This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X70, 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 SU80X70
The AirTAC Airtac SU63-100 Standard Cylinder SU80X70 is a double-acting profile-type standard cylinder with a Ø80mm bore and 70mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X70, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X70
The AirTAC SU80X70 is a discontinued double-acting profile-type cylinder with an 80mm bore and 70mm stroke. It delivers 2513N push and 2268N pull force at 0.5MPa, utilizing a 3/8" port and a Ø25mm piston rod. AirTAC replaced this legacy unit with the SAU80X70, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SU SKU lacks a magnet, it cannot accept position sensors; furthermore, the SAU upgrade switches to current CMSG/DMSG/EMSG switches from the old CS1-B/DS1-B family. The extruded aluminium profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X70 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 SAU80X70 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 SU80X70 Is Used
Press Fit Tooling
Applies steady 2513N thrust at 0.5MPa to seat bearings and bushings into machined housings without an oversized footprint.
Package Diverters
Drives mechanical diverter arms on packaging lines, using adjustable end cushions to soften stops at high cycle speeds.
Replacing the Airtac SU63-100 Standard Cylinder SU80X70 with the SAU80X70
To replace the discontinued SU80X70, order the SAU80X70 and confirm the 3/8" port, M20x1.5 rod thread, PT thread type, and SC-series mounting (LB/FA/FB/CA/CB). Since this specific SKU has no magnet (-S), it cannot support sensing; if you need position feedback, the SAU replacement requires CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. When sizing, a neighboring 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore offers 3927N. For load holding, note that a standard cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for secure holding. The SAUF variant also adds a built-in 4M solenoid valve the SU line lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU80X70
- ✓ 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 SU80X70 FAQ
Yes, the AirTAC SU80X70 is discontinued. The direct replacement is the SAU80X70, which shares the identical 80mm bore, 70mm stroke, 3/8" port, force, and SC-series mounting.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa it pushes 3518N, with a theoretical max of 513kgf at 1.0MPa. It cannot hold a load without live air—the cushion only decelerates—so use an external rod lock for holding.
