This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X370, 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 SU100X370
The AirTAC Airtac SU63-100 Standard Cylinder SU100X370 is a double-acting profile-type standard cylinder with a Ø100mm bore and 370mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X370, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X370
The AirTAC SU100X370 is a discontinued double-acting profile-type cylinder with a 100mm bore and 370mm stroke. Delivering 3927N push force at 0.5MPa via a 1/2" port, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this with the SAU100X370 direct replacement, preserving the exact stroke, force, port size, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade enables modern CMSG/DMSG/EMSG switches, and adds an SAUF built-in-valve option the SU line never had. Note that a plain cylinder drifts on air loss; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X370 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 SAU100X370 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 SU100X370 Is Used
Heavy Press Demolding
Provides the 3927N push at 0.5MPa needed to break heavy injection-molded parts free from deep tooling cavities.
Large Package Diversion
Actuates heavy-duty diverter arms along high-throughput packaging lines where high force and a long stroke are required.
Replacing the Airtac SU63-100 Standard Cylinder SU100X370 with the SAU100X370
To replace the SU100X370, order the SAU100X370. Verify your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware, as these are identical direct fits. Sizing checks: stepping down to an 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore provides 3927N. Since the 370mm stroke exceeds 300mm, use an external guide to prevent rod bending under side loads. This non-magnet SKU cannot take switches, but if you need sensing, the SAU replacement uses CMSG/DMSG/EMSG sensors. For loads that must not drift on air loss, add a pilot-operated check valve or rod lock, as cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU100X370
- ✓ 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 SU100X370 FAQ
Yes, the SU100X370 is discontinued. The direct replacement is the SAU100X370. It matches the 100mm bore, 370mm stroke, 3927N force, 1/2" port, and SC-series mounting. The body profile is identical, so it fits the same space.
At 0.5MPa it pushes 3927N and pulls 3681N. At 0.7MPa push is 5497N, and the theoretical max is 801kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. If you need position sensing, the SAU100X370 replacement supports CMSG/DMSG/EMSG switches.
