This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X500S, 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 SU100X500S
The AirTAC SU63-100 Standard Cylinder SU100X500S 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 SAU100X500S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X500S
The AirTAC SU100X500S is a discontinued double-acting profile-type cylinder with a 100mm bore and 500mm stroke. AirTAC replaced this legacy unit with the SAU100X500S. The SAU is a direct upgrade: identical 100mm bore, 500mm stroke, 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches. The SAU replacement transitions to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. A plain cylinder does not hold load without live air; the adjustable 29 mm cushions only decelerate near stroke end.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X500S 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 SAU100X500S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU100X500S Is Used
Press Ejection
Ejects heavy stamped parts from a press bed using 3927 N of push force over the 500mm stroke.
Automated Storage
Actuates heavy shelving pushers in automated retrieval systems, guided externally to prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU100X500S with the SAU100X500S
To replace the discontinued SU100X500S, order the SAU100X500S. Confirm your 1/2" port thread (PT, G, or NPT) and SC-series mounting (LB, FA, FB, CA, CB, TC). Since this is an -S model, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. The 100mm bore provides 3927 N push at 0.5 MPa; if you need less force, a 80mm bore yields 2513 N push. For higher force, 100mm is the largest profile size available, so exceeding 801 kgf at 1.0 MPa requires multiple cylinders. With a 500mm stroke, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. Consider the SAUF for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU100X500S
- ✓ 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 SU100X500S FAQ
Yes, the SU100X500S is discontinued. The direct replacement is the AirTAC SAU100X500S. It shares the same 100mm bore, 500mm stroke, 1/2" port, output force, and SC-series mounting. The only change for -S buyers is that the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU.
The 1/2" port is fixed by the 100mm bore. It provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The piston rod is 25mm with an M20x1.5 thread, and speed ranges from 30-800 mm/s.
