Single and Double Acting Telescopic Hydraulic Cylinders
Parker is one of the largest independent manufacturers of single-acting telescoping hydraulic cylinders. Built to customer prints or per application specifications as either single- or double-acting to fit the needs of a range of applications.
Features include:
• Longer sleeve overlap for improved stability and higher column loading.
• Nylon tipped set screws that conform to the shape of the packing nut threads. It is nearly impossible for the packing nut to back off accidentally.
• Snap-on, glass-filled bearings that absorb contaminants without damaging cylinder walls.
• Threaded steel stop rings for easier servicing and more reliable stopping action.
• External packing nuts give added support to the tube exterior while making service procedures easier.
• Wave springs and chevron packing for self-compensating seals.
• Polyurethane rod wipers that resist higher temperatures without extrusion.
• Positive manual air bleeder prevents cavitation and “mushy” cylinder action.
• Cast steel mountings offer dependable strength. Pin-eye and rod-end are welded into a single unit.
• Various materials and coatings including Stainless Steel, Electroless Nickel, Chrome, Double Chrome and Nitriding
Available with:
• Bore sizes – up to 20”
• Stroke – up to 500"
• Various Operating Fluids
• Batch Sizes 1PC to 100’s
• Operating pressures – up to 10,000 PSI
Typical Options:
• Load holding valves
• Flow controls and fuses
• End of stroke cushions
• Electro-Hydraulic Transducers
• End of Stroke Hydraulic Cushions
• Protective Rod Boots
• Proximity Switches
Every cylinder is individually tested before leaving our plant to assure proper performance and leak-free operation. All Parker cylinder products carry an eighteen month warranty.
