Adjustable Cushions

Unique, optional adjustable cushions reduce shock and cushioning time, permitting quick out-of-cushion starts, increasing machine cycle rates. Series A-Adjustable Series J-Self Adjusting

Piston Seals

Durable U-cup seals are mechanically locked in place to prevent rolling and blowout. Temperatures to 180°F standard. To 450°F when using optional spring loaded Teflon® U-cup seals. Series A-Buna-N Cup Seals Series J-Teflon® Cup Seals

Piston

One-piece piloted piston provides maximum strength and protection against shock loads. Piston threads increase in size for added strength when oversized rods are required.

Tube End Seal

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

Bushing

Nodular iron piloted bushing provides 400% longer bearing life than conventional bronze bushings. Protects against side loads. Removes easily using a common Allen wrench. Cylinder tie-rods not disturbed.

Rod Seal

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

Wear Band

Durable, non-metallic piston wear band prevents metal to metal contact, which can score expensive tubing. Pistons never have to be replaced.

Tube

Series A-Chrome plated I.D. 0.0003 - 0.0005 thick. Resists wear and corrosion. Series J-Steel Tube

Tie Rods

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

Series A - Pre-Lubricated

A generous quantity of a water resistant lubricant is added during assembly, assuring permanent lubrication.

Piston Rod

Case-hardened to 50-55 Rockwell C and chrome-plated rod resists mechanical damage and wear from side loads.

Wiper Seal

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