This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X500SFA, 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 SU100X500SFA
The AirTAC Airtac SU63-100 Standard Cylinder SU100X500SFA is a double-acting profile-type standard cylinder with a Ø100mm bore and 500mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X500SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X500SFA
The AirTAC SU100X500SFA is a discontinued double-acting profile cylinder with a 100 mm bore, 500 mm stroke, and an FA mount. Delivering 3927 N of push force at 0.5 MPa, it is replaced by the SAU100X500SFA. This direct successor shares the exact bore, stroke, 1/2" port, and SC-series mounting interface.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this SU -S model, and adds a new SAUF built-in-valve option. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X500SFA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X500SFA 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 SU100X500SFA Is Used
Heavy Press Ejection
Provides the 3927 N push force needed to eject dense stamped parts from a hydraulic press bed over a 500 mm travel distance.
Pallet Discharge
Handles the physical mass of loaded pallets on a conveyor line, utilizing the 200 kg vertical lift capacity with a safe margin.
Mold Handling
Moves heavy injection molds into staging position, taking advantage of the FA mounting bracket and 100 mm bore stability.
Replacing the Airtac SU63-100 Standard Cylinder SU100X500SFA with the SAU100X500SFA
To replace the SU100X500SFA, order the SAU100X500SFA, confirming the 100 mm bore, 500 mm stroke, 1/2" port, M20x1.5 rod thread, and FA mounting. If sizing alternatives, a 100 mm bore yields 3927 N push and 3681 N pull at 0.5 MPa (5497 N at 0.7 MPa), while an 80 mm bore provides 2513 N push. The -S magnet requires migrating from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For the 500 mm stroke, use external guides to prevent rod bending under side loads. The cylinder will drift without air; install a pilot-operated check valve for load holding. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU100X500SFA
- ✓ 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 SU100X500SFA FAQ
Yes, the SU100X500SFA is discontinued. The direct replacement is the SAU100X500SFA, which matches the 100 mm bore, 500 mm stroke, 1/2" port, output force, and SC-series FA mounting. You simply order the SAU equivalent.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a max of 801 kgf at 1.0 MPa. Because your SU has an -S magnet for CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement.
