This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X145S, 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 SU80X145S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X145S is a double-acting profile-type standard cylinder with a Ø80mm bore and 145mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X145S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X145S
The AirTAC SU80X145S is a discontinued double-acting profile-type cylinder with an 80mm bore and 145mm stroke. Delivering 2513N push force at 0.5MPa, its direct replacement is the SAU80X145S, preserving the original 3/8 inch port, M20x1.5 rod thread, and SC-series mounting compatibility.
This extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU successor upgrades to CMSG/DMSG/EMSG sensors and introduces a SAUF built-in 4M valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X145S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X145S 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 SU80X145S Is Used
Press Ejection
Uses the 2513N push force at 0.5MPa to reliably knock stamped parts out of a die, with the 145mm stroke clearing the press bed quickly.
Heavy Package Divert
Lateral sorting of dense cartons on a packing line where the 80mm bore provides enough thrust to push 128kg loads vertically or sideways without stalling.
Pallet Stopper Gate
Acts as a robust pneumatic stop on a roller conveyor, holding heavy pallets in place for wrapping before retracting to let them pass.
Replacing the Airtac SU63-100 Standard Cylinder SU80X145S with the SAU80X145S
To replace this discontinued SU80X145S, order the SAU80X145S ensuring your 3/8 inch port thread (PT/G/NPT) and SC-series mounting match. Because the -S magnet is present, note the mandatory sensor swap: old CS1-B/DS1-B switches must become CMSG/DMSG/EMSG on the new cylinder. For sizing both ways, a neighbouring 63mm bore yields 1559N [email protected], while an 100mm bore yields 3927N. A plain cylinder drifts without live air—the 28mm cushions only decelerate—so fit an external rod lock for held loads. The 145mm stroke avoids rod-bending risks, but always guide side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X145S
- ✓ 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 SU80X145S FAQ
Yes, the SU80X145S is discontinued. The direct replacement is the SAU80X145S. It shares the identical 80mm bore, 145mm stroke, 3/8 inch port, output force, and SC-series mounting, so it fits the same application. You simply order the SAU equivalent.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
