This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X225S, 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 SU63X225S
The AirTAC SU63-100 Standard Cylinder SU63X225S is a double-acting profile-type standard cylinder with a Ø63mm bore and 225mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X225S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X225S
The AirTAC SU63X225S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 225 mm nonstandard stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X225S, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting. The extruded aluminum body is shorter and more compact than an ISO 15552 cylinder of the same bore.
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 lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X225S 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 SAU63X225S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU63X225S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×225 | 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 SU63X225S Is Used
Package Diversion
Actuates routing gates on 3/8" port lines to push 79 kg vertical-equivalent loads smoothly using adjustable 21 mm cushions.
Clamp Actuation
Holds workpieces in machining fixtures, delivering 1559 N push at 0.5 MPa with a compact extruded profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X225S with the SAU63X225S
To replace this SU63X225S, order the SAU63X225S and verify your 3/8" port threads (PT, G, or NPT) and M16x1.5 rod-end connection. The 225 mm stroke is nonstandard (falling between the 200 and 250 mm standard marks), so confirm availability. If relying on the -S magnet for positioning, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need higher force, the 80 mm bore offers 2513 N push at 0.5 MPa; for lower loads, the 50 mm bore provides 982 N. A plain cylinder drifts without live air—the 21 mm cushions only decelerate near stroke ends—so add an external rod lock or pilot-operated check valve for secure load holding. For applications needing integrated flow control, consider the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X225S
- ✓ 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 SU63X225S FAQ
Yes, the AirTAC SU63X225S is discontinued. The direct replacement is the SAU63X225S. It matches the 63 mm bore, 225 mm stroke, 1559 N force, 3/8" port, and SC-series mounting accessories. You can swap it directly without altering your mechanical footprint.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. Push force is 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, and the theoretical max is 318 kgf at 1.0 MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement uses CMSG/DMSG/EMSG sensors.
