Magnetic Field Cylinders


1 Cylinder Body

Stainless Steel: Type 304 Stainless Steel manufactured to special mill specifications and tolerances to insure a long cylinder life.

Aluminum 76 Series: Thick wall hardcoated aluminum tubing exhibits excellent wear and seizure resistance while providing additional impact protection.

2 Stainless Steel Rod: Ground & Polished Type 303 Stainless Steel rods are standard on both the Stainless Steel Series and the Aluminum 76 Series. All rods have wrench flats and stress relief grooves (9/16" bore excluded).

3 Piston Rod Assembly: Piston rods are threaded, anaerobically sealed, and machine staked into the piston for triple protection. Patent pending.

4 End Caps, Piston: High strength aluminum alloy.

5 Magnet for Sensing Switch Actuation: Internal magnet specially designed for use with American Reed or Hall Effect switches.

6 Springs: Springs for spring action cylinders are made from music wire and designed for millions of cycles. Special spring forces are available.

7 Rod Guide 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.

8 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.

9 Pivot Pin/Pivot Bushing: Stainless Steel Series cylinders are shipped with plated steel pivot pins as standard. (13/4" & 2" bores supplied with pivot bushing only.) Sintered bronze pivot bushings are available as an alternative standard option. Aluminum 76 Series models all utilize the oil impregnated sintered bronze bushing as standard.

10 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.

11 Prelubricated: All cylinders are factory lubricated with a special high endurance oil mixture.

12 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.
