July 20, 2016

For manual adjustments, the motion plastics specialist igus has expanded its range of linear guides further and presents its novelties, such as the ball-pretensioned predefined positional system for stepped locking as well as the compact preload prism slide with pretensioned guide carriage. Depending on requirements, users can easily order their complete solutions for easy adjustments, rather than having to resort to own solutions or oversized linear guides. unnamed

‘Manual adjustment’ sounds like a very simple application, but it is often a major challenge. Especially when it comes to vertical adjustments such as kitchen equipment, headrests or fitness and rehabilitation equipment, in which the dead weight needs to bear light attachments. Here, recirculating ball guides are ruled out, because they are indeed very precise, but too expensive and cannot be held in place. They also require an external lubrication, which can lead to contamination of food or clothing. For such applications, the motion plastics specialist igus has developed various linear guides, which can be adjusted according to user requirements via defined locking points or continuously by adjustable pretension.

Firm hold guaranteed – lubrication-free pre-defined positional system
In the new drylin W stop motion pre-defined positional system, a plastic carriage moves on a profile and snaps into defined locking points. By means of a pretensioned ball between carriage and profile, which is held by a stainless steel spring, the carriage always stays in position and the dead weight also holds light attachments. The locking forces are dependent on the spring used as well as the bore, which like the rail length can be ordered for custom requirements. Due to the ball pretension in the plastic carriage, it sits on the lightweight aluminium profile virtually clearance free.

Very quiet continuous adjustment
The new drylin preload prism slide is also ideally suitable for manual adjustments wherever displacement forces and a “full” high quality run while moving are desired. Due to the four selectable spring pretension settings, the displacement force can be set individually. For light vertical loads, the carriage can be held in position easily. The guide rail is anodised and corrosion-resistant and can be ordered directly from igus up to three metres in length. The carriage of the preload prism slide is made of lubrication-free iglidur J, the springs are made of stainless steel, the mounting holes in the carriage made of brass.
