This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X35S, 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 SU80X35S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X35S is a double-acting profile-type standard cylinder with a Ø80mm bore and 35mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X35S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X35S
The AirTAC SU80X35S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 35 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced it with the SAU80X35S, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade transitions the -S magnet to modern CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X35S 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 SAU80X35S 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 SU80X35S Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping of heavy steel plates in machining fixtures, utilizing the compact 35 mm stroke to secure parts rapidly.
Package Diverting
Provides robust actuation for diverting heavy pallets or bulk totes on a conveyor line, where the 80 mm bore ensures reliable pushing power.
Pallet Stopping
Acts as a heavy-duty end-stop in automated storage systems, decelerating incoming 100+ kg loads using the adjustable 28 mm air cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X35S with the SAU80X35S
To replace this SU80X35S, order the SAU80X35S by confirming the 80 mm bore, 35 mm stroke, 3/8" port, and M20x1.5 rod thread. Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the 100 mm bore offers 3927 N push at 0.5 MPa; for less, the 63 mm bore provides 1559 N. This plain cylinder will not hold a load without live air—the 28 mm adjustable cushions only decelerate—so add an external rod lock or pilot-operated check valve for secure holding. The SAU line also adds a SAUF variant with a built-in 4M solenoid valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU80X35S
- ✓ 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 SU80X35S FAQ
Yes, the SU80X35S is discontinued. The direct replacement is the AirTAC SAU80X35S. It matches the 80 mm bore, 35 mm stroke, 2513 N force, 3/8" port, and SC-series mounting. You must upgrade your -S magnet sensors from the old CS1-B/DS1-B to the new CMSG/DMSG/EMSG family.
The 80 mm bore uses a fixed 3/8" port. At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa, operating at 30-800 mm/s.
