Pneumatic cylinder with 2 pistons is a perfect solution if you wish to increase theclamping force without interfering with machine design. Two parallel pistons allowsyou to achieve a double pulling and pushing force compared to 1-piston cylinderswith the same diameter. It is a result of the air pressure on a double piston area
Clamping force is set by smooth adjustment of air pressure in the valves
The rotary pneumatic cylinders without through-hole are technologically advancedproducts featuring high rotating speeds, operational safety system and reliability
They are mainly used to drive the lathe chucks and special powered fi xtures operatingin a horizontal positioning system
Compressed air powered
Max. operating pressure 0,63MPa
Unbalance G 6.3

Short form (2/3 of standard model length)
Large through-hole
The piston stroke control system located in the rear side of the cylinder isactuated via two proximity switches. These switches are not included in the delivery
They are mainly used to drive the lathe chucks and special powered fi xtures operatingin a horizontal positioning system
Built-in non-return valve maintains a constant pressusre fl ow in the powered pistonchambers in case of oil supply disruption or power pressure drop
Rear and front mount with screws
Unbalance G 6.3

Rotating hydraulic cylinders, of type 1305, with a through-hole are technologically advanced products featuring high rotating speeds and operational safety systems
The piston stroke control system is located in the rear side of the cylinder and may include two proximity switches (SDC cylinders) or a linear positioning system with one proximity switch (SKC cylinders).
