Specifications subject to change without notice or incurring obligation 3 4-1-08 Longstroke ™ Cylinders Cylinder OD – is clear anodized aluminum for corrosion resistance and an attractive appearance. The Bore ID is Hard Anodized – Hard anodizing is an electrochemical process which provides a very dense surface of aluminum oxide that actually impregnates the base aluminum. It forms an extremely hard (60 Rc) surface with a low coefficient of friction. Hardness, corrosion resistance and wear resistance exceeds that of chrome plated steel. An Extra Long Rod Bearing – provides long and rigid support for the piston rod.The bearing material is Duralon ® on all bore sizes. See page 3.2 for a chart comparing the exceptional physical properties of Duralon ® to other common, though less durable, bearing materials. The Piston Rod – is Hard Chrome Plated Stainless Steel. The standard rod end is fine female thread tapped and has long wrench flats.
