Air cylinder PVZ

 

MicroCentric cylinders PVZ are pneumatically operated. Air pressure flows through the rotary air distributor into the cylinder chambers. The rotary air journal has a precision guide for smooth running. The pneumatic actuation allows very fine adjustments of the clamping system giving an advantage over hydraulic cylinders.

Our cylinders PVZ-S have a built in check valve allowing the cylinder to maintain the clamping force, should a sudden air pressure loss occur. For adjustable clamping pressures all sizes are also available without check valves. As opposed to through bore cylinders LDN, the PVZ cylinders have the advantage of higher drawtube forces.

All Cylinders have a through bore as standard to bring coolant through the spindle.

PVZ cylinders can be adapted to any machine spindle by using an adapter plate. On request, MicroCentric offers adapter plates, draw tubes and several high precision clamping systems, which could easily get activated by PVZ cylinders.
