This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X350S, 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 SU100X350S
The AirTAC SU63-100 Standard Cylinder SU100X350S is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X350S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X350S
The AirTAC SU100X350S is a discontinued double-acting profile-type cylinder with a 100mm bore and 350mm stroke. Delivering 3927 N push force at 0.5 MPa, its direct replacement is the SAU100X350S, matching the bore, stroke, output, 1/2" port and SC-series mounting.
The SAU upgrade retains the compact extruded aluminum body but switches the -S magnet compatibility from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. It also introduces the SAUF built-in 4M valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X350S 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 SAU100X350S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU100X350S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×350 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU100X350S Is Used
Heavy Press Ejection
Provides the 3927 N push at 0.5 MPa needed to eject dense stamped metal parts from a hydraulic press bed.
Pallet Stopper Gate
Acts as a robust 100mm bore barrier to halt loaded pallets on a conveyor, safely absorbing kinetic energy.
Mold Clamping Arm
Secures heavy injection molds during tool changes, utilizing the 350mm stroke to clear the machine envelope.
Replacing the Airtac SU63-100 Standard Cylinder SU100X350S with the SAU100X350S
To replace the SU100X350S, order the SAU100X350S and verify the 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this -S model used legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors. If sizing down, the 80mm bore yields 2513 N push at 0.5 MPa; if sizing up, higher pressure reaches 5497 N at 0.7 MPa. For the 350mm stroke, use an external guide to prevent rod bending under side loads. The cushion only decelerates; use a pilot-operated check valve for load holding. The SAUF valve-integrated option can simplify actuation.
Replacement checklist
- ✓ Same bore / stroke → SAU100X350S
- ✓ 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 SU100X350S FAQ
Yes, the SU100X350S is discontinued. The direct replacement is the SAU100X350S, which shares the same 100mm bore, 350mm stroke, force, 1/2" port, and SC-series mounting accessories.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches are retired; the SAU replacement uses CMSG/DMSG/EMSG sensors.
