This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X315S, 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 SU100X315S
The AirTAC SU63-100 Standard Cylinder SU100X315S is a double-acting profile-type standard cylinder with a Ø100mm bore and 315mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X315S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X315S
The AirTAC SU100X315S is a discontinued double-acting profile-type cylinder with a 100mm bore and 315mm stroke. It delivers 3927N push force at 0.5MPa and features a 1/2" port. AirTAC replaced it with the SAU100X315S direct replacement, retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of this unit's legacy CS1-B/DS1-B switches, and adds a SAUF valve-integrated option. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

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 SAU100X315S 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 SU100X315S Is Used
Heavy Press Clamping
Secures large steel plates in a machining fixture, utilizing the 3927N push force at 0.5MPa for rigid holding.
Pallet Reject Arm
Pushes overweight pallets off a high-capacity conveyor line using the 200kg safe vertical lift capacity.
Automated Assembly Ram
Drives heavy industrial components downward into housings, relying on the 315mm stroke and adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU100X315S with the SAU100X315S
To replace this SU100X315S with the SAU100X315S, verify the 100mm bore, 315mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. A plain cylinder drifts without live air; the 29mm cushions only decelerate, so use an external rod lock for load holding. At 315mm stroke, prevent rod bending by adding external guides to handle side loads. If you need less force, step down to the 80mm bore (2513N push at 0.5MPa); if you need more, 0.7MPa yields 5497N here. The SAUF variant offers a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU100X315S
- ✓ 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 SU100X315S FAQ
Yes, the SU100X315S is discontinued. The direct replacement is the AirTAC SAU100X315S. It shares the identical 100mm bore, 315mm stroke, 1/2" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 3927N push and 3681N pull, 5497N push at 0.7MPa, and a theoretical max of 801kgf at 1.0MPa. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades these to CMSG/DMSG/EMSG sensors.
