This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X475S, 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 SU63X475S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X475S is a double-acting profile-type standard cylinder with a Ø63mm bore and 475mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X475S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X475S
The AirTAC SU63X475S is a discontinued double-acting profile-type cylinder with a 63mm bore and 475mm stroke. Delivering 1559N push and 1402N pull at 0.5MPa, it features a 3/8" port and an extruded aluminum body that is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU63X475S, matching the bore, stroke, force, port, and SC-series mounting.
When upgrading to the SAU63X475S, the body and mechanics remain identical, but the piston magnet now interfaces with current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors on this SU model. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X475S 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 SAU63X475S 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 SU63X475S Is Used
Pallet Diversion
Uses the 1559N push force at 0.5MPa to deflect heavy pallets along a high-speed sorting line, absorbing end-of-stroke impact via the 21mm adjustable cushions.
Long-Reach Part Transfer
Moves components across a 475mm gap; external linear guides are required to support the rod and prevent binding or bending under offset loads.
Replacing the Airtac SU63-100 Standard Cylinder SU63X475S with the SAU63X475S
To replace this discontinued SU63X475S, order the SAU63X475S direct equivalent, verifying the 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Because this unit has a -S magnet, note that your legacy CS1-B/DS1-B switches must be swapped for CMSG/DMSG/EMSG sensors on the SAU. If you need integrated air control, explore the SAUF valve-cylinder variant. For load sizing, a 50mm bore offers 982N push @0.5MPa, while an 80mm bore yields 2513N. Remember, a standard cylinder drifts without live air; the cushions only decelerate near stroke end, so use an external rod lock or pilot-operated check valve for load holding. Finally, at 475mm stroke, prevent rod bending by guiding the load externally to avoid side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU63X475S
- ✓ 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 SU63X475S FAQ
Yes, the SU63X475S is discontinued. The direct replacement is the SAU63X475S, which shares the identical 63mm bore, 475mm stroke, 3/8" port, output force, and SC-series mounting.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches are incompatible with the SAU replacement, which requires current CMSG/DMSG/EMSG sensors.
