Our range of dry friction transmissions operates without lubrication and is typically coupled with worm (RS and RT series) and in-line helical gearboxes (RD series).

main ingredient
• NB input and output oil seals
• Die-cast aluminum (size 71) and gray cast iron (sizes 80 and 90) housings and covers
• Bearings with balls
• Die cast aluminium input flange

• High flexibility
• Low maintenance and management costs
• Easy to install and maintain
• reduce weight
• Quiet operation
• Wide range of uses


  • High torque even at low revolutions: thanks to the high pressures that can be reached
  • Wide range of speed variation: from zero to that of the electric motor
  • Possibility of operating in aggressive environments: water, dust, temperature, acid
  • Long service life: there are no friction elements and the components are less subject to wear since they are always lubricated
  • Reliability: the speed adjustment is always precise even after many years because it is done by modifying the stroke of the pistons
  • Cost-effectiveness: long life cycle for the connected components (there is no stress on the electric motor because it is always running at the same speed)
  • Simplicity: Adjustment is simple and intuitive, no programming is needed, and it is easy to install and start
