This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X180, 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 SU63X180
The AirTAC Airtac SU63-100 Standard Cylinder SU63X180 is a double-acting profile-type standard cylinder with a Ø63mm bore and 180mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X180, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X180
The AirTAC SU63X180 is a discontinued double-acting profile cylinder with a 63 mm bore and 180 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X180, a direct replacement retaining the exact bore, stroke, output force, port size and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade switches to current CMSG/DMSG/EMSG switches and adds an optional SAUF built-in valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X180 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 SAU63X180 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 SU63X180 Is Used
Package Diverting
Pushes cartons at 90 degrees on a packing line using the 1559 N push force at 0.5 MPa to reliably overcome side friction.
Pallet Stop Gate
Acts as a pneumatic stop for incoming pallets, absorbing kinetic energy via the 21 mm adjustable air cushions at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X180 with the SAU63X180
To replace the SU63X180, order the SAU63X180 with the same 63 mm bore, 180 mm stroke, 3/8" port, M16x1.5 rod thread and SC-series mounting. Since this specific SKU has no magnet (-S), it cannot support sensing; if you need position detection on the SAU, you must select the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At 180 mm, side-load risks are low, but always guide the load to prevent rod bending. If you need higher force, the 80 mm bore offers 2513 N push at 0.5 MPa; if you need less, the 50 mm bore provides 982 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF variant integrates a 4M valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X180
- ✓ 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 SU63X180 FAQ
Yes, the SU63X180 is discontinued. The direct replacement is the AirTAC SAU63X180. It matches the 63 mm bore, 180 mm stroke, output force, 3/8" port and SC-series mounting, so it fits the same application directly.
It provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf theoretical max at 1.0 MPa. Because this SKU lacks a magnet, it cannot take a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
