Which OEM Cylinders Does the DNC-50S Replace?
The Cylome DNC-50S is manufactured to ISO 15552 — an internationally recognized dimensional standard that guarantees physical interchangeability between any compliant cylinder, regardless of manufacturer. This means our 50mm 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 DSBC
ISO 15552 · festo.com
Festo's current-generation ISO 15552 standard cylinder with self-adjusting PPS cushioning. Available in bore 32–125mm, stroke up to 2800mm. Operating pressure 0.1–12 bar.
Festo DNC (Legacy)
ISO 15552 / ISO 6431 · festo.com
Festo's legacy ISO 15552 cylinder, widely installed globally since the 1990s. Millions still in service. Same ISO 15552 mounting dimensions as DSBC — all Cylome cylinders fit both.
SMC CP96
ISO 15552 · smcusa.com
SMC's ISO 15552 tie-rod cylinder with enclosed tie rods and profile tube design. Up to 15% weight reduction. Air cushion + bumper cushion for low noise.
CKD SCA2 / SCWP2
ISO 15552 · ckd.co.jp
CKD's medium-bore ISO 15552 cylinder. SCA2 covers 40–100mm bore; SCWP2/SCWT2 covers 32–100mm. Multiple variants including heat-resistant, low-friction, and coolant-proof.
Parker P1F-S
ISO 15552 · parker.com
Parker Hannifin's ISO 15552 profile cylinder. Sensor-ready with T-slot grooves on all sides. Magnetic piston standard.
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.
