Why ISO 15552 Guarantees Interchangeability

ISO 15552 is an international standard maintained by the International Organization for Standardization (ISO). It defines the bore diameters, rod diameters, tie-rod spacing, port thread sizes, port positions, and mounting accessory interfaces for pneumatic cylinders. Any manufacturer that builds to this standard must match these critical dimensions within specified tolerances. This is why you can remove a Festo, SMC, CKD, or Parker cylinder from your machine and bolt in a Cylome cylinder without any modification — the standard guarantees it.

All Cylome cylinders undergo CMM (Coordinate Measuring Machine) dimensional verification before shipment. We guarantee 100% physical interchangeability or full refund.
