When a calibration mandrel is used, its material composition is essential. It should be made from a polymer with low friction characteristics, such as polyoxymethylene (often known as POM) or polyamide. These materials are selected because they provide a smooth...
If calibration is performed during piston insertion, the calibration sleeve must be appropriately sized to fit within the cylinder shell. This approach carries the advantage of helping align and secure other piston components, such as wear rings, during the final...
