This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X131S, 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 SU63X131S
The AirTAC SU63-100 Standard Cylinder SU63X131S is a double-acting profile-type standard cylinder with a Ø63mm bore and 131mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X131S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X131S
The AirTAC SU63X131S is a discontinued double-acting profile-type cylinder with a 63mm bore and 131mm stroke. Because 131mm is a non-standard stroke, expect extended lead times or a custom spacer. The direct replacement is the SAU63X131S, matching the 3/8" port, M16x1.5 rod thread, and SC-series mounts.
Upgrading to the SAU keeps the same compact extruded aluminum body but moves the -S magnet to the modern CMSG/DMSG/EMSG sensor family (the SU used legacy CS1-B/DS1-B switches). The SAU line also adds a SAUF variant with a built-in 4M solenoid valve that the SU lacked. Note that air cushions only decelerate the piston; they do not hold load on air loss, so use an external rod lock for vertical safety.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X131S 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 SAU63X131S 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 SU63X131S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×131 | 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 SU63X131S Is Used
Carton Diverting
Uses the 1559N push force at 0.5MPa to push heavy cardboard cartons cleanly onto parallel packaging lines without stalling.
Pallet Stopper
Acts as a robust pneumatic stop for inbound pallets, relying on the 63mm bore's 1402N pull to retract clear of forklift traffic.
Clamp Actuation
Drives medium-duty workholding clamps on machining fixtures, where the compact profile body saves valuable floor space.
Replacing the Airtac SU63-100 Standard Cylinder SU63X131S with the SAU63X131S
To replace this SU63X131S, order the SAU63X131S. Verify your 3/8" port threads (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, TC). If your stroke can be standardized, moving to 125mm or 150mm avoids the non-standard 131mm delay. Sizing both ways: a 50mm bore gives 982N push @0.5MPa, while an 80mm bore gives 2513N. If you need self-switching without external plumbing, consider the SAUF valve-integrated option. For this 131mm stroke, ensure guide rails carry side loads to prevent rod bending. A plain cylinder drifts without air; add a pilot-operated check valve for load holding. Finally, swap your CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors.
Replacement checklist
- ✓ Same bore / stroke → SAU63X131S
- ✓ 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 SU63X131S FAQ
Yes, the SU63X131S is end-of-life. The direct replacement is the AirTAC SAU63X131S. It matches the 63mm bore, 131mm stroke, 1559N output force at 0.5MPa, 3/8" port, and SC-series mounting accessories. You can install the SAU directly into the same application.
The 63mm bore provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
