GEMO shafts need protection and guidance

GEMO protective casings combine a metal spiral with plastic or rubber or also an additional woven insert. They protect GEMO shafts from environmental influences such as dust, dirt and moisture and also offer improved guidance. Additional benefits of using a casing, which we recommend from a shaft length of 100 mm, are quieter operation and less twisting.

The casings are abrasion and temperature resistant and also resistant to many acids and lyes. The standard colour is black, with other colours available for bulk orders. 

As a rule of thumb, the inner casing diameter should be 1/3 larger than the shaft diameter.
