Three Position cylinders can be used when multiple positions are needed for an application. They can also be used as a multiple power cylinder if specified with a matching initial stroke and total stroke.
Type 304 Stainless Steel manufactured to special mill specifications and tolerances to insure a long cylinder life.
Ground & Polished Type 303 Stainless Steel rods are standard on the Three Position Series. All rods 1/4" diameter and larger have wrench flats and stress relief grooves.
Piston rods are threaded, anaerobically sealed, and machine staked into the piston for triple protection.
High strength aluminum alloy.
Optional internal magnet specially designed for use with American Reed or Hall Effect switches. Used for position signaling.
Standard on all models. The oil impregnated sintered bronze bushing increases the life of the cylinder rod and provides a non-abrasive bearing surface.
U-Cup seals provide low breakaway friction and maximize cylinder life expectancy. Standard Buna-N seals are recommended for operating temperatures of -20°F (-25°C) to 200°F (95°C). Fluoroelastomer seals are available for higher temperature applications. Additional special seal compounds and lubricants are available upon request.
Stainless Steel Series cylinders are shipped with plated steel pivot pins as standard. Sintered bronze pivot bushings are available as an alternative standard option. (2" bore is supplied with pivot bushing only.)
Precision machined rod seal groove provides a smooth sealing surface while positively retaining the seal without requiring additional components and relying on press fit containment.
All cylinders are factory lubricated with a special high endurance oil mixture.
The quality of each cylinder is assured by testing each unit for leaks and tested prior to shipment. Quality control provides added value to American cylinders.
