Linear module drylin® SHT series

Linear module with preload

SHT-PL - preload version
The axial preload reduces the backlash of the system. Positioning and repeatability can be optimised. The required drive torque increases only slightly.

Shaft materials

When using SHT linear modules, you can choose steel, stainless steel or hard anodised aluminium (standard) as a shaft material. The short delivery time and excellent coefficient of friction and wear make the aluminium version the most commonly used standard.

Lead screw materials and designs

All drylin® linear modules can be delivered with self-locking steel and stainless steel trapezoidal lead screws; upon request, they can also be made from hard coated aluminium. The SHT and SLW series can also be configured with stainless steel high helix lead screws.

The following steep threads are configurable: Ds20x5 / Ds20x10 / Ds20x20 / Ds20x50 / Ds20x60 / Ds20x50 / Ds20x50 / Ds20x60 
Ds20x80 and Ds20x90

Bearing materials

All drylin® drive units bearing points are equipped with lubrication-free­ and maintenance-free igus® high performance polymers. Options include materials for high-temperature applications up to +180°C (iglidur® X, SHT-ES series), and for FDA-compliant environments (iglidur® A180).
