This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X140, 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 SU100X140
The AirTAC Airtac SU63-100 Standard Cylinder SU100X140 is a double-acting profile-type standard cylinder with a Ø100mm bore and 140mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X140, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X140
The AirTAC SU100X140 is a discontinued double-acting profile-type cylinder with a 100mm bore and 140mm stroke. Delivering 3927 N push and 3681 N pull at 0.5 MPa, its direct replacement is the SAU100X140, sharing the same extruded aluminium body, 1/2" port, M20x1.5 rod thread and SC-series mounts.
This compact profile body is shorter than a same-bore ISO 15552 unit. Note this non-magnetic SKU cannot take a sensor, and the SAU upgrade switches to CMSG/DMSG/EMSG switches while adding a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X140 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 SAU100X140 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 SU100X140 Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures using 3927 N of thrust at 0.5 MPa for rigid, high-force holding.
Stamping Ejection
Ejects heavy formed parts from hydraulic presses, utilising the 25mm rod and adjustable 29mm cushions to absorb impact.
Replacing the Airtac SU63-100 Standard Cylinder SU100X140 with the SAU100X140
To replace this SU100X140, order the SAU100X140 with the identical 100mm bore, 140mm stroke, 1/2" port and SC-series mounting hardware. Because this is a non-magnetic SKU, it cannot accept a sensor; if you need position detection on the SAU, specify the -S option and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing down, a 80mm bore yields 2513 N push at 0.5 MPa; sizing up is not available beyond 100mm. A plain cylinder drifts on air loss—the 29mm cushions only decelerate—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF variant integrates a 4M valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU100X140
- ✓ 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 SU100X140 FAQ
Yes, the AirTAC SU100X140 is discontinued. The direct replacement is the SAU100X140. It matches the 100mm bore, 140mm stroke, 1/2" port, output force, and SC-series mounting accessories, fitting the exact same application.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches if you order the -S version.
