This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X50STC, 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 SU100X50STC
The AirTAC Airtac SU63-100 Standard Cylinder SU100X50STC 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 SAU100X50STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X50STC
The AirTAC SU100X50STC is a discontinued double-acting profile-type cylinder with a 100mm bore and 50mm stroke, delivering 3927 N push and 3681 N pull at 0.5 MPa. It features an extruded aluminum barrel and adjustable air cushions at both ends, making it shorter and more compact than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU100X50STC, which matches the original 1/2" port, M20x1.5 rod thread, force output, and SC-series TC mounting.
When upgrading to the SAU100X50STC, the body, bore, stroke, and TC mount remain identical. A key change is that this legacy SU model's -S magnet used CS1-B/DS1-B switches, whereas the SAU replacement utilizes the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

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 SAU100X50STC 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 SU100X50STC Is Used
Heavy Pallet Clamping
Secures large loaded pallets during transfer, utilizing the 100mm bore's 200 kg vertical lift capacity to maintain firm grip under varying shop air pressures.
Press Die Actuation
Drives short-stroke pressing and stamping dies where the 3927 N output at 0.5 MPa provides consistent force for light assembly and component seating tasks.
Injection Mold Ejection
Ejects heavy molded parts from stationary platens, relying on the 29 mm adjustable air cushions to decelerate the 25 mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU100X50STC with the SAU100X50STC
To replace the discontinued SU100X50STC, order the SAU100X50STC, confirming the 100mm bore, 50mm stroke, 1/2" port (PT/G/NPT), and TC mounting accessory are retained for a direct fit. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the SAU model. If you need to downsize, the 80mm bore yields 2513 N push at 0.5 MPa; if you need more force, this 100mm bore is the largest standard profile option. For applications requiring held loads, remember this cylinder does not lock on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve. You may also consider the SAUF variant if you want a built-in valve to eliminate external plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU100X50STC
- ✓ 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 SU100X50STC FAQ
Yes, the AirTAC SU100X50STC is discontinued and end-of-life. The direct replacement is the SAU100X50STC. It offers the same 100mm bore, 50mm stroke, 1/2" port, output force, and TC mounting interface, so it fits the same application directly.
At 0.5 MPa it provides 3927 N push and 3681 N pull, increasing to 5497 N push 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 SAU100X50STC replacement requires the current CMSG/DMSG/EMSG sensor family.
