Pneumatic Chucks, Size : 160mm Ø To 1000 Mm Ø

Power Operated Pneumatic Front end Chucks are designed to utilise in full, the spindle bore for barpipe work. This design avoids rear mounting of the actuating cylinder and necessary draw bar connections. The chuck can be mounted on the lathe spindle with an adaptor flange as needed. The stationary air distribution system with the ports to supply air to the respective sides of the piston is mounted separately on the chuck.These power chucks are available in various sizes ranging from size 160mm Ø to 1000 mm Ø. The chucks are offered with standard jaw stroke of 4.2mm to 12mm and extended jaw stroke of 19mm to 25.4mm. The extended jaw stroke to hold pipes, casings and tool joints.For holding long oil pipes, one chuck is mounted on the front end of the spindle, and one chuck at the near end of the spindle. Power Operated Pneumatic Front end Chucks have twin non-return valves, which prevent the clamping air from returning through the port unless air is let in on the other side of the piston. This ensures retention of clamping force even when the air supply is switched off. The maximum operating pressure of the chuck is at 10 bar pressure.
