This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1700STC, 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 SU80X1700STC
The AirTAC SU63-100 Standard Cylinder SU80X1700STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 1700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1700STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1700STC
The AirTAC SU80X1700STC is a discontinued double-acting profile-type cylinder with an extruded aluminum barrel and adjustable air cushions. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. Because this 1700 mm stroke exceeds the 1500 mm standard maximum for the 80 mm bore, it is a non-standard, made-to-order unit. AirTAC replaced the SU line with the SAU family; the direct replacement is the SAU80X1700STC, matching the exact bore, stroke, force, port, and SC-series mounting.
The SAU upgrade keeps the compact profile body but switches the -S magnet compatibility from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. It also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1700STC 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 SAU80X1700STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X1700STC
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×1700 | Stroke length in mm. |
| -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 SU80X1700STC Is Used
Long-Reach Material Push
Ideal for extending across wide conveyor belts to push heavy pallets or workpieces, utilizing the 2513 N push force at 0.5 MPa over a 1700 mm travel distance.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1700STC with the SAU80X1700STC
To replace the discontinued SU80X1700STC, order the SAU80X1700STC. Verify your 3/8" port, M20x1.5 rod thread, TC mounting interface, and PT thread type. Because the 1700 mm stroke exceeds the 1500 mm standard maximum, expect a made-to-order lead time and ensure external guides are used to prevent rod bending over this long distance. If sizing down, a 63 mm bore provides 1559 N push at 0.5 MPa; if sizing up, a 100 mm bore yields 3927 N. Note that the -S magnet requires switching to CMSG/DMSG/EMSG sensors on the SAU. A plain cylinder does not hold load without live air; the cushion only decelerates, so add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1700STC
- ✓ 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 SU80X1700STC FAQ
Yes, the SU80X1700STC is discontinued. The direct replacement is the SAU80X1700STC. It shares the same 80 mm bore, 1700 mm stroke, 3/8" port, output force, and SC-series TC mounting. Note that the 1700 mm stroke is non-standard and made-to-order.
The cylinder provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. The SAU replacement retains the -S magnet but requires upgrading from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
