This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X405S, 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 SU80X405S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X405S is a double-acting profile-type standard cylinder with a Ø80mm bore and 405mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X405S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X405S
The AirTAC SU80X405S is a discontinued double-acting profile-type cylinder with an 80mm bore and 405mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a 3/8" port. The direct replacement is the SAU80X405S, matching the bore, stroke, force, port, and SC-series mounting.
This extruded aluminium body is shorter than an ISO 15552 equivalent. The SAU upgrade switches the -S magnet from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors, and adds the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X405S 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 SAU80X405S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X405S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×405 | 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 SU80X405S Is Used
Pallet Diversion
Pushes heavy pallets sideways onto parallel conveyor lines using the 2513N push force at 0.5MPa.
Press Ejection
Ejects dense formed parts from a press bed, relying on the adjustable 28mm cushions to stop smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X405S with the SAU80X405S
To replace this SU80X405S, order the SAU80X405S direct: verify the 80mm bore, 405mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing neighbours, a 63mm bore gives 1559N [email protected], while a 100mm bore gives 3927N. For this 405mm stroke, use external guides to prevent rod bending under side loads. The air cushion only decelerates; for load holding on air loss, fit an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X405S
- ✓ 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 SU80X405S FAQ
Yes, the SU80X405S is discontinued. The direct replacement is the SAU80X405S. It matches the 80mm bore, 405mm stroke, 2513N force, 3/8" port, and SC-series mounting. The SAU body also adds the SAUF built-in-valve option the SU lacked.
It pushes 2513N and pulls 2268N at 0.5MPa, pushes 3518N at 0.7MPa, and reaches a 513kgf max at 1.0MPa. Because this is an -S magnet model, the old CS1-B/DS1-B switches are retired; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
