This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X140S, 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 SU80X140S
The AirTAC SU63-100 Standard Cylinder SU80X140S is a double-acting profile-type standard cylinder with a Ø80mm bore and 140mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X140S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X140S
The AirTAC SU80X140S is a discontinued double-acting profile-type cylinder with an 80mm bore and 140mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa. AirTAC replaced this EOL unit with the SAU80X140S, a direct alternative matching the 3/8 port, M20x1.5 rod thread, 28mm cushions, and SC-series mounting footprint.
The extruded aluminium body is shorter than an equivalent ISO 15552 unit. Because this SKU includes the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in 4M valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X140S 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 SAU80X140S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×140 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU80X140S Is Used
Press Tool Ejection
Provides robust 2513N push force at 0.5MPa to eject stamped parts from heavy press dies, utilizing the 140mm stroke to clear the tooling bed safely.
Pallet Diverting
Handles robust side-load diverting of heavy goods pallets on roller lines, where the 80mm bore output and compact profile body fit neatly within transfer gaps.
Replacing the Airtac SU63-100 Standard Cylinder SU80X140S with the SAU80X140S
To replace this SU80X140S, order the SAU80X140S direct equivalent, verifying your 3/8 port thread (PT/G/NPT) and SC-series mounting hardware (LB/FA/FB/CA/CB). The -S magnet means you must migrate from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. If sizing neighbours, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Remember this cylinder drifts without live air; the cushions only decelerate, so use an external rod lock or pilot-operated check valve for held loads. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X140S
- ✓ 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 SU80X140S FAQ
Yes, the AirTAC SU80X140S is discontinued and end-of-life. The direct replacement is the SAU80X140S. It shares the identical 80mm bore, 140mm stroke, 2513N output force at 0.5MPa, 3/8 port, and SC-series mounting accessories.
The 80mm bore yields 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. Because your SU has the -S magnet, note the SAU replacement switches from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
