This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X250TC, 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 SU100X250TC
The AirTAC SU63-100 Standard Cylinder SU100X250TC is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X250TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X250TC
The AirTAC SU100X250TC is a discontinued double-acting profile-type cylinder with a 100mm bore and 250mm stroke. Delivering 3927N push force at 0.5MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this unit with the SAU100X250TC, a direct replacement retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series TC mounting interface.
This non-magnet SKU cannot accept a sensor. The SAU upgrade introduces CMSG/DMSG/EMSG switches for sensing variants and adds the SAUF built-in 4M valve option the SU line lacked. Note that the air cushion only decelerates the load; an external rod lock is required to hold position.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X250TC 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 SAU100X250TC 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 SU100X250TC Is Used
Heavy Stamping Press
Drives heavy stamping dies with 3927N of thrust at 0.5MPa, utilizing the compact 100mm profile body to save machine space.
Pallet Diverting
Pushes heavy pallets transversely using the TC mount, absorbing end-of-stroke impact via the 29mm adjustable air cushions.
Bulk Material Gate
Actuates large hopper gates in material handling lines, where the 1/2" port rapidly cycles the 250mm stroke under high flow.
Replacing the Airtac SU63-100 Standard Cylinder SU100X250TC with the SAU100X250TC
To replace this discontinued SU100X250TC, order the SAU100X250TC, confirming the 100mm bore, 250mm stroke, 1/2" port, PT thread, and TC mounting. Because this SKU lacks a magnet (-S), it cannot accept a sensor; if sensing is needed, the SAU replacement requires the newer CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. For load sizing, compare both directions: the 100mm bore yields 3927N push and 3681N pull at 0.5MPa, while the neighboring 80mm bore offers 2513N push. A plain cylinder drifts without live air, so use a pilot-operated check valve or rod lock for holding. The 250mm stroke is short enough to avoid rod-bending concerns, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU100X250TC
- ✓ 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 SU100X250TC FAQ
Yes, the AirTAC SU100X250TC is discontinued. The direct replacement is the SAU100X250TC. It matches the 100mm bore, 250mm stroke, 1/2" port, output force, and SC-series TC mounting, so it fits the same application directly.
At 0.5MPa it provides 3927N push and 3681N pull; at 0.7MPa it pushes 5497N, and the theoretical maximum is 801kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. If you need sensing, the SAU replacement uses CMSG/DMSG/EMSG switches.
