This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X780S, 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 SU63X780S
The AirTAC SU63-100 Standard Cylinder SU63X780S is a double-acting profile-type standard cylinder with a Ø63mm bore and 780mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X780S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X780S
The AirTAC SU63X780S is a discontinued double-acting profile-type cylinder with a 63mm bore and 780mm stroke. The direct replacement is the SAU63X780S, retaining the same 3/8" port, M16x1.5 rod thread, 20mm rod, and SC-series mounting compatibility.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line lacked. Both the old and new models feature an extruded aluminum body that is shorter and more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X780S 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 SAU63X780S 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 SU63X780S Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways across a 780mm gap using the 1559N push force at 0.5MPa, requiring external guides to prevent rod bending.
Ejector Assembly
Cycles at 30-800mm/s to eject formed parts from a press, relying on the 21mm adjustable air cushions at both ends to decelerate the 63mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X780S with the SAU63X780S
To replace this discontinued SU63X780S, order the SAU63X780S, confirming the 63mm bore, 780mm stroke, 3/8" port, and default PT threads. If sizing alternatives, neighboring bores offer different force classes: a 50mm bore provides 982N push at 0.5MPa, while an 80mm bore yields 2513N. For the 780mm stroke, external guides are strongly recommended to prevent rod bending and side-load damage. Remember that a plain cylinder drifts without live air—the cushions only decelerate near stroke ends—so use an external rod lock or pilot-operated check valve for load holding. Finally, migrate your -S magnet sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG, and consider the SAUF valve-integrated variant if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X780S
- ✓ 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 SU63X780S FAQ
Yes, the AirTAC SU63X780S is discontinued. The direct replacement is the SAU63X780S, which matches the 63mm bore, 780mm stroke, 1559N force at 0.5MPa, 3/8" port, 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 magnet model, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
