This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X50STC, 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 SU80X50STC
The AirTAC Airtac SU63-100 Standard Cylinder SU80X50STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X50STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X50STC
The AirTAC SU80X50STC is a discontinued double-acting profile-type cylinder with an 80mm bore, 50mm stroke, and a 3/8" port. It delivers 2513 N of push force at 0.5 MPa. AirTAC replaced this unit with the SAU80X50STC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S SKU, and adds the SAUF built-in 4M solenoid valve option the SU line lacked. The extruded aluminum body is more compact than a same-bore ISO 15552 cylinder.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X50STC 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 SAU80X50STC 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 SU80X50STC Is Used
Package Diverting
Drives a short 50mm stroke diverter arm on a packaging line, utilizing the 80mm bore's 2513 N push force to reliably redirect heavy cartons at high speed.
Clamping Station
Secures heavy steel workpieces in a machining fixture, where the compact extruded profile saves space while delivering a 1508 N safe working clamping load.
Pallet Stopper
Acts as a robust pneumatic stop for incoming pallets on a TC-mounted conveyor bracket, absorbing kinetic energy through its adjustable 28mm end cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X50STC with the SAU80X50STC
To replace this SU80X50STC, order the SAU80X50STC. Verify your 80mm bore, 50mm stroke, 3/8" port, M20x1.5 rod thread, and TC mounting. Because this model has the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If your machine needs higher force, the 100mm bore offers 3927 N push at 0.5 MPa; if less is needed, the 63mm bore provides 1559 N. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X50STC
- ✓ 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 SU80X50STC FAQ
Yes, the AirTAC SU80X50STC is discontinued. The direct replacement is the SAU80X50STC. It shares the identical 80mm bore, 50mm stroke, 3/8" port, output force, and SC-series TC mounting, so it fits the same application directly.
This 80mm bore cylinder delivers 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. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
