Symmetrical Berges Pulleys with Variable Speed Adjustment
Symmetrical variator pulleys are used to smoothly change the revolutions using a V-belt or variator - wide V-belt. It is made of aluminum alloy.
These are special pulleys with which it is possible to change the width setting and thus also the position of the belt. The result is a transmission with a smooth change of revolutions and gear ratio without the need to stop the transmission. Control of the width of the drive pulley, and thus the changes in speed, can be mechanical, hydraulic or electronic.
Basic types are intended for standard sizes of variator belts.

Pulleys Fields of Use
Symetrical variable speed pulleys are designed for drives with infinitely variable speed adjustment that are driven by a variable speed belt or a V-belt.
The variable speed pulleys cover a power range of 0.25 to 160 kW.
They are typically used in machines where the speed change is made mechanically, especially in presses, single-purpose machines, agricultural machines and other applications.
Pulleys Material
Aluminium alloy.
