The bore diameter typically ranges from 40 to 200 mm, as listed in the directory. This range is a reference; the actual bore size must be selected based on the required force output and confirmed with the manufacturer.
Operating pressure, typically 16–35 MPa, determines the force output. Higher pressure increases the force but also increases wear on seals and components. Always verify the maximum pressure rating with the supplier.
Seals are commonly made of polyurethane or nitrile, with FKM available for high-temperature applications. Rods are typically chrome-plated steel, and the piston rod material may be 45# or 40Cr. Confirm material compatibility with your fluid and environment.
Surface roughness, typically Ra 0.2–0.4 μm, is critical for seal performance. A smoother finish reduces friction and wear, extending seal life. Verify the specified roughness with the manufacturer to ensure proper operation.
