This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X125TC, 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 SU100X125TC
The AirTAC SU63-100 Standard Cylinder SU100X125TC is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X125TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X125TC
The AirTAC SU100X125TC is a discontinued double-acting profile-type standard cylinder with a 100 mm bore and 125 mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, utilizing a 25 mm piston rod and a 1/2" air port. AirTAC replaced this end-of-line unit with the SAU100X125TC, a direct upgrade retaining the exact same body dimensions, force output, and SC-series TC mounting interface.
Because this specific SKU lacks a magnet, it cannot accept position sensors. If sensing is required on the replacement, the SAU -S variant uses modern CMSG, DMSG, or EMSG switches instead of the legacy CS1-B/DS1-B family. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X125TC 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 SAU100X125TC 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 SU100X125TC Is Used
Heavy Stamp Press Feed
Pushes metal blanks into a hydraulic press with 3927 N at 0.5 MPa, utilizing the 125 mm stroke for rapid, short-cycle insertion.
Pallet Load Rejector
Diverts heavy pallets up to 200 kg off a main conveyor line using the TC mount to absorb high lateral rejection forces.
Mold Clamp Actuation
Secures injection mold halves with a theoretical maximum of 801 kgf at 1.0 MPa, relying on the 25 mm rod for rigid alignment.
Replacing the Airtac SU63-100 Standard Cylinder SU100X125TC with the SAU100X125TC
To replace the SU100X125TC, order the SAU100X125TC and verify your 1/2" port threads (PT, G, or NPT) alongside the M20x1.5 rod-end connection. The TC mounting accessory from the AirTAC SC series carries over directly. Since this original unit has no magnet (-S), it cannot support sensors; if your application now requires end-of-stroke detection, specify an SAU100X125TC-S and upgrade to CMSG/DMSG/EMSG reed switches. When sizing, note that dropping to an 80 mm bore reduces push force to 2513 N at 0.5 MPa, whereas this 100 mm bore provides 3927 N. Remember that a standard cylinder drifts without live air—the adjustable 29 mm cushions only decelerate the piston near stroke end, so integrate an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X125TC
- ✓ 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 SU100X125TC FAQ
Yes, the SU100X125TC is discontinued. The direct replacement is the AirTAC SAU100X125TC. It matches the 100 mm bore, 125 mm stroke, 3927 N force at 0.5 MPa, 1/2" port, and SC-series TC mounting. You just swap the cylinder without altering the machine footprint.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. Because this specific SKU lacks an -S magnet, it cannot accept magnetic switches; the SAU -S replacement uses CMSG, DMSG, or EMSG sensors instead of the old CS1-B/DS1-B types.
