A comprehensive range of variable speed pulleys by German manufacturer Berges Antriebstechnik GmbH are available through their Australian representatives PT Link Sales Pty Ltd.
The variable speed pulleys can be selected as individual units (spring loaded driver type) or as a combination of two units (adjustable control driver and spring loaded driven type).
The Berges variable speed pulley sets (combination of two units) are offered with a symmetrical housing with IEC dimensions suitable for interface with standard electric motors and reduction gearboxes.
Many international manufacturers of gearboxes and geared motors (including seven popular brands found in Australia) prefer to use the Berges variable speed pulley system as a standard option to their product program and there are thousands already in use throughout Australia in numerous industrial sectors.
All variable speed pulley sheaves are roller burnished as standard to attain a greater resistance to wear, which leads to longer service life. Cold forming increases strength by approximately 25%.
The V-shaped symmetrical cross sections of the Berges variable speed pulleys combine high power transmission (up to 160kw) with low mass and high belt speeds thanks to their uniform flank contact forces.
PT Link Sales Pty Ltd offer an additional service to customers by supplying a complete variable speed pulley drive package in U or Z configuration and in flange or foot mounting.
This service extends to the customer supplying their own electric motor and gearbox as free issue to be integrated within the variable speed pulley drive package.
PT Link Sales Pty Ltd offer technical support for all Berges variable speed drive pulleys from single pulley standard section V-belts to double pulley wide section belts.
