This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X500SCA, 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 SU63X500SCA
The AirTAC Airtac SU63-100 Standard Cylinder SU63X500SCA is a double-acting profile-type standard cylinder with a Ø63mm bore and 500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X500SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X500SCA
The AirTAC SU63X500SCA is a discontinued double-acting profile-type cylinder with a 63mm bore and 500mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, operating via a 3/8" port. AirTAC replaced this end-of-line unit with the SAU63X500SCA, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series CA mounting interface.
The SAU upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M solenoid valve variant the SU line lacked. The extruded aluminium body remains shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X500SCA 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 SAU63X500SCA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×500 | 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 SU63X500SCA Is Used
Pallet Diversion
Pushes heavy pallets sideways at 1559N push force, utilizing the 500mm stroke to clear the main conveyor path completely.
Material Ejection
Ejects molded parts from a press using the CA clevis mount to accommodate angular movement during the 500mm extension.
Replacing the Airtac SU63-100 Standard Cylinder SU63X500SCA with the SAU63X500SCA
To replace this SU63X500SCA, order the SAU63X500SCA and verify the 63mm bore, 500mm stroke, 3/8" port, M16x1.5 rod thread, and CA mount. Because this SKU includes the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: a 50mm bore yields 982N push, while an 80mm bore yields 2513N push at 0.5MPa. For the 500mm stroke, use an external guide to prevent rod-bending under side loads. The air cushion only decelerates; for load holding on air loss, install an external rod lock or pilot-operated check valve. The SAUF valve-integrated option can simplify cycling if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X500SCA
- ✓ 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 SU63X500SCA FAQ
Yes, the SU63X500SCA is discontinued. The direct replacement is the SAU63X500SCA, which matches the 63mm bore, 500mm stroke, 3/8" port, output force, and SC-series CA mounting.
It provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. Because this model has the -S magnet, it used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
