This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X125N, 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 SU80X125N
The AirTAC SU63-100 Standard Cylinder SU80X125N is a double-acting profile-type standard cylinder with a Ø80mm bore and 125mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X125N, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X125N
The AirTAC SU80X125N is a discontinued double-acting profile-type cylinder with an 80 mm bore and 125 mm stroke. It delivers 2513 N push force at 0.5 MPa. AirTAC replaced it with the SAU80X125N, a direct upgrade retaining the exact bore, stroke, output force, 3/8" port, and SC-series mounting. This NBR-sealed unit operates from -20 to +70 C.
Because it lacks a magnet, this SKU cannot accept a sensing switch. The SAU successor also omits one, though if you ever needed sensors you would use the current CMSG/DMSG/EMSG family rather than the legacy CS1-B/DS1-B. The SAU line also adds a SAUF valve-integrated variant the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X125N 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 SAU80X125N 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 SU80X125N Is Used
Pressing and Forming
Clamping metal workpieces in light-duty presses, using the 2513 N push force at 0.5 MPa for secure holding during deformation.
Heavy Package Diversion
Actuating large deflectors on packaging lines to route heavy cartons, benefiting from the compact profile body and 125 mm stroke.
Pallet Stop Gates
Raising and lowering stop gates at conveyor ends to accumulate pallets, relying on the 3/8" port for rapid actuation.
Replacing the Airtac SU63-100 Standard Cylinder SU80X125N with the SAU80X125N
To replace this SU80X125N, order the SAU80X125N. Confirm the 80 mm bore, 125 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting are identical. This non-magnetic SKU cannot take a switch; if sensing is ever needed, the SAU uses CMSG/DMSG/EMSG switches. The NBR seal suits standard temps (-20 to +70 C); choose Viton H for up to 150 C. For loads needing 4523 N at 0.9 MPa, this 80 mm bore is ideal, whereas stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. Note: a plain cylinder drifts on air loss—the cushion only decelerates, so use an external rod lock for holding. The SAUF variant adds a built-in valve if desired.
Replacement checklist
- ✓ Same bore / stroke → SAU80X125N
- ✓ 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 SU80X125N FAQ
Yes, the SU80X125N is discontinued. The direct replacement is the SAU80X125N, which shares the identical 80 mm bore, 125 mm stroke, 2513 N force, 3/8" port, and SC-series mounting.
It provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. This specific -N SKU has no magnet and cannot accept a sensor; if sensing were added on the SAU replacement, it uses CMSG/DMSG/EMSG switches.
