Hydraulic Rotary Cylinders
Hydraulic rotary cylinders sit on the spindle rear and pull the drawbar that opens and closes the power chuck. Drawbar pull is published at 25 kg/cm² so the force on the jaws is a known number, not a hope. Sized to the CBC 90–200 range for the matching chuck series.
Ports
3/8 inch BSP hydraulic connections.
Mount
PCD and bolt pattern listed per model.
Rating
Drawbar pull at 25 kg/cm² and maximum RPM.
