This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X850, 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 SU63X850
The AirTAC Airtac SU63-100 Standard Cylinder SU63X850 is a double-acting profile-type standard cylinder with a Ø63mm bore and 850mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X850, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X850
The AirTAC SU63X850 is a discontinued double-acting profile-type cylinder with an 850 mm stroke and 63 mm bore. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this EOL unit with the SAU63X850, a direct upgrade retaining the exact bore, stroke, force, port and SC-series mounting.
The SAU body is shorter than an ISO 15552 cylinder of the same bore. This base SU63X850 lacks a magnet and cannot accept sensors, whereas the SAU upgrade supports modern CMSG/DMSG/EMSG switches and even a SAUF built-in valve option.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X850 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 SU63X850 Is Used
Long-Stroke Diverting
Pushes packages across a 850 mm transfer lane, utilizing the 1559 N push force at 0.5 MPa to overcome friction on heavy pallets.
Automated Assembly Ejection
Ejects completed assemblies from a machine bed, relying on adjustable 21 mm cushions to decelerate the payload at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU63X850 with the SAU63X850
To replace this SU63X850, order the SAU63X850 direct equivalent, confirming the 63 mm bore, 850 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this specific SKU has no magnet (-S), it cannot accept a position switch; if sensing is needed, the SAU replacement allows adding CMSG/DMSG/EMSG sensors. Sizing both ways: a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. For load holding, note that a standard cylinder drifts on air loss—the cushions only decelerate—so add an external rod lock or pilot-operated check valve. Finally, the 850 mm stroke demands external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU63X850
- ✓ 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 SU63X850 FAQ
Yes, the SU63X850 is discontinued. The direct replacement is the AirTAC SAU63X850. It shares the same 63 mm bore, 850 mm stroke, 3/8" port, output force, and SC-series mounting accessories, fitting the exact same application.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This base SU63X850 SKU lacks a magnet and cannot take a sensor. If sensing is required, the SAU replacement supports CMSG/DMSG/EMSG switches.
