This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X50, 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 SU100X50
The AirTAC Airtac SU63-100 Standard Cylinder SU100X50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 50mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X50, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X50
The AirTAC SU100X50 is a discontinued double-acting profile-type cylinder with a 100mm bore and 50mm stroke. It delivers a robust 3927 N push force at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU100X50, a direct upgrade retaining the exact bore, stroke, output force, 1/2" port and SC-series mounting footprint.
Because this specific SKU lacks a magnet, it cannot accept a position switch. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in-valve variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X50 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 SAU100X50 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 SU100X50 Is Used
Heavy Press Operations
Applies the 3927 N push at 0.5 MPa for clamping and stamping dense materials in automated fabrication lines.
Mold Ejection Systems
Provides the high breakout force needed to eject heavy molded products from stationary tooling.
Replacing the Airtac SU63-100 Standard Cylinder SU100X50 with the SAU100X50
To replace this SU100X50, order the SAU100X50 and confirm the 100mm bore, 50mm stroke, 1/2" port, M20x1.5 rod thread and SC-series mounting. This no-magnet SKU cannot take a sensor; if you need detection, the SAU upgrade requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. If downsizing, a 80mm bore yields 2513 N push at 0.5 MPa; if upsizing is required, you are at the maximum standard bore. The SAUF valve-integrated option can simplify cycle plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU100X50
- ✓ 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 SU100X50 FAQ
Yes, the SU100X50 is discontinued. The direct replacement is the AirTAC SAU100X50. It matches the 100mm bore, 50mm stroke, force, 1/2" port and SC-series mounting, so it fits the same application without mechanical changes.
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. Because this SKU has no magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
