This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X750SH, 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 SU80X750SH
The AirTAC SU63-100 Standard Cylinder SU80X750SH is a double-acting profile-type standard cylinder with a Ø80mm bore and 750mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X750SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X750SH
The AirTAC SU80X750SH is a discontinued double-acting profile cylinder with an 80 mm bore, 750 mm stroke, Viton H high-temperature seals, and a piston magnet. It delivers 2513 N push and 2268 N pull at 0.5 MPa. AirTAC replaced this unit with the SAU80X750SH, a direct replacement retaining the exact bore, stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting compatibility.
When upgrading, note the SAU replacement uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors on this SU model. The SAU line also introduces a SAUF valve-integrated variant the SU series lacked.

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 SAU80X750SH 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 SU80X750SH Is Used
High-Temp Material Transfer
Ideal for pushing heavy parts or diverting goods on a conveyor in heated zones, utilizing the Viton H seal to withstand ambient temperatures up to 150 C without degrading.
Extended Reach Ejection
The 750 mm stroke provides the long travel necessary to eject molded components or clear large machinery envelopes, guided externally to prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU80X750SH with the SAU80X750SH
To replace this discontinued SU80X750SH, order the SAU80X750SH direct equivalent, verifying your 3/8" port, M20x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes a magnet (-S), you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. The Viton H seal provides 0-150 C heat resistance. If sizing alternatives, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. A plain cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for safety. At 750 mm stroke, prevent rod bending by supporting the load with an external guide to minimize side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X750SH
- ✓ 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 SU80X750SH FAQ
Yes, the AirTAC SU80X750SH is discontinued and end-of-life. The direct replacement is the SAU80X750SH. It features the same 80 mm bore, 750 mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
This 80 mm bore cylinder outputs 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Because this model has a magnet (-S) for legacy CS1-B/DS1-B switches, upgrading to the SAU replacement requires switching to current CMSG/DMSG/EMSG sensors.
