Air cylinder LDN

The cylinders feature a precision rotary distributor which incorporates a hardened steel journal and an air bearing with an oilite sleeve.

LDN-cylinders actuated by air pressure and featuring a precision air journal assembly, pneumatics offer a much finer adjustment of draw tube force than hydraulic actuators. And MicroCentric LDN-cylinders are virtually maintenance free. The only requirements are that filtered and dry air (not oiled) is continuously supplied to the rotary air bearing during rotation.

LDN-cylinders can be adapted to any machine spindle by using an adapter plate, for actuating jaw-, collet- and diaphragm chucks. On Request, MicroCentric offers adapter plates, draw tubes and several kinds of high precision clamping systems, which could get actuated easily by LDN-cylinders.
