LMKS-B Series Pneumatic Linear Rail Clamping Element

LMKS-B series pneumatic normally closed linear guide clamp automatically maintains the rigid clamping state of the linear rail when there is no air pressure supply.This clamping element is specially developed for ball linear guides with specifications of 15mm~65mm.It is compatible with mainstream brand linear guides such as HIWIN,THK,PMI NSK,WON,etc.,and can be quickly installed without customized modification.

Features of Pneumatic Normally Closed Rail Clamp

-The surface of the pneumatic clamping element main body is nickel-plated and has good rust resistance.

-When there is air pressure,the linear rail clamp is released;when there is no air pressure,the linear guide is clamped by spring force.

-Depending on the holding force requirements of the clamping mechanism,standard connection or pressurized connection can be used.

Pneumatic Normally Closed 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 MKS 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.
