This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X170S, 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 SU100X170S
The AirTAC SU63-100 Standard Cylinder SU100X170S is a double-acting profile-type standard cylinder with a Ø100mm bore and 170mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X170S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X170S
The AirTAC SU100X170S is a discontinued double-acting profile-type cylinder with a 100mm bore and 170mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU100X170S, a direct upgrade retaining the exact 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.
The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X170S 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 SAU100X170S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×170 | Stroke length in mm. |
| -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 SU100X170S Is Used
Heavy Press Clamping
Secures large metal workpieces in machining centers, using the 3927 N push force at 0.5 MPa to hold parts rigidly against cutting forces.
Mold Ejection Systems
Ejects dense plastic or aluminum molds from presses, relying on the 29mm adjustable air cushions to decelerate the 25mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU100X170S with the SAU100X170S
To replace this SU100X170S, order the SAU100X170S. Confirm the 100mm bore, 170mm stroke, 1/2" port (PT/G/NPT), and SC-series mounting hardware. Because this SKU includes the -S magnet, note the sensor family changes: legacy CS1-B/DS1-B switches will not fit the SAU, requiring current CMSG/DMSG/EMSG sensors. Downgrading to an 80mm bore drops push force to 2513 N at 0.5 MPa, while staying at 100mm yields 5497 N at 0.7 MPa. A plain cylinder drifts without live air, so use an external rod lock or pilot-operated check valve for held loads. For stroke lengths over 300mm, add a guide to prevent rod bending under side loads. Consider the SAUF if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X170S
- ✓ 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 SU100X170S FAQ
Yes, the AirTAC SU100X170S is discontinued. The direct replacement is the SAU100X170S. It shares the same 100mm bore, 170mm stroke, 1/2" port, output force, and SC-series mounting, so it fits the same application without modification.
The cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
