Description:

Designed for mining equipment drives. the advantage of this model is the presence of four pistons, the number of power parts is significantly reduced (consists of two cast-iron semi-blocks, a steel rotor, four pistons). The replacement of aluminum pistons with steel ones and the use of special locking, modified piston pins greatly increase the reliability of the piston group robots and increase the life of the engine.

Overview:

Pneumatic motors can be mounted on the machine at the end of the half block with two bolts on either side, through elongated bolts or using a flange.
