This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X540S, 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 SU63X540S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X540S is a double-acting profile-type standard cylinder with a Ø63mm bore and 540mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X540S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X540S
The AirTAC SU63X540S is a discontinued double-acting profile-type cylinder with a 63mm bore and 540mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, utilizing a 3/8" port and a 20mm piston rod. AirTAC replaced this end-of-line unit with the SAU63X540S, a direct alternative retaining the exact bore, stroke, force, port, and SC-series mounting footprint.
Two upgrades define the SAU successor: the legacy CS1-B/DS1-B switches used on this -S magnet model are replaced by current CMSG/DMSG/EMSG sensors, and the new SAUF variant offers a built-in 4M solenoid valve the SU line lacked. Note that standard cylinders drift without live air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X540S 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 SAU63X540S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU63X540S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using the 1559N thrust at 0.5MPa, with the 540mm stroke clearing wide transfer lanes.
Vertical Lift Gate
Raises a horizontal access gate via the 79kg vertical lift capacity, though an external check valve is required to prevent the gate from drifting downward.
Long-Reach Pressing
Extends 540mm to reach into deep machine frames for light component seating, relying on external guides to prevent rod deflection.
Replacing the Airtac SU63-100 Standard Cylinder SU63X540S with the SAU63X540S
To replace this SU63X540S, order the SAU63X540S, verifying the 3/8" port, M16x1.5 rod thread, and SC-series mounting accessories (LB/FA/FB/CA/CB). Because the -S magnet is present, you must migrate from the obsolete CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. For force sizing, this 63mm bore outputs 1559N push at 0.5MPa; if you need less force, a 50mm bore provides 982N, while an 80mm bore offers 2513N. At 540mm, this long stroke demands external guide rails to prevent rod bending under side loads. Finally, the air cushions only decelerate the piston near stroke end; they do not hold loads on air loss, so add a pilot-operated check valve if drift is unacceptable.
Replacement checklist
- ✓ Same bore / stroke → SAU63X540S
- ✓ 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 SU63X540S FAQ
Yes, the SU63X540S is discontinued. The direct replacement is the AirTAC SAU63X540S. It matches the 63mm bore, 540mm stroke, 3/8" port, output force, and SC-series mounting accessories. The only change for buyers is that the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 63mm bore features a 3/8" air port and a 20mm rod. It generates 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical maximum of 318kgf at 1.0MPa.
