Product description

The expandable-disc pulleys (divided into two large families) are the most simple and economic solution for changing rapidly and continuously the rotation speed of two shaft, without having to stop the transmission.


Benefit of our models ...

- Good reliability.
- Wide selection.
- Easy installation.
- Highly accurate manufacturing.
- Competitive pricing without sacrificing quality.
- "Made in Italy" with certified quality.


Our main product range

- "VARIABLE CENTRE DISTANCE": consisting of two plates sliding symmetrically on a hub, transmits motion to a "fixed" driven pulley with variation ratios up to 1:3.5, by varying the distance between the centres of the two pulleys.

- "FIXED CENTRE DISTANCE": consists of a pair of pulleys, both with a single mobile disc that makes it possible to vary the speed with a ratio of up to 1:12,3 by varying of the handwheel on the driving pulley.

All products offered by this exhibitor

Modular torque limiters "DSM"

A robust torque limiter with modular torque adjustment. Free rotation after overload permits high rotational speeds with also high torque settings and large shaft diameters can be accommodated. The torque modules can be individually adjusted and re-engagement of the unit is quick and easy.read more

Bellow coupling "GSF"

The GSF bellow couplings have been designed and manufactured for all applications requiring excellent dynamic characteristics, necessary for high speeds, fast reversing and, at the same time, torsional rigidity with low inertia without compromising the high reliability. The coupling is made in three ...read more

Couplings with spacer

Shafts "backlash" to connect in a simple and fast two or more components of a mechanical transmission far between. The size of the extension is customizable to obtain a specific DBSE with different types of locks on the trees. Lengths up to 3 meters without intermediate support.read more

Torque limiter for reducers "PR"

Safety coupling to be mounted between the motor and gearbox with flange B5 spacer. Available in sliding (DF) and disengage versions (DSS/F/SG-PR-V). The location of the limiter between the motor and gearbox requires a smaller size of device with also reduces costs.read more

Balls or Rollers torque limiters "DSS or DSR"

Overload protection device with Ball or Roller transmission, which disengages fully at the pre-set peak torque. The torque is steplessly adjustable by altering the spring pressure. - Precise torque setting by adjusting the radially balanced locking nut. - The innovative regulation of the nominal ...read more

Elastomeric couplings - Rigid couplings (backlash free)

The aim of the flexible coupling is to transfer motion between two shafts on the same axis whilst accounting for possible misalignments. We have various styles of flexible couplings suitable for a wide range of applications. The quality of the materials used, the careful design and the precision in manufacturing ...read more

Friction torque limiter DF

Overload protection device with a sprocket mounted between two friction discs that slide without disengaging when it reaches the pre-set peak torque. The torque is adjustable by altering the spring pressure. - Compact solution. - Assembly with helical springs possible: /CM. - Available with anti-corrosive ...read more

Economic ball torque limiter EDF/F

Economical overload protection device with ball transmission via a customized sprocket that disengages fully when it reaches the pre-set peak torque. The torque is steplessly adjustable by altering the spring pressure. - Reduced torsional backlash by ball drive. - Maintenance free for long lasting, ...read more

Backlash free torque limiter DSS/SG

A backlash free overload protection device with ball transmission, that disengages fully at the pre-set peak torque. Very high sensitivity possible with negative spring version. - Exact torque regulation through a balanced radial nut. - Innovative calibration system by quote "H" for an immediate calibration ...read more

Pneumatic clutches "AP"

"Pneumatic" safety devices which disengaging mechanically at the fixed calibration torque, protect the components of a transmission against possible functioning defects, with the ENGAGEMENT - DISENGAGEMENT transmission feature, freely rotating on ball bearing. - Simple and precise calibration. - Transmission ...read more
