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.
