We are Manufacturer of Hydraulic Nut 3RK Type (Customise) For Slitting Machine 3RK Type Customize Hydraulic Nut For Slitting Machine Operation Principle Pressing SCREW with T-shaped WRENCH activates the pressure piston to pressurize the sealed Special Jelly, compressing "RING PISTON" and pressing "KNIFE and SPACER". the thrust power can be observed by the thrust-power indicator. Application:- 1 Setting the cutters of the slitter machine. 2 Setting forming tools. 3 Setting other arbour tooling. Up to 500% more clamping force compared to mechanical nuts Precision-engineered, hardened alloy steel components and high-pressure seals ensure “leak-proof” performance  Special seals can be installed for high-temperature use  Extra corrosion resistance through the use of electroless nickel, chrome plating or stainless steel  Reduced physical strain for setup personnel  Lighter bodies provide improved safety in handling  Aluminum nut bodies offer 60% weight reduction vs. steel
