This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X25TC, 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 SU100X25TC
The AirTAC SU63-100 Standard Cylinder SU100X25TC is a double-acting profile-type standard cylinder with a Ø100mm bore and 25mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X25TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X25TC
The AirTAC SU100X25TC is a discontinued double-acting profile-type cylinder with a 100mm bore and 25mm stroke. It delivers 3927 N of push force at 0.5 MPa through a 1/2" port. AirTAC replaced this end-of-line unit with the SAU100X25TC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting accessory.
Because this specific SKU lacks a magnet, it cannot accept a piston switch. If sensing is needed on the new SAU unit, you must use the current CMSG/DMSG/EMSG sensor family rather than the legacy CS1-B/DS1-B switches. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X25TC 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 SAU100X25TC 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 SU100X25TC Is Used
Heavy-Duty Stamping
Applies the 3927 N push force at 0.5 MPa for short-stroke metal forming, crimping, and riveting operations in automated fabrication lines.
High-Load Diverting
Handles robust package diverting or heavy pallet halting using the TC mount and compact profile body, fitting tight machinery spaces.
Replacing the Airtac SU63-100 Standard Cylinder SU100X25TC with the SAU100X25TC
To replace the discontinued SU100X25TC, order the SAU100X25TC, confirming the 100mm bore, 25mm stroke, 1/2" port, M20x1.5 rod thread, and TC mounting interface. If you need to size both ways, stepping down to an 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore provides 3927 N. Note that a plain cylinder drifts without live air—the 29mm adjustable cushion only decelerates the piston near stroke end, so install an external rod lock or pilot-operated check valve for secure load holding. Although the 25mm stroke is very short, always ensure adequate guidance to prevent rod-bending side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X25TC
- ✓ 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 SU100X25TC FAQ
Yes, the SU100X25TC is discontinued. The direct replacement is the SAU100X25TC, which matches the 100mm bore, 25mm stroke, 1/2" port, and TC mounting. The body, force, and SC-series accessory compatibility remain unchanged.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor; if ordering the SAU replacement with a magnet (-S), you must use CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
