This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X700S, 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 SU80X700S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X700S is a double-acting profile-type standard cylinder with a Ø80mm bore and 700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X700S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X700S
The AirTAC SU80X700S is a discontinued double-acting profile-type cylinder with an 80mm bore and 700mm stroke. AirTAC replaced this legacy unit with the SAU80X700S, a direct alternative retaining the exact 3/8" port, M20x1.5 rod thread, 25mm piston rod, and SC-series mounting hardware.
Because this SKU includes the -S magnet, it originally used CS1-B/DS1-B switches; the SAU replacement transitions to the current CMSG/DMSG/EMSG sensor family. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore, and the adjustable 28mm air cushions at both ends strictly decelerate the piston rather than holding the load.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X700S 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 SAU80X700S 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 SU80X700S Is Used
Heavy Carton Diversion
Pushes heavy palletized cartons on a high-speed packaging line using the 2513N thrust at 0.5MPa, with the 700mm stroke reaching across a wide conveyor belt.
Pallet Stopper Gate
Acts as a robust pneumatic stop for inbound warehouse pallets, utilizing the 128kg vertical lift capacity and 28mm adjustable cushions to halt loads smoothly.
Large Press Ejection
Ejects formed metal parts from an 80-ton press, where the compact extruded profile saves space and the 700mm extension clears the large machine bed.
Replacing the Airtac SU63-100 Standard Cylinder SU80X700S with the SAU80X700S
To replace this discontinued SU80X700S, order the SAU80X700S, confirming the 80mm bore, 700mm stroke, 3/8" port, and PT/G/NPT thread choice. Reuse your existing SC-series mounts (LB/FA/FB/CA/CB). Since this is an -S model, note the mandatory sensor swap: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. If sizing down, a 63mm bore gives 1559N push at 0.5MPa; if sizing up, a 100mm bore yields 3927N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushions only decelerate. At 700mm stroke, use an external guide to prevent rod bending and side-load damage. The SAUF valve-integrated option can simplify cycling if you lack a separate solenoid.
Replacement checklist
- ✓ Same bore / stroke → SAU80X700S
- ✓ 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 SU80X700S FAQ
Yes, the SU80X700S is discontinued. The direct replacement is the AirTAC SAU80X700S. It matches the 80mm bore, 700mm stroke, 2513N push force at 0.5MPa, 3/8" port, and SC-series mounting accessories. You can swap it directly without altering your mechanical footprint.
This 80mm bore cylinder provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N at 0.9MPa, and a 513kgf maximum at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to current CMSG/DMSG/EMSG sensors.
