Cushion

Unique, optional, self-regulating cushion automatically adjusts to pressure, load and speed variations. This reduces shock and cushioning time, which permits quick out-of-cushion starts, thus increasing machine cycle rates.

Piston Seals

Rugged PTFE U-cup seals are mechanically locked to prevent rolling or blowout. Temperatures to 200°F standard. To 450° when spring-loaded.

Piston

One-piece piloted piston provides maximum strength. Piston threads increase in size for added strength when oversize rods are required.

Tube End Seal

PTFE "SHEF" tube-end seal resists heat, extrusion, shearing, and hydraulic fluids. Patented strip-type seal repairs all bore sizes with minimum inventory and downtime.

Rod Seal

Durable urethane rod seal is pressure-energized and wear-compensating for long, leak-free service.

Bushing

Nodular iron bushing provides longer bearing life than conventional bronze bushings. Protects against side loads. Removes easily using a common Allen wrench. Cylinder tie rods not disturbed.

Ports

SAE "O" ring ports are standard. NPTF ports are optional.

Piston Wear Band

Durable, non-metallic (11/2" - 6" Bores, bronze 7" -20" bores) piston wear band reduces possibility of damaging piston which can score expensive tubing. Reduces need for piston replacement.

Piston Rod

Case-hardened to 54 Rockwell C and chrome-plated rod resists mechanical damage and side loads.

Tie Rods

High strength, 100,000 to 125,000 PSI minimum yield material. Provides protection against shock pressures.

Wiper Seal

Wipes away dirt that may have accumulated on piston rod and prevents it from entering bushing. Also provides secondary rod seal.
