Flange mounting chuck<br />
B.AC<br />
Flange mounting type chucks B.AC are utilized on rotary table transfer machines to<br />
firmly hold components to be processed.<br />
They can be either pneumatically or hydraulically operated.<br />
Max pneumatic operating pressure is 9 bar.<br />
Max hydraulic operating pressure is 25 bar.<br />
Clamping force at 9 and at 25 bar are proportional to the ones relative to 12 bar as<br />
shown in the chart below.<br />
Soft jaws, extra long jaws strokes or twin-in line locking cylinder, can be supplied on<br />
request.<br />
