This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X170, 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 SU80X170
The AirTAC Airtac SU63-100 Standard Cylinder SU80X170 is a double-acting profile-type standard cylinder with a Ø80mm bore and 170mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X170, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X170
The AirTAC SU80X170 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 170 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU80X170, a direct upgrade retaining the exact body dimensions, output force, and SC-series mounting accessories.
This non-magnetic SKU cannot accept a sensor, whereas the SAU upgrade supports modern CMSG/DMSG/EMSG switches. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a feature the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X170 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 SAU80X170 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 SU80X170 Is Used
Pallet Diversion
Provides the robust push force needed to redirect heavy pallets onto secondary packaging lines without requiring external guidance.
Material Ejection
Ideal for pushing completed goods or dunnage off accumulation rollers at mid-stroke distances in automated distribution hubs.
Press Ejection
Delivers reliable knock-out force to eject dense metal or composite parts from lower-pressure press dies.
Replacing the Airtac SU63-100 Standard Cylinder SU80X170 with the SAU80X170
To replace this discontinued SU80X170, order the SAU80X170. Verify your 3/8" port thread (PT, G, or NPT), M20x1.5 rod-end connection, and SC-series mounting hardware, as these remain identical. Because this specific SKU lacks a magnet (-S), it cannot support position sensing; if your application requires switches, select an SAU model with the -S option and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B types. If you need integrated flow control, explore the SAUF variant with its built-in valve. When sizing alternatives, consider the 63 mm bore (1559 N push @0.5 MPa) for lighter loads or the 100 mm bore (3927 N push @0.5 MPa) for heavier demands. Remember that a standard cylinder does not hold load without live air; the adjustable 28 mm cushions only decelerate the piston near stroke end. For suspended or vertical loads, install an external rod lock or pilot-operated check valve to prevent drift.
Replacement checklist
- ✓ Same bore / stroke → SAU80X170
- ✓ 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 SU80X170 FAQ
Yes, the SU80X170 is discontinued. The direct replacement is the AirTAC SAU80X170. It shares the identical 80 mm bore, 170 mm stroke, 2513 N output force at 0.5 MPa, 3/8" port size, and SC-series mounting footprint, so it fits your existing assembly directly.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. This specific SKU has no magnet and cannot accept a sensor. If sensing is required, the SAU replacement with the -S option uses current CMSG/DMSG/EMSG switches.
