This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X35S, 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 SU63X35S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X35S is a double-acting profile-type standard cylinder with a Ø63mm bore and 35mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X35S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X35S
The AirTAC SU63X35S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 35 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same size and delivers 1559 N push at 0.5 MPa. AirTAC replaced this end-of-line model with the SAU63X35S, a direct upgrade retaining the exact 3/8" port, M16x1.5 rod thread, output force, and SC-series mounting.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches, whereas the SAU replacement now takes current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X35S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X35S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×35 | 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 SU63X35S Is Used
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure medium-weight workpieces during machining operations.
Package Diverting
Uses the short 35 mm stroke to rapidly push cartons off a main conveyor belt into secondary packing lanes.
Pallet Stops
Acts as a high-force pneumatic stop pin to halt pallets precisely at a workstation on a roller conveyor.
Replacing the Airtac SU63-100 Standard Cylinder SU63X35S with the SAU63X35S
To replace this SU63X35S, order the SAU63X35S and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. If the 35 mm stroke is too short, the neighboring 50 mm bore provides 982 N push at 0.5 MPa, while the 80 mm bore offers 2513 N. Remember that a plain double-acting cylinder drifts without live air; the adjustable 21 mm cushions only decelerate the piston near the end of travel, so install an external rod lock or pilot-operated check valve for secure load holding. Finally, note the sensor family change: your existing CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG models on the new SAU.
Replacement checklist
- ✓ Same bore / stroke → SAU63X35S
- ✓ 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 SU63X35S FAQ
Yes, the SU63X35S is discontinued. The direct replacement is the AirTAC SAU63X35S. It shares the identical 63 mm bore, 35 mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application without mechanical modifications.
At 0.5 MPa it provides 1559 N push and 1402 N pull, increasing to 2182 N push at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. Because this is an -S magnet model, it originally used legacy CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
