Which OEM Cylinders Does the ADN-20S Replace?
The Cylome ADN-20S is manufactured to ISO 21287 — an internationally recognized dimensional standard that guarantees physical interchangeability between any compliant cylinder, regardless of manufacturer. This means our 20mm bore cylinder is a 100% drop-in replacement for the following major OEM brands — same mounting holes, same port positions, same tie-rod spacing. No machine modification required.
Festo ADN / ADVC
ISO 21287 · festo.com
Festo's compact cylinder series with 350+ variants. Self-adjusting PPS cushioning. Up to 50% less installation space than ISO 15552. Bore 12–125mm.
SMC CQ2 / CDQ2
ISO 21287 · smcusa.com
SMC's compact cylinder series. Lightweight with auto-switch mountable on 2 or 3 sides. Wide bore and stroke options for space-critical applications.
Parker P1P-S
ISO 21287 · parker.com
Parker's ISO 21287 compact cylinder. Short overall length, sensor-ready, multiple mounting options including through-hole and internal thread.
Why ISO 21287 Guarantees Interchangeability
ISO 21287 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.
