This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X50SN, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU63-100 Standard Cylinder SU63X50SN
The AirTAC SU63-100 Standard Cylinder SU63X50SN is a double-acting profile-type standard cylinder with a Ø63mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X50SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X50SN
The AirTAC SU63X50SN is a discontinued double-acting profile-type cylinder with a 63 mm bore and 50 mm stroke, delivering 1559 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU63X50SN, a direct upgrade retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.
This NBR-sealed variant operates from -20 to +70 C. The built-in magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses modern CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X50SN carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X50SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU63X50SN Is Used
Clamping Fixtures
Secures heavy machined parts with 1559 N of thrust at 0.5 MPa, holding firmly during milling or drilling operations.
Pallet Stops
Acts as a robust pneumatic stop gate for medium-duty pallets, utilizing the compact profile body to save space.
Replacing the Airtac SU63-100 Standard Cylinder SU63X50SN with the SAU63X50SN
To replace the SU63X50SN, order the SAU63X50SN, confirming the 63 mm bore, 50 mm stroke, 3/8" port, and NBR seal. Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the 80 mm bore offers 2513 N push at 0.5 MPa; if lower force suffices, the 50 mm bore provides 982 N. For load holding, remember a plain cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve if needed. The SAU family also offers the SAUF variant with a built-in 4M solenoid valve, an option the SU line lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU63X50SN
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU63X50SN FAQ
Yes, the SU63X50SN is discontinued. The direct replacement is the AirTAC SAU63X50SN. It shares the identical 63 mm bore, 50 mm stroke, 3/8" port, output force, and SC-series mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 63 mm bore features a 3/8" port and a 20 mm rod. At 0.5 MPa it provides 1559 N push and 1402 N pull force. At 0.7 MPa push is 2182 N, and at 0.9 MPa it is 2805 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
