Protection spiral for helical screw
Hennig
* Telescopic springs made of hardened high-grade spring steel ensure an excellent protection against dirt, swarf and mechanical damage even when fully extended
* Minimum overlap (of the individual windings) of 40%
* A special manufacturing method and optimal resilience ensure an easy compression and extension. Horizontal springs have a minimal sag and vertically used springs only a slight lateral deviation
* Winding-on types are available up to the size 54/1120/120
* Easy assembly by pushing the springs over the machine parts
