This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X505S, 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 SU80X505S
The AirTAC SU63-100 Standard Cylinder SU80X505S is a double-acting profile-type standard cylinder with a Ø80mm bore and 505mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X505S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X505S
The AirTAC SU80X505S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 505 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf. AirTAC replaced this end-of-line unit with the SAU80X505S, a direct upgrade retaining the exact bore, stroke, force, 3/8" port, and SC-series mounting.
This extruded aluminium body is shorter than an ISO 15552 cylinder of the same size. The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches; the SAU replacement uses modern CMSG/DMSG/EMSG sensors and adds a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X505S 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 SAU80X505S 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 SU80X505S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using a robust 80 mm bore yielding 2513 N at 0.5 MPa.
Press Ejection
Ejects dense stamped metal parts from a press bed, relying on adjustable 28 mm cushions to brake the rod.
Replacing the Airtac SU63-100 Standard Cylinder SU80X505S with the SAU80X505S
To replace this SU80X505S, order the SAU80X505S direct equivalent, verifying the 80 mm bore, 505 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting. 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 neighbouring 100 mm bore offers 3927 N push at 0.5 MPa; if lower force is acceptable, the 63 mm bore provides 1559 N. A plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. At 505 mm stroke, prevent rod bending by supporting the load with an external guide to avoid side-loading. The SAUF variant integrates a 4M solenoid valve if self-switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU80X505S
- ✓ 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 SU80X505S FAQ
Yes, the SU80X505S is discontinued. The direct replacement is the SAU80X505S. It shares the identical 80 mm bore, 505 mm stroke, output force, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and the theoretical max is 513 kgf at 1.0 MPa. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades these to CMSG/DMSG/EMSG sensors.
