This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X15S, 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 SU80X15S
The AirTAC SU63-100 Standard Cylinder SU80X15S is a double-acting profile-type standard cylinder with a Ø80mm bore and 15mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X15S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X15S
The AirTAC SU80X15S is a discontinued double-acting profile-type cylinder with an extruded aluminum barrel and adjustable air cushions at both ends. It delivers 2513 N push and 2268 N pull at 0.5 MPa, utilizing a 25 mm piston rod and a 3/8" port. AirTAC replaced this legacy unit with the SAU80X15S, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series mounting compatibility.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, superseding the older CS1-B/DS1-B switches used on this -S magnet model, and adds a new SAUF built-in 4M solenoid valve option the SU line lacked. The compact profile body is inherently shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X15S 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 SAU80X15S 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 SU80X15S Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping of heavy steel plates in machining fixtures where a compact 15 mm stroke securely locks the part without extending into the work zone.
Heavy Diverting
Provides robust 80 mm bore push force to divert heavy pallets or bulk material boxes on a conveyor line, utilizing the compact profile to fit within tight transfer station frames.
Pallet Stops
Acts as a heavy-duty pneumatic stop gate in automated storage systems, raising a 25 mm rod to halt 128 kg vertical or horizontal pallet loads reliably at 0.5 MPa.
Replacing the Airtac SU63-100 Standard Cylinder SU80X15S with the SAU80X15S
To replace the SU80X15S, order the SAU80X15S direct equivalent, verifying the 80 mm bore, 15 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes a magnet (-S), note that the legacy CS1-B/DS1-B switches must be replaced by current CMSG/DMSG/EMSG sensors on the SAU model. Sizing both ways: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N, allowing you to scale if application forces change. A plain cylinder does not hold load without live air; the cushions only decelerate, so use an external rod lock or pilot-operated check valve for vertical hold. The 15 mm stroke is very short, so side-load risks are minimal, but ensure precise rod alignment to avoid binding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X15S
- ✓ 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 SU80X15S FAQ
Yes, the AirTAC SU80X15S is discontinued. The direct replacement is the SAU80X15S. It shares the identical 80 mm bore, 15 mm stroke, 2513 N output force, 3/8" port, and SC-series mounting, so it drops directly into the same application. The SAU body also introduces a built-in 4M solenoid valve option (SAUF variant) that the SU line never offered.
The SAU80X15S matches the SU force ratings exactly: 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 your original model has a magnet (-S), you must upgrade the sensors: the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family on the SAU cylinder.
