Series VH Series VH very heavy-duty hydraulic cylinders are premium quality cylinders with operating capacities of,000 PSI. They fully meet NPA standards. And to make sure every cylinder is premium-quality, Parker Hannifin subjects each and every one not just batch samples to tough inspection and performance tests. OTHR SRIS VH ATURS AND SPCIICATIONS Ports Series VH ports are two sizes or larger than NPA standards. Standard location is position as shown in dimensional drawings. here mountings do not interfere, ports may be located at positions,, or. Ports are not available at positions or on mounting style C, /" thru " bore cylinders. SA straight thread O-ring ports will be supplied unless otherwise specified. Cushions Cushions on Series VH cylinders are " long on all sizes except /" and " bore sized equipped with " and /" diameter piston rods which are supplied with cushions /" long at head end. Self-centering floating cushion sleeve at head end and cushion spear at cap is tapered for / its length to give maximum cushioning effect for / its length. Thrust ey An extended retainer plate, to serve as a thrust key, can be supplied on mounting styles C and. The thrust key would be the same as used on Parker Hannifin H hydraulic cylinders.
