SPN SCHWABEN PRÄZISION FRITZ HOPF GMBH
SPN worm gears are manufactured single-stage as well as with preceding spur gear stage in foot and flange design. The low-backlash worm gears are also inserted in non-stop operation and cycle operation in tool and packaging machines.
Optimal material combinations and coordinated toothing geometry guarantees a high smooth running and best synchronization.
SPN worm gears are available with

SPN designs and produces linear actuators especially according to customer requirements.
We are able to react to special mechanical workload as well as special wishes in the electronical field.
The compact linear drive unit consists of a permanently excited synchron linear motor with high dynamic and minimum irreversibilities.
The drive has a solution of 5 μm and a continuous force of 13 N (Fmax = 430 N) at a power loss of 87 W, available for a travel length up to 0,80 m.
