'^MicroCentric 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...

End caps for spindle liners are made from steel and are designed to replace the standard end cap supplied with LDZ Air Cylinders. Spindle liner end caps include (3) tapped holes that are used to mount the spindle liner to the air cylinder assembly. Model A B C End caps for rotary unions are made from steel and are intended to replace the standard end cap supplied with LDZ Air Cylinders. The threaded hole in the center of the rotary union end cap is tapped through making it possible to mount a pipe in the ID of the draw tube to deliver coolant or air to the workholding fixture.

10 kg/cm2 The HV-10 is a 3 position manually operated valve that directs and exhausts air to open and close LDZ Air Cylinders. The FRL-15 is used to set operating air pressure of LDZ Air Cylinders. This unit also provides lubrication to the rotary air bearing assembly and filters contaminants from the air supply. Water that accumulates in the filter unit can be purged by the manual drain. A pressure gage is included with each unit. 10 kg/cm2 Rotary unions can be mounted to the rear of LDZ Air Cylinders to supply coolant or air through the machine spindle to the workholding fixture.

Spindle mounting plates and draw tubes to adapt LDZ Air Cylinders to a specific machine spindle or rotary table are quoted on request. Refer to page 10 for spindle data sheet. A proximity switch kit is available for most LDZ 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 LDZ Cylinders. Special LDZ Cylinders are available with integral check valves. Check valves will maintain air pressure in the cylinder and keep the chuck...

A completed copy of this data sheet is required when LDZ Air Cylinders are supplied with spindle adapter plates and draw tubes. If the spindle of your machine has a threaded mounting or is configured differently than this diagram, a detailed drawing of the spindle must be submitted to assure that the adapter plate and draw tube that is supplied is correct. Contact us at 1-800-573-1139 if you have any questions about completing this data sheet.
