Compact interchangeable air cylinders that are loaded with features and benefits.

Value-Added Features

Stainless steel tie bolts and aluminum spacers lock precision machined heads tightly around a unique, high strength, composite cylinder tube. The tube is extremely smooth, the self-lubricating interior surface insures highly reliable performance and extended seal life. Its high impact resistance reduces chances of cylinder failure due to dings or dents. Zero slip-stick avoids problems that metal cylinders encounter when they sit in a static condition for extended periods of time. Combined with hard chrome plated stainless steel piston rods and a unique, non-metallic rod bearing.

Exceptional Piston Rod Bearing

The better the bearing, the more cycle life you can expect from your air cylinders. The NB Series cylinders incorporate a truly superior rod bearing material - Duralon®. Duralon® is a composite with a PTFE/ Dacron® fabric liner bonded to a supporting filament-wound, high strength, fiberglass and epoxy resin shell. Resistant to corrosion, moisture and temperature to 325 °F, the bearing is reliable in any environment. It has an extremely high load bearing capacity, very low friction, and will not gall or score the piston rod.

Non-Rotating Twin Rod

Twin piston rods are incorporated into the cylinder head to achieve NON-ROTATION. The rods are securely fastened to the piston and tied together externally by a rod end tool bar. The tool bar insures that the rods move in tandem and provides an ideal mounting surface for any attachments required by your application. The tool bar is furnished with threaded mounting holes or optional counter-bored mounting holes.
