Integrated Check Cushion Seal
The optional cushion seals provided with the PC and PS Series cylinders are one piece units which allow both radial and axial floating, to eliminate alignment problems. Their double action feature also eliminates the need for a check valve which requires constant maintenance.
At the end of a stroke, this cushion seal permits air to exit through the needle valve orifice only. On the return stroke, the cushion seal allows air to pass behind the piston thus obtaining a much more rapid return.
The RDC Control needle valve is designed with extra fine threads (UNEF) to obtain an easy and precise adjustment. These needle valves are normally situated on side no. 2 of the cylinder. In the case of trunnion mounting (T1, T2 and T3), the needle valve is positioned on side no. 3 of the cylinder.
Standard Piston Wear Strip
All standard pistons on PC and PS Series pneumatic cylinders are equipped with a bronze and glass impregnated teflon wear band. In addition to giving the piston a more secure fit, the self lubricating feature protects the interior surface and adds to the life of the cylinder.
Cartridge Type Gland Bushing
The gland bushing of the PC and PS Series cylinders is designed for easy removal, thus allowing easy seal maintenance without dismantling the entire cylinder. For piston rod diameters less than or equal to 1 3/4, a simple wrench may be used.
For piston rod diameters greater than 1 3/4, the nonthreaded glandbushing is held in place with a removable bolted-on plate.
