This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X50, 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 SU63X50
The AirTAC Airtac SU63-100 Standard Cylinder SU63X50 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 SAU63X50, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X50
The AirTAC SU63X50 is a discontinued double-acting profile cylinder with a 63mm bore and 50mm stroke, delivering 1559N push force at 0.5MPa. Its extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore, and it features a 3/8" port with M16x1.5 rod threading.
AirTAC replaced this unit with the SAU63X50, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting. The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X50 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 SAU63X50 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 SU63X50 Is Used
Mid-Tonnage Clamping
Secures heavy workpieces during machining operations, utilizing the 1559N push force at 0.5MPa to hold components rigidly against cutting loads.
Diverting Arm Actuator
Powers a robust routing arm on a packaging line, using the compact 50mm stroke to quickly push products into secondary lanes without requiring excessive space.
Pallet Stop Gate
Acts as a heavy-duty stopper for inbound pallets, absorbing kinetic energy via the 21mm adjustable air cushions at both ends to halt loads smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X50 with the SAU63X50
To replace the SU63X50, order the SAU63X50, confirming the 63mm bore, 50mm stroke, 3/8" port, and PT thread type. Because this specific SKU lacks a magnet (-S), it cannot accept a magnetic sensor; if sensing is needed, specify an SAU63X50S and use the current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. A plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. If downsizing, a 50mm bore yields 982N push at 0.5MPa; if upsizing, an 80mm bore provides 2513N. The SAUF variant integrates a 4M solenoid valve if self-switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU63X50
- ✓ 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 SU63X50 FAQ
Yes, the SU63X50 is discontinued. The direct replacement is the AirTAC SAU63X50. It shares the identical 63mm bore, 50mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 1559N push and 1402N pull force, increasing to 2182N push at 0.7MPa, with a theoretical max of 318kgf at 1.0MPa. Because this base SKU lacks a magnet, it cannot accept a sensor; the SAU replacement with a magnet (-S) uses CMSG/DMSG/EMSG switches.
