This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X310S, 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 SU80X310S
The AirTAC SU63-100 Standard Cylinder SU80X310S is a double-acting profile-type standard cylinder with a Ø80mm bore and 310mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X310S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X310S
The AirTAC SU80X310S is a discontinued double-acting profile-type cylinder featuring an extruded aluminum barrel and a built-in piston magnet. Delivering 2513 N of push force at 0.5 MPa, it utilizes a 3/8 inch port and a 25 mm piston rod. AirTAC replaced this legacy unit with the SAU80X310S, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
When upgrading to the SAU80X310S, the body and cushioning remain unchanged, but the sensor family transitions from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. Furthermore, the SAU platform introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU line never offered.

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 SAU80X310S 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 SU80X310S Is Used
Pallet Diversion
Actuates heavy diverters on packaging lines, using the 2513 N push force to redirect loaded pallets reliably at speed.
Press Ejection
Ejects formed metal components from stamping presses, utilizing adjustable end cushions to decelerate the 25 mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X310S with the SAU80X310S
To replace the SU80X310S, order the SAU80X310S and verify the 80 mm bore, 310 mm stroke, 3/8 inch port, M20x1.5 rod thread, and PT/G/NPT thread preference. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the SAU model. If sizing alternatives, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. For any stroke of 310 mm or more, utilize external guides to prevent rod bending and mitigate side loads. A plain cylinder will not hold a load without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve for secure holding. If valve integration is desired, consider the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU80X310S
- ✓ 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 SU80X310S FAQ
Yes, the SU80X310S is discontinued. The direct replacement is the SAU80X310S, which matches the 80 mm bore, 310 mm stroke, 2513 N force, 3/8 inch port, and SC-series mounting.
The bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Because this is an -S model, the legacy CS1-B/DS1-B sensors are replaced by CMSG/DMSG/EMSG switches on the SAU upgrade.
