This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1320S, 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 SU63X1320S
The AirTAC SU63-100 Standard Cylinder SU63X1320S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1320mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1320S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1320S
The AirTAC SU63X1320S is a discontinued double-acting profile cylinder with a 63 mm bore and 1320 mm stroke. Because 1320 mm exceeds the 1500 mm max standard stroke threshold for this bore, it is flagged as a nonstandard stroke. It delivers 1559 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU63X1320S, a direct upgrade retaining the exact bore, stroke, output force, 3/8 inch port, and SC-series mounting.
The SAU replacement upgrades the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG family, and introduces the SAUF built-in 4M valve option the SU line lacked. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1320S 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 SAU63X1320S 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 SU63X1320S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along a 1.3-meter conveyor line, utilizing the 1559 N push force at 0.5 MPa to overcome friction over the extended travel distance.
High-Reach Stowage Arm
Actuates a 1320 mm reach arm for depositing goods onto upper storage tiers, requiring external guides to manage the long rod side-load.
Large Panel Indexing
Shifts wide fabrication panels between machining stations, relying on the 63 mm bore's 1402 N pull force to retract the extended tooling.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1320S with the SAU63X1320S
To replace this SU63X1320S, order the SAU63X1320S direct equivalent, verifying the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware. If your bore 63 mm is too weak, step up to an 80 mm (2513 N push at 0.5 MPa); if too strong, step down to a 50 mm (982 N). Because the 1320 mm stroke exceeds standard lengths, it requires nonstandard handling, and at this length you must use external guides to prevent rod bending and side-load damage. The -S magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG on the SAU. For load holding on air loss, add a pilot-operated check valve or external rod lock, as cushions only decelerate. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1320S
- ✓ 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 SU63X1320S FAQ
Yes, the SU63X1320S is discontinued. The direct replacement is the AirTAC SAU63X1320S. It matches the 63 mm bore, 1320 mm stroke, force, 3/8 inch port, and SC-series mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. Push is 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, with a 318 kgf max at 1.0 MPa. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
