drylin SHT linear module in hygienic design
As part of our design study, we were looking for an ideal solution for the food industry, which we can now offer as a finished product. The linear axis uses drylin R stainless steel round shafts EWMS (material 1.4571 AISI 316 Ti) for the guide and the dryspin threaded spindle made of stainless steel (DS18x4) for the drive. All components, whether metal or plastic, were adapted to the same hygienic design specifications. The traverse assembly consists of two housing halves. The housing halves are sealed using a flat seal (FDA-compliant silicone seal) and screwed together using 8 hygienic screws per housing half to guarantee tightness.

Crossbars
The crossbars can be fixed to the application environment via two holes. We recommend using hygienic screws and nuts during assembly and sealing the holes completely.

Shaft and spindle sealing
The rotating spindle and shafts are sealed using specially configured wiper or radial shaft seals. The seals prevent dirt from entering the crosshead. There is a sufficiently large gap between the crosshead and spindle to prevent dirt from being deposited.

Linear slide with thread
Manufactured with FDA-compliant igus polymer in a patented design. Generous flushing grooves prevent nucleation between the thread and the threaded nut. The slide is guided on the shafts by FDA-compliant igus sliding bushes. The base body is made of highly resistant stainless steel (1.4571). A threaded nut made of FDA-compliant igus polymer is attached to the slide with hygienic screws and a silicone flat gasket. The patented threaded nut has generous flushing grooves that prevent the formation of germs between the thread and the threaded nut. The slide was designed with defined radii (min. R3) for a simple cleaning process. We also recommend the use of hygienic screw connections for the connection via the through-holes (left and right outside).
