This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X750, 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 SU63X750
The AirTAC SU63-100 Standard Cylinder SU63X750 is a double-acting profile-type standard cylinder with a Ø63mm bore and 750mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X750, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X750
The AirTAC SU63X750 is a discontinued double-acting profile-type cylinder with a 63mm bore and 750mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8 inch port, using an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU63X750 direct replacement, which matches the exact stroke, force, port size, and SC-series mounting.
This specific SKU lacks a magnet, so it cannot accept a sensor; the SAU upgrade also drops the legacy CS1-B/DS1-B switches for modern CMSG/DMSG/EMSG sensors on its -S variants. Note that a plain cylinder drifts without live air, so use an external rod lock for holding.

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 SAU63X750 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 SU63X750 Is Used
Long-Stroke Diverting
Pushes packages across a 750mm conveyor lane using the 1559N thrust at 0.5MPa, guided externally to prevent rod bending.
Pallet Stopper Arm
Acts as a 63mm bore stopper on a pallet flow line, dropping in seamlessly using existing SC-series mounting brackets.
Replacing the Airtac SU63-100 Standard Cylinder SU63X750 with the SAU63X750
To replace this SU63X750 with the SAU63X750, verify the 63mm bore, 750mm stroke, 3/8 inch port, and M16x1.5 rod thread. Because this SKU has no magnet (-S), it cannot take a sensor; if you need position detection on the new SAU, order an -S model and migrate from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU line never offered. For loads needing secure holding, remember the air cushion only decelerates at stroke end and the piston will drift without live air—install a pilot-operated check valve or external rod lock. At 750mm, the 20mm rod is vulnerable to bending; always use an external guide to prevent side loads. If downsizing, a 50mm bore gives 982N push at 0.5MPa; if uprating, an 80mm bore yields 2513N.
Replacement checklist
- ✓ Same bore / stroke → SAU63X750
- ✓ 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 SU63X750 FAQ
Yes, the AirTAC SU63X750 is discontinued. The direct replacement is the SAU63X750, which shares the same 63mm bore, 750mm stroke, 1559N force, 3/8 inch port, and SC-series mounting.
It provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants.
