This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1090S, 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 SU63X1090S
The AirTAC SU63-100 Standard Cylinder SU63X1090S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1090mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1090S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1090S
The AirTAC SU63X1090S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 1090 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X1090S, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting.
Because this is a nonstandard stroke exceeding the 1500 mm limit, note the 1090 mm length demands external guide support to prevent rod bending. The SAU upgrade switches the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches and introduces the SAUF built-in-valve option.

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 SAU63X1090S 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 SU63X1090S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along a 1090 mm conveyor section using the 1559 N thrust at 0.5 MPa, requiring external guides to support the extended rod.
High-Reach Stacking Pusher
Elevates goods to upper tiers with a safe vertical lift capacity of 79 kg, relying on the magnetic position feedback for reliable cycle counts.
Automated Assembly Line Indexing
Drives large tooling carriages across a wide machine bed, benefiting from the compact profile body and 3/8" port for rapid actuation.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1090S with the SAU63X1090S
To replace this discontinued SU63X1090S, order the SAU63X1090S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the CMSG/DMSG/EMSG family. At 1090 mm, this long cylinder requires external guides to prevent rod bending under side loads. For sizing both ways: a 50 mm bore provides 982 N push at 0.5 MPa (too small), while an 80 mm bore yields 2513 N. If you need intermediate stopping, consider the SAUF variant with its built-in 4M solenoid valve. Remember, a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for secure load holding, as the adjustable cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1090S
- ✓ 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 SU63X1090S FAQ
Yes, the SU63X1090S is discontinued. The direct replacement is the AirTAC SAU63X1090S. It matches the original 63 mm bore, 1090 mm stroke, 3/8" port, output force, and SC-series mounting accessories. You simply order the SAU63X1090S as a direct fit.
This double-acting cylinder provides 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. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
