This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X90, 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 SU100X90
The AirTAC Airtac SU63-100 Standard Cylinder SU100X90 is a double-acting profile-type standard cylinder with a Ø100mm bore and 90mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X90, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X90
The AirTAC SU100X90 is a discontinued double-acting profile cylinder, delivering 3927 N push and 3681 N pull at 0.5 MPa through its 100 mm bore. AirTAC replaced this end-of-line unit with the SAU100X90, a direct alternative retaining the exact 90 mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept position switches. The SAU upgrade introduces CMSG/DMSG/EMSG sensor compatibility and a SAUF built-in 4M solenoid valve option the SU line never had. The 29 mm adjustable cushions decelerate loads but do not lock them without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X90 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X90 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 SU100X90 Is Used
Heavy Press Operations
Drives high-force stamping and forming presses where 3927 N at 0.5 MPa is required to shape metal components securely.
Pallet Dispensing
Pushes heavy loaded pallets in automated distribution lines, utilizing the 90 mm stroke for rapid, repetitive actuation.
Mold Clamping Stations
Secures industrial molds and heavy fixtures during manufacturing, benefiting from the 25 mm piston rod rigidity.
Replacing the Airtac SU63-100 Standard Cylinder SU100X90 with the SAU100X90
To replace the SU100X90, order the SAU100X90 after verifying your 1/2" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB). Since this specific SKU has no magnet, you cannot mount legacy CS1-B/DS1-B switches; if sensing is needed, the SAU replacement requires current CMSG/DMSG/EMSG sensors. If your application needs integrated flow control, explore the SAUF variant with its built-in valve. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If downsizing from 100 mm, a 80 mm bore yields 2513 N push at 0.5 MPa; if upsizing, note 100 mm is the largest available.
Replacement checklist
- ✓ Same bore / stroke → SAU100X90
- ✓ 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 SU100X90 FAQ
Yes, the SU100X90 is discontinued. The direct replacement is the AirTAC SAU100X90, which matches the 100 mm bore, 90 mm stroke, 1/2" port, and SC-series mounting. The SAU body is fully compatible, though it upgrades sensor compatibility to CMSG/DMSG/EMSG switches.
This double-acting cylinder features a 1/2" port. It generates 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
