This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X250CA, 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 SU100X250CA
The AirTAC SU63-100 Standard Cylinder SU100X250CA 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 SAU100X250CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X250CA
The AirTAC SU100X250CA is a discontinued double-acting profile-type cylinder with a 100mm bore and 250mm stroke. It delivers a push force of 3927 N at 0.5 MPa (3681 N pull) through a 1/2" port. The direct replacement is the SAU100X250CA, matching the bore, stroke, output, port and SC-series CA mounting.
This extruded aluminium body is more compact than an ISO 15552 equivalent. Because this SKU lacks a magnet, it cannot take a sensor. The SAU upgrade also adds the SAUF built-in-valve variant the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X250CA 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 SAU100X250CA 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 SU100X250CA Is Used
Heavy Stamp Pressing
Ideal for driving heavy stamping dies, utilizing the 3927 N push force at 0.5 MPa to form thick metal components reliably.
Large Clamp Fixtures
Secures large industrial parts during machining, using the CA mount to handle high side-load stresses on the factory floor.
Replacing the Airtac SU63-100 Standard Cylinder SU100X250CA with the SAU100X250CA
To replace this SU100X250CA, order the SAU100X250CA and confirm the 100mm bore, 250mm stroke, 1/2" port, M20x1.5 rod thread and CA mounting. Sizing both ways: stepping down to an 80mm bore yields 2513 N push at 0.5 MPa, while a 100mm bore at 0.7 MPa provides 5497 N. Note that this no-magnet SKU cannot accept a sensor, whereas the SAU replacement supports CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). The 250mm stroke is under the 300mm side-load threshold, but always guide the load to prevent rod bending. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. If self-switching is needed, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU100X250CA
- ✓ 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 SU100X250CA FAQ
Yes, the AirTAC SU100X250CA is discontinued. The direct replacement is the SAU100X250CA. It provides the same 100mm bore, 250mm stroke, output force, 1/2" port, and SC-series CA mounting compatibility.
The 100mm bore provides 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. This specific SKU has no magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
