This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X135S, 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 SU80X135S
The AirTAC SU63-100 Standard Cylinder SU80X135S is a double-acting profile-type standard cylinder with a Ø80mm bore and 135mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X135S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X135S
The AirTAC SU80X135S is a discontinued double-acting profile-type cylinder with an 80mm bore and 135mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its direct replacement is the SAU80X135S, matching the force, 3/8" port, M20x1.5 rod thread, and SC-series mounting. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.
Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M valve option the SU lacked. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X135S 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 SAU80X135S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×135 | 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 SU80X135S Is Used
Mid-Tonnage Pressing
Applies the 3518N push at 0.7MPa for seating bearings or light stamping tasks within a 135mm travel.
Pallet Diversion
Drives heavy-duty lane deflector gates on packaging lines, utilising the compact profile body to save space.
Vertical Lift Stops
Lifts or halts goods up to 128kg safely, benefiting from the 28mm adjustable end cushions to prevent end-cap impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X135S with the SAU80X135S
To replace this SU80X135S, order the SAU80X135S direct equivalent, verifying the 135mm stroke, 3/8" port, and PT/G/NPT thread choice. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore provides 3927N. The -S magnet means you must migrate from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. The 28mm adjustable cushions only decelerate the load, so fit a pilot-operated check valve or rod lock if the load must be held. For faster actuation, consider the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X135S
- ✓ 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 SU80X135S FAQ
Yes, the AirTAC SU80X135S is discontinued. The direct replacement is the SAU80X135S, which shares the identical 80mm bore, 135mm stroke, 513kgf max force, 3/8" port, and SC-series mounting accessories.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa it pushes 3518N, with a theoretical max of 513kgf at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
