AiROYAL Cylinders

Hydraulic and Pneumatic Cylinders

Small Bore Cylinders

• For Air, Oil, Water, Vacuum
• Air Pressure to 150 PSI
• Oil Pressure to 2000 PSI
• Bores – 5/8″, 1″, 1 1/2″, and 2″

Small-bore, heavy-duty industrial cylinders. They fill the need for small diameter cylinders of rugged construction and exceptionally high quality.

Pressure rating according to service. Four bores, 5/8″ to 2″ and choice of standard or oversize rods.

Air cylinders are solid brass construction. Hydraulic cylinders have steel barrels with brass ends except 5/8″ bore which is all brass. Cylinder rods are 416 stainless steel. Piston and rod seals are self-adjusting. Seals are of synthetic rubber, usually cup-type on air cylinders, multiple-V on hydraulics, O-rings on vacuum cylinders and on 5/8” bore cylinders.

Bore and Rod Diameters

Oversize rods are available for all except 5/8″ bore double-end-rod cylinders.

External stops are required on the extension stroke of 1″ bore cylinders with 3/4″ rods.

All rod threads are NF and are full diameter of the rod.

Stroke Lengths Available

Double-acting cylinders are available in even increments up to 120 inches. Other fractional lengths carry a price additive. On long strokes, you may need an oversize piston rod to prevent buckling. Single-acting cylinders are available in 1/2″ increments up to 4″. Longer strokes are on a custom quote basis from the factory.

Cushions and Flow Controls

Cushions are available for all sizes of hydraulic cylinders. Not recommended for air cylinders and not available for vacuum cylinders. If cushions are desired, specify rod end, blind end, or both ends.
Flow controls are similar to cushions but are effective throughout the entire stroke. They are built into the cylinder if specified on order. The standard practice is to supply them with free-flow return check valves. To order, specify meter-out flow control in rod end, blind end, or both ends.

Miscellaneous Options and Special Features

Certain special options are available if specified on your order. Please refer to Airoyal catalog for details. Options include rod wipers, rod scrapers, hard chrome plating on rod, special seals, special threads, oversize ports, double ports, and others. Wrench flats are standard on all models.

Rotary Torque Actuator

AiROYAL CYCLROTOR® is a cylinder-actuated rotary torque actuator which is ideally suited for rotary machine motions, disappearing stops, limited rotation valves, conveyor gates, and many other applications.

Cylinder actuated, rack and pinion rotary actuator. Will operate at 150 PSI air or 500 PSI hydraulic.

Angle of shaft rotation must be specified on order. Choice of 1/4-turn (90º), 1/2- turn, 3/4-turn, or full 360º.

Options available which must be specified on order: special angle of rotation (if required); speed control valves for either or both directions; cushions on either or both ends of rotation; adjustable stroke stop at either or both ends of rotation; or double shaft. Also state whether for air or oil use.
