Which OEM Cylinders Does the MI-20S Replace?
The Cylome MI-20S is manufactured to ISO 6432 — 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 DSNU / DSN
ISO 6432 · festo.com
Festo's ISO 6432 round-body mini cylinder. DSNU is the current generation; DSN is legacy. Stainless steel barrel and piston rod. Bore 8–63mm. NBR/TPE-U seals.
SMC CJ2 / CDJ2
ISO 6432 · smcusa.com
SMC's round-body mini cylinder. Lightweight, compact design for pick-and-place, sorting, and light automation applications.
Airtac MA / MAL
ISO 6432 · airtac.com
Airtac's ISO 6432 mini cylinder, widely used in Asian markets. MA is the standard round-body type; MAL is the double-rod variant.
Why ISO 6432 Guarantees Interchangeability
ISO 6432 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.
