Piston Road 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.

Bolted Bushing

Assures true concentricity and allows removal without tie rod disassembly.

Primary Seal

"Tuffseal" Special polyurethane seal is a proven leakproof design, which incorporates the pressure-compensated unidirectional characteristics of a "U CUP" with the multiple edge sealing effectiveness of compression-type stacked-packings.

Secondary Seal

Double-Service Wiperseal® (Patent #2907596) - acts as a secondary pressure seal on the extend stroke and cleans the rod on the return stroke.

Piston Rod

Medium carbon steel, induction case-hardened to 54Rc, 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.

Long Bearing Surface

Is inboard of the seals, assuring positive lubrication from within the cylinder. An "O" ring is used as a seal between gland 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.

Piston Lipseal

Zero leakage under static conditions. Seals are selfcompensating to conform to variations in pressure, mechanical deflection, and wear. Backup washers prevent extrusion.

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.
