This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X15, 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 SU63X15
The AirTAC Airtac SU63-100 Standard Cylinder SU63X15 is a double-acting profile-type standard cylinder with a Ø63mm bore and 15mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X15, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X15
The AirTAC SU63X15 is a discontinued double-acting profile-type cylinder with a 63mm bore and 15mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X15, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
Because this specific SKU lacks a magnet, it cannot accept a sensor. The SAU successor 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 SAU63X15 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 SAU63X15 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 SU63X15 Is Used
Short-Stroke Clamping
Ideal for holding heavy metal castings during machining, using the 1559N push force across a very compact 15mm travel distance.
Package Diverting
Provides robust actuation for heavy-duty package routing gates where a 63mm bore delivers fast, positive displacement at line speeds.
Replacing the Airtac SU63-100 Standard Cylinder SU63X15 with the SAU63X15
To replace this SU63X15, order the SAU63X15. Verify your 3/8" port thread (PT, G, or NPT) and M16x1.5 rod-end connection. This non-magnetic SKU cannot support sensing; if you need position detection, specify an SAU model with an -S suffix and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For higher force needs, an 80mm bore yields 2513N at 0.5MPa; for lighter loads, a 50mm bore provides 982N. Remember, a standard cylinder drifts without live air—the 21mm cushions only decelerate end-of-stroke. Use an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X15
- ✓ 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 SU63X15 FAQ
Yes, the AirTAC SU63X15 is discontinued. The direct replacement is the SAU63X15. It shares the same 63mm bore, 15mm stroke, 3/8" port, output force, and SC-series mounting, so it drops right into your existing application.
At 0.5MPa it pushes 1559N and pulls 1402N. It pushes 2182N at 0.7MPa and 2805N at 0.9MPa, with a theoretical max of 318kgf at 1.0MPa. The 21mm cushions only decelerate the piston; they do not hold loads on air loss. Use an external rod lock for holding.
