This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X175, 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 SU100X175
The AirTAC Airtac SU63-100 Standard Cylinder SU100X175 is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X175, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X175
The AirTAC SU100X175 is a discontinued double-acting profile-type cylinder featuring a 100mm bore and 175mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same size while sharing AirTAC SC-series mounting accessories. It delivers a robust 3927 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU100X175, a direct replacement retaining the exact 1/2" port, M20x1.5 rod thread, and 29mm adjustable cushions.
The SAU100X175 matches the original body, bore, stroke, and output force perfectly. Because this specific SU SKU lacks a magnet (-S), it cannot accept a sensor. If sensing is needed on the SAU upgrade, note that the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family. 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 SAU100X175 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 SAU100X175 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 SU100X175 Is Used
Heavy Press Clamping
Ideal for securing heavy metal components during machining, utilizing the 3927 N push force at 0.5 MPa to hold large workpieces firmly in place.
Stamping Ejectors
Ejects heavy stamped parts from press dies, benefiting from the 29mm adjustable air cushions at both ends to decelerate the 25mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU100X175 with the SAU100X175
To replace the discontinued SU100X175, order the SAU100X175. Confirm your 1/2" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Since this SKU has no magnet, it cannot support a magnetic switch; if you require position sensing on the new SAU, you must add the -S option and migrate to CMSG/DMSG/EMSG sensors. Sizing both ways: a neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 100mm bore provides 3927 N. At 175mm stroke, side-load risks are low, but always guide the load to prevent rod bending. Note that a plain cylinder drifts on air loss—the cushions only decelerate near stroke ends—so use an external rod lock or pilot-operated check valve for secure load holding. For faster cycling, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU100X175
- ✓ 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 SU100X175 FAQ
Yes, the AirTAC SU100X175 is discontinued and end-of-life. The direct replacement is the SAU100X175. It provides identical performance with the same 100mm bore, 175mm stroke, 1/2" port, and SC-series mounting compatibility. You can order the SAU100X175 as a direct physical swap.
This double-acting cylinder delivers a push of 3927 N and pull of 3681 N at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches if you add the -S option.
