Designed to last


Space-saving due to direct mounting on the driven machine shaft.

Cost-saving as the use of couplings (and alignment) are eliminated and no foundations are required.

Practical due to the easy adjustment of the V-belt tension by means of the torque arm.


Helical gears: as carburised, hardened and ground. 


- for gear unit types FC 116 to FC 324 : one-piece housing in special aluminium-alloy, 

- for gear unit types FC 414 to FC 822 : grey pearlitic cast iron. 

The housings are designed for optimal strength, stiffness and oil tightness.

Shafts and Bearings are adequately proportioned to allow overhung loads generated by the V-belt drive. 

Lubrication of gears by splash from the oil bath. The bearings are greased for life. 

Sealing ensured by double lip oil seals, running on plunge-ground surface.

Comprehensive range of torques and output speeds

8 gear-unit szes from 450 Nm to 7650 Nm. 

Output speeds from 12,5 to 125 min-1 with 4-pole motor (50 Hz). 

Wide range of V-belt drives.

Broad variety of options

  • Backstop
  • Adjustable motor base.
  • Extra torque-arm.
  • Intermediate sleeves (for some sizes).
