This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X120, 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 SU63X120
The AirTAC Airtac SU63-100 Standard Cylinder SU63X120 is a double-acting profile-type standard cylinder with a Ø63mm bore and 120mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X120, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X120
The AirTAC SU63X120 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 120 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X120, a direct upgrade retaining the exact bore, stroke, output, and SC-series mounting footprint.
Because the extruded aluminum profile body omits external rods, it is more compact than a same-bore ISO 15552 unit. Note this non-magnetized SKU cannot accept a sensor; the SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X120 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 SAU63X120 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU63X120 Is Used
Package Diverting
Drives diverter arms on packaging lines where 1559 N push at 0.5 MPa easily redirects heavy cartons without bouncing.
Clamp Actuation
Secures heavy steel workpieces during machining, utilizing the 1402 N pull force to hold components firmly against stops.
Pallet Stopping
Deploys robust stop gates in pallet conveyors, absorbing kinetic energy via 21 mm adjustable air cushions at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X120 with the SAU63X120
To replace this SU63X120, order the SAU63X120. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are unchanged. This non-magnetized SKU cannot take a switch; if you need position sensing, step up to an SAU-S model which uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. If sizing alternatives, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushions only decelerate. At 120 mm stroke, side-load is minimal, but ensure adequate guidance on longer strokes.
Replacement checklist
- ✓ Same bore / stroke → SAU63X120
- ✓ 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 SU63X120 FAQ
Yes, the SU63X120 is discontinued. The direct replacement is the AirTAC SAU63X120. It shares the identical 63 mm bore, 120 mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
It 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. This specific SKU lacks a magnet and cannot accept a sensor. If sensing is needed, the SAU replacement with the -S option uses CMSG/DMSG/EMSG switches.
