Class 6
Class 6 is available for either hydraulic services up to 1500 PSI or for pneumatic services up to 250 PSI. Class 6 pneumatic cylinders have also been engineered to service low pressure hydraulic applications.
Improved Cushion Adjustment: Newly designed needle valve is interchangeable with current design and offers improved sealing characteristics.
Cushion Adjustment Needle: Needle valves and ball check drilling and machining are identical, making location of these functions interchangeable.
Piston Assembly: U-Cup packings, one piece piston.
Cushion Sleeves: Precision fitted with predetermined taper to provide gradual deceleration and reduce shock.
Cylinder Tubing:
- AIR: Hard coated aluminum, or honed, non-corrosive steel, providing an extremely wear-resistant surface and low friction characteristics.
- HYDRAULIC: Honed steel tubing standard (H6).
Piston Rod: High tensile 100,000PSI minimum yield stress proof steel, ground, polished, and flash chrome plated .0003/.0005 to provide a hard long-wearing surface with low friction but not corrosion resistant.
Tie Rod: Material alloy steel for maximum strength. Multiple tie rods in each corner are furnished on all 16” through 20” diameter cylinders.
Tube Seal: Two-step pilot recess grooves afford positive controlled squeeze on pressure sealed O-ring, while tubing locates concentrically against end cap.
Cushion Ball Check: Assures quick starting under full power; pressure acts on full piston area instantaneously.
Rod Packing: Choice of self-adjusting to pressure, multi-lip split seal or continuous pre-loaded lip seal.
Packing Gland: Readily removable long bearing type, held in place with socket head cap screws. Rod packing easily replaced without loosening tie rods or dismantling cylinder.
Rod Wiper: Wipes rod clean and dry. Keeps foreign matter from entering cylinder, extending packing life.
Rod End Threading: Choice of standard catalog male and female thread types plus standard wrench flats.
End Caps: (Cylinder Heads) Precision steel blocks.
Options
- Cushions
- Cylinder Port Location
- Water Cylinders can be engineered
Adjustable mounting allows switches to be located anywhere within range of the piston travel. Several switches may be mounted to control or initiate any squence function. Used in plant environments where dirt and contamination create difficulties for electromechanical controls.
Easily mounted in cylinder heads to confirm the position of the piston. The switch senses cushion sleeves position at the end of stroke. Being totally self contained, the switch will not be contaminated.
No contact design, has both analog and digital outputs available. Feedback sensor is protected from debris and mechanical damage.
