This is a pneumatic normally open type linear guide clamping element.The LMK-B series guide clamp brake is used with ball linear guides with sizes of 15mm~65mm and can be used with most linear guide brands on the market,such as HIWIN,THK,PMI,NSK,and WON linear guides.

The rail clamp delivers strong holding force to securely fix your work slide table during critical operations.Achieve precise positioning every time,eliminate unwanted vibration,and significantly increase rigidity on linear guides – ensuring stable,accurate machining or assembly.

Pneumatic Normally Open Guide Clamping Features

Pneumatic normally open clamps that are in a loosened state when air or oil is not supplied.

Through the wedge block expanding force principle, using air pressure to realize clamping.

Compact structure with strong holding force. Novel design to avoid rigid impact when clamping.

Easy to install, directly connected with the worktable, no need to change the size of the worktable.

Precision positioning for pneumatic clamping of mo tion axes.
