This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X10S, 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 SU63X10S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X10S is a double-acting profile-type standard cylinder with a Ø63mm bore and 10mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X10S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X10S
The AirTAC SU63X10S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 10 mm stroke, delivering 1559 N of push force at 0.5 MPa. AirTAC replaced this unit with the SAU63X10S, a direct upgrade sharing the exact same extruded body, 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware.
Because this SKU includes a magnet (-S), it originally worked with legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X10S 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 SAU63X10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×10 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X10S Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, utilizing the 10 mm stroke and 1559 N push force to secure heavy workpieces firmly without excessive travel.
Package Diverting
Provides a compact 63 mm bore profile to push items off a production line, fitting neatly into tight conveyor frames while delivering reliable lateral force.
Ejector Mechanisms
Suitable for quickly ejecting molded or stamped components from machinery, where the short stroke ensures rapid cycling and minimal footprint.
Replacing the Airtac SU63-100 Standard Cylinder SU63X10S with the SAU63X10S
To replace this discontinued SU63X10S, order the SAU63X10S. Verify your 3/8" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB). Because this is an -S magnet model, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need load holding on air loss, note that a plain cylinder drifts—the cushion only decelerates; add an external rod lock or pilot-operated check valve. For higher force, the neighbouring 80 mm bore offers 2513 N push at 0.5 MPa; for lighter loads, the 50 mm bore provides 982 N. If you want self-switching, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X10S
- ✓ 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 SU63X10S FAQ
Yes, the SU63X10S is discontinued. The direct replacement is the AirTAC SAU63X10S. It shares the identical 63 mm bore, 10 mm stroke, output force, 3/8" port, and SC-series mounting, so it fits the same application directly.
The 63 mm bore delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because this is an -S model, the original CS1-B/DS1-B sensors are obsolete; the SAU replacement requires CMSG/DMSG/EMSG switches.
