Roller Screw versus Ball Screw Actuators
In the ever-evolving field of engineering, roller screw technology has become a significant force in linear electric actuator motion control....
High efficiency Torriani worm gear slewing drive with smaller pitch of the worm and larger contact surface on multiple teeth of the wormgear. This slewing ring drive is ideal for vertical applications and is up to four times faster than the standard version. Compact slewing drive thanks to the lower assembly position.
A worm gear slewing drive is a complete slewing solution in a closed housing with a slewing ring bearing with external gear, combined with a direct mounted with bearing supported steel worm shaft. The self-locking ability of the slewing drive eliminates the need for a brake on the drive (hydro)motor.

This turbine extinguisher is used on various types of fire engines. This allows intense fires to be extinguished from a great distance with high pressure using water or foam.
In the retracted position, the turbine is recessed into the roof of the fire engine and is not visible. In the event of a deployment, it is pushed up through the roof.
The extinguishing turbine is lifted using 4 lifting spindles of the MH-R type equipped with a ball screw with barrel nut. The spindle lifting elements are mechanically linked to each other, so that the system can be driven with 1 motor.
There are various options for the rotating movement, including the swivel unit G-CH series.
The enclosed and sealed housing of the slewing drive protects against dust and dirt.
We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.
In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
