This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X370SFA, 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 SU80X370SFA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X370SFA is a double-acting profile-type standard cylinder with a Ø80mm bore and 370mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X370SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X370SFA
The AirTAC SU80X370SFA is a discontinued double-acting profile-type cylinder with an 80mm bore, 370mm stroke, and an FA mounting interface. Delivering 2513 N push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU80X370SFA, a direct upgrade retaining the exact bore, stroke, 3/8" port, and SC-series mounting.
The SAU replacement modernizes the sensor system: this legacy SU used CS1-B/DS1-B switches, while the SAU takes current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU never offered. Note that a standard cylinder drifts without live air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X370SFA 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 SAU80X370SFA 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 SU80X370SFA Is Used
Pallet Diverting
Uses the 2513 N push force at 0.5 MPa to deflect heavy pallets along a sorting line, relying on the FA mount for rigid body fixing.
Vertical Lift Gate
Raises a 128 kg material gate using the 370mm stroke, requiring an external check valve to prevent drifting when air pressure is lost.
Press Ejection
Ejects formed metal parts from a press bed, where the 28mm adjustable cushions decelerate the 80mm piston smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X370SFA with the SAU80X370SFA
To replace this SU80X370SFA, order the SAU80X370SFA, matching the 80mm bore, 370mm stroke, 3/8" port, M20x1.5 rod thread, and FA mount. If your machine used the -S magnet, you must upgrade your switches from the old CS1-B/DS1-B to the modern CMSG/DMSG/EMSG family. When sizing, a neighboring 63mm bore provides 1559 N push at 0.5 MPa, while a 100mm bore offers 3927 N. The 370mm stroke demands attention: prevent rod bending by guiding the load externally to avoid side-load forces. Remember that the adjustable 28mm air cushions only decelerate the piston near stroke end and do not hold the load on air loss—install a pilot-operated check valve or rod lock if drop prevention is required.
Replacement checklist
- ✓ Same bore / stroke → SAU80X370SFA
- ✓ 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 SU80X370SFA FAQ
Yes, the AirTAC SU80X370SFA is discontinued. The direct replacement is the SAU80X370SFA. It shares the identical 80mm bore, 370mm stroke, 3/8" port, output force, and SC-series FA mounting, so it drops right into the same application.
At 0.5 MPa it provides 2513 N push and 2268 N pull, increasing to 3518 N push at 0.7 MPa, with a theoretical max of 513 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
