This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X70, 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 SU63X70
The AirTAC SU63-100 Standard Cylinder SU63X70 is a double-acting profile-type standard cylinder with a Ø63mm bore and 70mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X70, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X70
The AirTAC SU63X70 is a discontinued double-acting profile cylinder with a 63mm bore and 70mm stroke. Delivering 1559N push force at 0.5MPa via a 3/8 inch port, it is directly replaced by the SAU63X70. The SAU is a direct upgrade, matching the exact body, stroke, output force, and SC-series mounting.
Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is required, the SAU replacement uses modern CMSG/DMSG/EMSG switches (the SU line relied on legacy CS1-B/DS1-B). The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the original SU never offered. The extruded aluminum profile remains shorter and more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X70 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 SAU63X70 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 SU63X70 Is Used
Package Diverting
Actuates routing gates on packaging lines, using the 1559N thrust to push heavy cartons smoothly onto adjacent chutes.
Clamping Fixtures
Secures steel plates during machining operations, providing reliable 1402N pull force to hold workpieces firmly against stops.
Pallet Stops
Controls pallet flow on roller conveyors, raising a 63mm profile barrier to halt inbound loads weighing up to 79kg safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X70 with the SAU63X70
To replace the discontinued SU63X70, order the SAU63X70. Confirm the 3/8 inch port, M16x1.5 rod thread, and your SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Since this SKU has no magnet, it cannot support a sensor; if you need position detection, specify an SAU63X70-S and upgrade to CMSG/DMSG/EMSG switches. For sizing, the 63mm bore provides 1559N push and 1402N pull at 0.5MPa; if less force is needed, a 50mm bore offers 982N push, while an 80mm bore provides 2513N. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so use an external rod lock or pilot-operated check valve for load holding. At 70mm stroke, side-load risks are minimal, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU63X70
- ✓ 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 SU63X70 FAQ
Yes, the AirTAC SU63X70 is discontinued and end-of-life. The direct replacement is the SAU63X70. It shares the same 63mm bore, 70mm stroke, 3/8 inch port, output force, and SC-series mounting, so it fits the same application without modification.
The 63mm bore generates 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. If you need sensing, order the SAU replacement with an -S option, which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
