July 19, 2016 - For manual adjustments, the motion plastics specialist igus has expanded its range of linear guides with the ball-pretensioned predefined positional system for stepped locking, as well as the preload prism slide with pretensioned guide carriage.
In the 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.
The 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.
