The linear actuators SCVA series, work in a range between 7.500 and 100.000 N with speed from 2 to 16mm/sec.
These are built with a worm screw reducer, made of high quality material: spheroidal ferritic cast iron reducer case, hardened and tempered steel worm screw, special bronze helical crown; carbon steel threaded rod. Ball and conical roller bearings to support motion. Grease or oil lubrication.
The SCVA linear actuators are available in the following executions:
- back cover with eye
A supplementary gearbox can be applied to all types whenever lower speeds are required.
The SCVA linear actuators with worm screw can be coupled in series to obtain a perfect synchronisation of operation.
All models are irreversible and with automatic stop: vibration only, and if of a considerable magnitude, can cause a movement of the load.
In this case, in order to obtain irreversibility, machines are equipped with a brake motor.
Linear actuators can be fitted with a handwheel directly connected to the worm screw, thus making it possible to manually perform any operation in case of emergency.
The self-disenganging handwheel is in accordance with accident prevention standards.
