Piston Rod

Medium carbon steel, induction case-hardened to 54 Rc, hard chrome-plated and polished to 10 RMS finish. Piston rods are made from 90,000 to 100,000 psi minimum yield material in 1/2" through 4" diameters. Larger diameters vary between 57,000 and 90,000 psi minimum yield material, depending on rod diameter. The piston thread equals the catalog style #2 rod end thread for each rod diameter to assure proper piston-to-rod thread strength. Two wrench flats are provided for rod end attachment.

Piston Rod Seal

The piston rod seal offers maximum sealing performance and efficiency with minimum friction. The highly resilient lips are pressure actuated and wear compensating, giving complete reliability through millions of cycles.

Steel Head

Bored and grooved to provide concentricity for mating parts.

Ports

NPTF ports are standards.

End Seals

Pressure-actuated cylinder tube-to-head and cap "O" rings.

Bolted Bushing

Assures true concentricity and allows removal without tie rod disassembly.

Piston Rod Stud

Furnished on 2" diameter rods and smaller when standard style #2 rod end threads are required or on 13/8" diameter rods and smaller when style #5 threads are required. Also available in 2 times the catalog "A" dimension length. Studs have rolled threads and are made from high strength steel. Anaerobic adhesive is used to permanently lock the stud to the piston rod.

Secondary Seal

Double-Service Wiperseal® - acts as a secondary pressure seal on the extend stroke and cleans the rod on the return stroke.

Long Bearing Surface

Is inboard of the seals, assuring positive lubrication from within the cylinder. An "O" ring is used as a seal between bushing and head, and also serves as a prevailing torque-type lock. Bushing material is nodular iron with flash tin plating through 21/2" dia. rods. 3" and larger bushings are bronze.

High Strength Tie Rods

Made from 100,000 psi minimum yield steel with rolled threads for added strength.

Adjustable Floating Cushions

Cushions are optional and can be supplied at head end, cap end, or both ends without change in envelope or mounting dimensions.

Cylinder Tube

Hard chrome-plated bore, steel tubing honed to a 15 micro inch finish on 11/2" through 14" bore sizes. 1" bore size is aluminum with hardcoated bore.

Align-A-Groove

A 3/16" wide surface machined at each end of the cylinder body. Makes precise mounting quick and easy.

One-Piece Nodular Iron Piston

The wide piston surface contacting cylinder bore reduces bearing loads. Anaerobic adhesive is used to permanently lock and seal the piston to the rod.

Piston Lipseal

Fully dynamic and self-compensating for variations in pressure, mechanical deflections and wear. Back-up washers prevent extrusion.
