Three Position Cylinders
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.
STANDARD FEATURES AND BENEFITS
Stainless Steel Cylinder Body
Type 304 Stainless Steel manufactured to special mill specifications and tolerances to insure a long cylinder life.
Stainless Steel Rod
Ground & Polished Type 303 Stainless Steel rods are standard on the Aluminum 76 Series. All rods have wrench flats and stress relief grooves.
Piston Rod Assembly
Piston rods are threaded, anaerobically sealed, and machine staked into the piston for triple protection.
End Caps, Piston, Center Section
High strength aluminum alloy.
Magnet for Sensing Switch Actuation
Optional internal magnet specially designed for use with American Reed or Hall Effect switches. Used for position signaling.
Rod Guide/Center Bushing
Standard on all models. The oil impregnated sintered bronze bushing increases the life of the cylinder rod and provides a non-abrasive bearing surface.
Buna-N U-Cup Rod & Piston Seals
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.
Pivot Pin/Pivot Bushing
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.)
Rod Seal
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.
Prelubricated
All cylinders are factory lubricated with a special high endurance oil mixture.
Pre-Tested
The quality of each cylinder is assured by testing each unit for leakage prior to shipment. Quality control provides added value to American cylinders.
