This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X120TC, 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 SU80X120TC
The AirTAC SU63-100 Standard Cylinder SU80X120TC is a double-acting profile-type standard cylinder with a Ø80mm bore and 120mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X120TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X120TC
The AirTAC SU80X120TC is a discontinued double-acting profile-type cylinder with an 80mm bore and 120mm stroke. It delivers 2513N push force at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU80X120TC, a direct upgrade retaining the exact bore, stroke, output force, and SC-series TC mounting interface.
Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches (the legacy line used CS1-B/DS1-B). The SAU family also adds a SAUF variant with a built-in 4M solenoid valve.

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 SAU80X120TC 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 SU80X120TC Is Used
Pallet Diversion
Uses the 2513N push force at 0.5MPa to reliably deflect heavy pallets onto secondary conveyor lines without mechanical hesitation.
Container Ejection
Leverages the 120mm stroke and 128kg safe vertical lift capacity to push loaded totes from packaging stations onto takeaway rollers.
Press Ejection
Fits into compact machinery via the extruded aluminum profile body, providing positive part ejection from forming dies using the TC mount.
Replacing the Airtac SU63-100 Standard Cylinder SU80X120TC with the SAU80X120TC
To replace this SU80X120TC, order the SAU80X120TC. Confirm the 80mm bore, 120mm stroke, 3/8" port, M20x1.5 rod thread, and TC mounting accessory are correct for your machine. Sizing context: dropping to a 63mm bore yields 1559N push at 0.5MPa, while an 80mm bore provides 2513N. This non-magnetic SKU cannot support switches; if you need position sensing, order an SAU with an -S suffix and use CMSG/DMSG/EMSG sensors. For intermediate stops, note that air cushions only decelerate; they do not hold loads. Use an external rod lock or pilot-operated check valve for secure holding. If your cycle demands faster actuation, the SAUF valve-integrated option is worth exploring.
Replacement checklist
- ✓ Same bore / stroke → SAU80X120TC
- ✓ 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 SU80X120TC FAQ
Yes, the SU80X120TC is discontinued. The direct replacement is the SAU80X120TC. It shares the identical 80mm bore, 120mm stroke, 2513N force, 3/8" port, and TC mounting, so it drops right into the same profile body footprint.
At 0.5MPa it pushes 2513N and pulls 2268N. At 0.7MPa push is 3518N, and at 0.9MPa it is 4523N. The theoretical maximum is 513kgf at 1.0MPa. The 28mm adjustable air cushions only decelerate the piston near stroke ends; they do not hold loads. For secure load holding on air loss, use an external rod lock or pilot-operated check valve.
