MicroCentric is not only committed to building the world's finest workholding products, but we also strive to provide our customers with the best solutions for their machine tool applications, and provide unmatched service and support. LDZ Air Cylinder Design & Features MicroCentric LDZ Air Cylinders feature a high performance precision rotary air bearing assembly. The air bearing incorporates a hardened steel journal and a housing supported by high speed ball bearings. This advanced proven design is combined with MicroCentric's precision manufacturing capability to produce a line of air cylinders of unmatched performance and reliability. Air cylinders offer fine adjustment of draw tube force to prevent distortion of workpieces during clamping as compared to hydraulic actuators. And MicroCentric LDZ Cylinders are virtually maintenance free. The only requirements are that air is continuously supplied to the rotary air bearing during rotation, and that the air is filtered and lubricated. LDZ Air Cylinders can be adapted to all machine spindle and rotary table configurations to actuate jaw, collet, and diaphragm chucks. MicroCentric will supply spindle mounting plates and draw tubes as required, as well as a variety of precision workholding products to interface with LDZ Cylinders.
