This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X550, 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 SU80X550
The AirTAC Airtac SU63-100 Standard Cylinder SU80X550 is a double-acting profile-type standard cylinder with a Ø80mm bore and 550mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X550, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X550
The AirTAC SU80X550 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 550 mm stroke. Built with an extruded aluminium barrel, it is more compact than an ISO 15552 cylinder of the same bore while delivering a robust 2513 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU80X550, a direct upgrade retaining the exact 3/8" port, M20x1.5 rod thread, 513 kgf max force and SC-series mounting.
Because this specific SKU lacks a magnet, it cannot accept a position sensor. If sensing is required, the SAU replacement features a modern groove for CMSG/DMSG/EMSG switches, whereas the legacy SU line used older CS1-B/DS1-B rails. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X550 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 SAU80X550 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 SU80X550 Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using 2513 N of thrust at 0.5 MPa, with the 550 mm stroke clearing wide transport lanes.
Material Ejection
Kicks finished machined parts out of a CNC workstation, using the 28 mm adjustable air cushions to decelerate the 80 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X550 with the SAU80X550
To replace the discontinued SU80X550, order the SAU80X550 direct equivalent, verifying your 3/8" port, M20x1.5 rod thread and SC-series mounting hardware (LB, FA, FB, CA, CB). This non-magnetic SKU cannot support switches; if you need sensing, the SAU upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. When sizing, note the neighbouring 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N, allowing you to step up or down if your application has changed. A plain cylinder drifts without live air—the 28 mm adjustable cushions only decelerate near stroke end, so add an external rod lock or pilot-operated check valve for secure load holding. Finally, the 550 mm stroke demands external guiding to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X550
- ✓ 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 SU80X550 FAQ
Yes, the AirTAC SU80X550 is discontinued. The direct replacement is the SAU80X550, which shares the identical 80 mm bore, 550 mm stroke, 3/8" port, 513 kgf max force and SC-series mounting accessories.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf theoretical max at 1.0 MPa. Because this SKU has no magnet, it cannot take a sensor; the SAU replacement supports CMSG/DMSG/EMSG switches.
