This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X375S, 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 SU63X375S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X375S is a double-acting profile-type standard cylinder with a Ø63mm bore and 375mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X375S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X375S
The AirTAC SU63X375S is a discontinued double-acting profile-type cylinder with a 63mm bore and 375mm stroke. It features an extruded aluminum barrel and adjustable air cushions at both ends, delivering 1559 N push and 1402 N pull at 0.5 MPa via its 3/8" port. AirTAC replaced this legacy unit with the SAU63X375S, a direct replacement retaining the exact bore, stroke, output force, and SC-series mounting.
When upgrading, note that the SAU replacement transitions to current CMSG/DMSG/EMSG sensors, retiring the older CS1-B/DS1-B switches used on this -S magnet 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 SAU63X375S 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 SAU63X375S 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 SU63X375S Is Used
Package Diverting
Drives diverter arms on packaging lines, utilizing the 1559 N push force to redirect heavy cartons at high speeds.
Pallet Stopping
Acts as a robust end-stop for accumulated pallets on roller conveyors, absorbing kinetic energy via adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X375S with the SAU63X375S
To replace this discontinued SU63X375S, order the SAU63X375S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes a magnet (-S), you must switch your legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If you need integrated flow control, explore the SAUF variant with its built-in valve. For the 375mm stroke, use an external guide to prevent rod bending and side-load damage. If comparing alternatives, a 50mm bore yields 982 N push at 0.5 MPa, while an 80mm bore provides 2513 N. Remember, a standard cylinder drifts without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X375S
- ✓ 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 SU63X375S FAQ
Yes, the SU63X375S is discontinued. The direct replacement is the AirTAC SAU63X375S. It matches the 63mm bore, 375mm stroke, 1559 N force, 3/8" port, and SC-series mounting, but requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
This double-acting cylinder uses a 3/8" port. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. Note that the air cushions only decelerate the load; they do not hold it without live air.
