This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X700STC, 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 SU80X700STC
The AirTAC Airtac SU63-100 Standard Cylinder SU80X700STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X700STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X700STC
The AirTAC SU80X700STC is a discontinued double-acting profile-type cylinder with an 80 mm bore and 700 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU80X700STC, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting interface.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches, and introduces the SAUF built-in-valve variant. Because the 700 mm stroke is long, use external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X700STC 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 SAU80X700STC 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 SU80X700STC Is Used
Heavy Material Transfer
Drives heavy pallets along a 700 mm stroke on a packaging conveyor, utilizing the 2513 N push force at 0.5 MPa to shift loads reliably without requiring maximum system pressure.
Long-Stroke Assembly Press
Executes 700 mm extension strokes to position large automotive sub-components, depending on external guides to prevent rod bending during the extended cycle.
Replacing the Airtac SU63-100 Standard Cylinder SU80X700STC with the SAU80X700STC
To replace the SU80X700STC, order the SAU80X700STC. Verify your 80 mm bore, 700 mm stroke, 3/8" port, M20x1.5 rod thread, and TC mounting accessory. This unit includes a piston magnet (-S); note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If sizing neighbours, the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for held loads. Finally, the 700 mm stroke requires external guides to manage rod-bending side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X700STC
- ✓ 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 SU80X700STC FAQ
Yes, the SU80X700STC is discontinued. The direct replacement is the AirTAC SAU80X700STC. It matches the 80 mm bore, 700 mm stroke, 2513 N force, 3/8" port, and TC mounting, so it drops right into the same application.
The 80 mm bore yields 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 SKU has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
