Work Supports / Air Advance
For Supporting Fragile Parts Or Use In Harsh Environments Available in four capacities from 1,000 to 12,500 lbs. For harsh environments (where contaminants such as aluminum or cast iron fines and corrosive or tacky coolants are present), we suggest running a constant “air-spring” to keep the plunger extended and the problem contaminants out. (You should observe air bubbles escaping around the plunger when used in this manner.) Normally retracted plungers provide additional clearance for part loading. Advance them with air pressure, exerting ONLY the force needed to “kiss” the part, then “freeze” the plunger in place hydraulically. Heavier end effectors may be used with air advance supports because of their additional air powered lifting/contact force. Special large diameter plungers and sleeves provide greater rigidity. Stainless steel plunger and sleeve assemblies help guard against corrosion in most machining environments. Standard SAE porting and alternate O-Ring manifold face seal are located in the base of the support for bolt down installation. The base can be removed for direct cartridge mounting.

* Support capacities are listed at 5,000 psi maximum operating pressure. Support capacities for other pressures must be determined by consulting the capacity graph on the next page. ** The maximum air pressure for advancing the plunger is 25 psi. Order air regulator separately. Model No. 50-0440-01 (0 to 25 psi) to more precisely control plunger advance force. *** For cartridge mount models, see cavity dimensions in this section.
