PNEUMATIC & COMPRESSED AIR Cylinder Mounting & Accessories

Hydraulic cylinders are available in a variety of styles and can be mounted in numerous ways. While they come in countless variations, they are usually built to certain standards. National Fluid Power Association (NFPA) and International Standards Organization (ISO) standards for hydraulic tie-rod cylinders are among the most common.

The advantage of standard tie-rod air cylinder mounting is their modular nature. Parts such as the head (rod-end block), cap (end opposite the head), barrel, tie rods and cylinder rod can be quickly assembled from off-the-shelf parts.
NFPA and metric ISO standards that apply to mounting types and dimensions are quite similar—they even use the same three-character code to designate mounting options.

A basic cylinder has no mounts, so users typically specify the necessary mounting type and hardware when purchasing a cylinder.

Three general styles include cylinders that have:


  • Fixed mounts that absorb force along the centerline of a cylinder.
  • Fixed mounts that do not absorb force along the centerline.
  • Pivot mounts that drive a load in a curved path.
