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.
As a professional manufacturer of pneumatic normally closed clamps,we deliver superior clamping solutions for industrial applications worldwide.Our pneumatic NC clamping elements ensure reliable safety and precision in machinery,automation,and assembly processes,meeting rigorous operational demands.We help you reduce total clamping costs by 20% to 50% compared to standard market prices.With extensive in-house inventory,our pneumatic normally closed brakes ship promptly—eliminating long lead times and keeping your projects on schedule.
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: 25%~50% cost savings.
High Durability:Up to 5 million static clamping cycles.
Broad Range of Products:For all common profile rail guides.
