LDN Air Cylinder Design & Features
MicroCentric LDN Air Cylinders feature a high performance sealed design air bearing assembly. The air bearing incorporates a hardened steel journal and a housing supported by high speed sealed bearings. This advanced design combined with MicroCentric's precision manufacturing capability produces air cylinders of unmatched performance and reliability.

Air cylinders enable fine adjustment of draw tube force (clamping force) to prevent distortion of workpieces during clamping compared to hydraulic actuators. MicroCentric LDN Cylinders are maintenance free, requiring only filtered air to be provided continuously to the air bearing assembly during rotation.

LDN Air Cylinders can be adapted to all machine spindle and rotary table configurations to actuate jaw, collet, and diaphragm chucks. MicroCentric can supply spindle mounting plates and draw tubes as required, as well as a variety of precision workholding products.

Mounting Plates & Draw Tubes

 N/A Spindle mounting plates and draw tubes to adapt LDN Air Cylinders to a specific machine spindle or rotary table are quoted on request. a1146.jpg

Proximity Switches

 N/A A proximity switch kit is available for most LDN Cylinders. Proximity switches provide a signal to the machine control to confirm whether the chuck or workholding fixture is clamped or unclamped.

Contact our sales engineers for information on proximity switch kits for LDN Cylinders. a1147.jpg

Check Valves

 N/A Special LDN Cylinders are avail able with integral check valves. Check valves will maintain air pressure in the cylinder and keep the chuck or workholding fixture clamped in the event there is an interruption to the air supply.

Contact our sales engineers for information on LDN Cylinders with check valves. a1148.jpg
