This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X75S, 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 SU63X75S
The AirTAC SU63-100 Standard Cylinder SU63X75S is a double-acting profile-type standard cylinder with a Ø63mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X75S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X75S
The AirTAC SU63X75S is a discontinued double-acting profile-type cylinder with a 63mm bore and 75mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X75S, a direct upgrade retaining the exact body, stroke, force, and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than equivalent ISO cylinders. Note the -S magnet used legacy CS1-B/DS1-B switches, whereas the SAU successor requires CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF valve-integrated variant this SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X75S 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 SAU63X75S 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 SU63X75S Is Used
Mid-Tonnage Clamping
Secures heavy steel workpieces during CNC machining, utilizing the 1559N push force at 0.5MPa for rigid, zero-shift holding.
Package Diverting
Drives robust routing gates on high-throughput packaging lines, where the 75mm stroke provides rapid and precise parcel redirection.
Pallet Stops
Acts as a heavy-duty end-stop for accumulated pallets on roller conveyors, safely absorbing kinetic energy via adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X75S with the SAU63X75S
To replace this SU63X75S, order the SAU63X75S. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are unchanged. Because the -S magnet is present, expect a sensor family change: legacy CS1-B/DS1-B switches will not fit the SAU groove, requiring current CMSG/DMSG/EMSG sensors. For force context, this 63mm bore yields 1559N push at 0.5MPa; if undersized, the 80mm bore offers 2513N. Remember, the 21mm adjustable air cushions only decelerate the piston near stroke ends—they do not hold loads. For drop prevention on air loss, install an external rod lock or pilot-operated check valve. The SAUF built-in 4M solenoid valve variant is worth exploring if you want to simplify piping.
Replacement checklist
- ✓ Same bore / stroke → SAU63X75S
- ✓ 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 SU63X75S FAQ
Yes, the SU63X75S is discontinued. The direct replacement is the AirTAC SAU63X75S. It shares the identical 63mm bore, 75mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it drops right into the same application.
At 0.5MPa it pushes 1559N and pulls 1402N; at 0.7MPa it pushes 2182N, with a theoretical max of 318kgf at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to current CMSG/DMSG/EMSG sensors.
