LMK-R series pneumatic normally open clamping elements are specially engineered for roller linear guides,perfectly compatible with most mainstream roller linear rail sizes from 25mm to 65mm.We maintain abundant in-stock supply to support fast delivery globally,helping you cut overall procurement costs by 50%~70% without compromising performance and reliability.


-The structure is compact and the holding force is strong.
-Precise positioning, suitable for pneumatic clamping of moving axes.
-Through principle of wedge block expansion,air pressure is used to achieve clamping.
-Easy to install,directly connected to the workbench,no need to change workbench size.

Pneumatic Normally Open Rail Clamp Advantages:
-Lead Time:Large stock inventory.
-Cost-Effective: 50%~70% cost savings.
-High Durability:Up to 5 million static clamping cycles.
-Broad Range of Products:For all common profile rail guides.
-Completely replace the Zimmer or NBK brand MK series linear guide clamp.
-Customizable Design:Tailored to meet specific application requirements.
-Machining Precision:Instead of ordinary milling,we adopt precision grinding to ensure much higher accuracy.
-Quality Control:Every clamp will go through full performance testing and inspection before shipment to ensure 100% qualified products.
-Superior Material:We use 42CrMo alloy steel for the clamp's main body,while most other Chinese suppliers use C45 steel.Our clamps offer higher strength,better wear resistance and longer service life.
-Corrosion Resistance:We use electroless sandblasting nickel plating,which provides excellent anti-rust and anti-corrosion performance,a premium appearance,and resistance to scratching or peeling after long-term use.
