This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X250SN, 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 SU100X250SN
The AirTAC SU63-100 Standard Cylinder SU100X250SN 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 SAU100X250SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X250SN
The AirTAC SU100X250SN is a discontinued double-acting profile-type cylinder with a 100mm bore and 250mm stroke. It delivers 3927 N push and 3681 N pull force at 0.5 MPa. The direct replacement is the SAU100X250SN, matching the 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting accessories.
This extruded aluminium body is shorter than an ISO 15552 cylinder of the same bore. The -N NBR seal handles -20 to +70 C, while the -S magnet works with legacy CS1-B/DS1-B switches; the SAU upgrade switches to CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X250SN 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 SAU100X250SN 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 SU100X250SN Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures, utilizing the 3927 N push force at 0.5 MPa to hold components rigidly against cutting forces.
Mould Ejection Systems
Drives the ejection of dense composite moulds from hydraulic presses, benefiting from the 29 mm adjustable end cushions to safely stop the 250mm stroke.
Replacing the Airtac SU63-100 Standard Cylinder SU100X250SN with the SAU100X250SN
To replace this SU100X250SN, order the SAU100X250SN direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounts (LB/FA/FB/CA/CB). Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to the CMSG/DMSG/EMSG family on the new cylinder. If sizing alternatives, a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, whereas the 100mm bore hits 5497 N at 0.7 MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. For the 250mm stroke, ensure guide rails to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X250SN
- ✓ 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 SU100X250SN FAQ
Yes, the SU100X250SN is discontinued. The direct replacement is the SAU100X250SN. It matches the 100mm bore, 250mm stroke, 1/2" port, output force, and SC-series mounting. The SAU body also offers the new SAUF built-in 4M solenoid valve option the SU line lacked.
The bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and an 801 kgf maximum at 1.0 MPa. Because this SKU includes the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU100X250SN replacement requires the current CMSG/DMSG/EMSG sensor family.
