LKWH series hydraulic linear guide clamp is designed for ball and roller linear guide rails,widely used to lock worktables,fix positioning and suppress vibration in automation machine tools,precision machining equipment,CNC machinery and automated production lines.The clamping force is generated by hydraulic pressure and transmitted to the guide rail via pistons.If hydraulic pressure is applied to the product, it closes.

High-strength raw materials and anti-corrosion surface treatment ensure long service life and stable performance in harsh workshop environments.

-Lead Time:18days.
-Cost-Effective: 50%~70% cost savings.
-High Durability:Up to 2 million static clamping cycles.
-Broad Range of Products:For all common profile rail guides.
-Interchangeable:Completely replace the Zimmer or NBK brand KWH series hydraulic linear guide clamp.
-Machining Precision:Instead of ordinary milling,we adopt precision grinding to ensure much higher accuracy.
-Corrosion Resistance:We apply electroless sandblasting nickel plating for excellent anti-rust,anti-corrosion performance and premium appearance.(Note:the contact surface material SKD11,electroless nickel plating)
-Superior Material:We use 42CrMo alloy steel for the clamp's main body.Our clamps offer higher strength,better wear resistance and longer service life.
-Quality Control:Every clamp will go through full performance testing and inspection before shipment to ensure 100% qualified products.

-Model Code: LKWH + Guide Rail Size
-Example: For 25mm size ball linear guide rail,the complete order model is LKWH25
-Must provide the linear guide brand and complete model number;different brands have different rail profile sizes,so the matched clamping head will differ.
