This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X502S, 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 SU63X502S
The AirTAC SU63-100 Standard Cylinder SU63X502S is a double-acting profile-type standard cylinder with a Ø63mm bore and 502mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X502S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X502S
The AirTAC SU63X502S is a discontinued double-acting profile cylinder with a 63mm bore and 502mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, making it a robust mid-range actuator. The direct replacement is the SAU63X502S, matching the bore, stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because it is an extruded aluminum profile barrel, it is shorter and more compact than an ISO 15552 cylinder of the same size.
The -S magnet on this legacy model works with CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF variant with a built-in 4M solenoid valve the SU lacked. A plain cylinder drifts on air loss; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X502S 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 SAU63X502S 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 SU63X502S Is Used
Carton Diverting
Pushes heavy packages on a sorting line with a safe 935N working load, utilizing the 502mm stroke to clear the belt lane.
Pallet Positioning
Indexes loaded pallets laterally at 0.5MPa, providing robust 1559N push force while reusing existing SC-series mounts.
Material Pressing
Holds workpieces under a steady 1402N pull force, requiring an external rod lock to maintain position if air pressure drops.
Replacing the Airtac SU63-100 Standard Cylinder SU63X502S with the SAU63X502S
To replace the SU63X502S, order the SAU63X502S direct equivalent. Verify your 3/8" port thread (PT, G, or NPT) and SC-series mounting (LB, FA, FB, CA, CB, TC). Because this SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If you need integrated flow control, explore the SAUF variant with its built-in valve. At 0.5MPa the 63mm bore yields 1559N push; if you need less force, step down to a 50mm bore (982N push), or step up to an 80mm bore (2513N push) for heavier loads. With a 502mm stroke, use external guides to prevent rod bending and side-load damage. Remember that the air cushion only decelerates the piston; it does not hold the load, so add a pilot-operated check valve for vertical applications.
Replacement checklist
- ✓ Same bore / stroke → SAU63X502S
- ✓ 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 SU63X502S FAQ
Yes, the SU63X502S is discontinued. The direct replacement is the SAU63X502S, which shares the identical 63mm bore, 502mm stroke, 3/8" port, output force, and SC-series mounting accessories.
At 0.5MPa it provides 1559N push and 1402N pull, reaching 2182N push at 0.7MPa, 2805N at 0.9MPa, and a 318kgf maximum at 1.0MPa. The -S magnet on this legacy model used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
