This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X630S, 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 SU80X630S
The AirTAC SU63-100 Standard Cylinder SU80X630S is a double-acting profile-type standard cylinder with a Ø80mm bore and 630mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X630S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X630S
The AirTAC SU80X630S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 630 mm stroke. It delivers 2513 N push force at 0.5 MPa and features a 3/8" port. The direct replacement is the SAU80X630S, which preserves the bore, stroke, force, port and SC-series mounting.
When upgrading, note the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. The SAUF variant also adds a built-in valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X630S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X630S 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 SU80X630S Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways across a 630 mm gap using the 2513 N push force at 0.5 MPa, requiring external guides to prevent rod bending.
Heavy Press Assembly
Provides steady 3518 N thrust at 0.7 MPa to seat large bearings, with adjustable 28 mm cushions absorbing end-of-stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X630S with the SAU80X630S
To replace this SU80X630S, order the SAU80X630S ensuring your 3/8" port, M20x1.5 rod thread and SC-series mounting match. Because this has a 630 mm stroke, use external guides to prevent rod bending under side loads. For higher force, the 100 mm bore offers 3927 N [email protected]; for less, the 63 mm bore gives 1559 N. The magnet (-S) means you must switch from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. The cushion only decelerates; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X630S
- ✓ 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 SU80X630S FAQ
Yes, the SU80X630S is discontinued. The direct replacement is the SAU80X630S. It matches the 80 mm bore, 630 mm stroke, 2513 N force, 3/8" port and SC-series mounting. You just order the SAU equivalent.
The SAU80X630S matches the SU force ratings: 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf max at 1.0 MPa. The SAU replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
