This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X80STC, 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 SU63X80STC
The AirTAC SU63-100 Standard Cylinder SU63X80STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X80STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X80STC
The AirTAC SU63X80STC is a discontinued double-acting profile-type cylinder with an 80 mm stroke and 63 mm bore. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X80STC, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade switches the -S magnet sensor compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M solenoid valve variant the SU line lacked. Note that standard air cushions only decelerate the piston; they do not hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X80STC 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 SAU63X80STC 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 SU63X80STC Is Used
Carton Diverting
Pushes medium-weight packages at 30-800 mm/s on packaging lines, utilizing the 1559 N thrust to redirect items smoothly without rebound.
Pallet Stopper
Acts as a robust end-stop for inbound pallets, where the TC mount secures the body and the 80 mm stroke absorbs kinetic energy.
Replacing the Airtac SU63-100 Standard Cylinder SU63X80STC with the SAU63X80STC
To replace this discontinued SU63X80STC, order the SAU63X80STC, confirming the 63 mm bore, 80 mm stroke, 3/8" port, M16x1.5 rod thread, and TC mounting interface. Because this SKU includes the -S magnet, you must upgrade your sensors: legacy CS1-B/DS1-B switches will not fit the SAU groove, so use CMSG/DMSG/EMSG sensors instead. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N. For load holding on vertical applications, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate. If you need integrated flow control, explore the SAUF variant with its built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X80STC
- ✓ 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 SU63X80STC FAQ
Yes, the SU63X80STC is discontinued. The direct replacement is the AirTAC SAU63X80STC. It matches the 63 mm bore, 80 mm stroke, 3/8" port, 1559 N force, and SC-series TC mounting, fitting the same space without modifications.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. The -S magnet on this legacy model works with CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
