This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X290S, 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 SU80X290S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X290S is a double-acting profile-type standard cylinder with a Ø80mm bore and 290mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X290S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X290S
The AirTAC SU80X290S is a discontinued double-acting profile-type cylinder with an 80mm bore and 290mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a 3/8" port. The direct replacement is the SAU80X290S, matching the bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade retains the compact extruded aluminum body but switches the -S magnet sensor compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X290S 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 SAU80X290S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×290 | 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 SU80X290S Is Used
Pallet Diversion
Pushes heavy pallets transversely off a high-throughput conveyor line using the 2513 N push force at 0.5 MPa.
Press Ejection
Ejects dense metal stampings from a press bed, utilizing the 28 mm adjustable air cushions to decelerate the rod.
Replacing the Airtac SU63-100 Standard Cylinder SU80X290S with the SAU80X290S
To replace this SU80X290S with the SAU80X290S, verify the 80mm bore, 290mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB/TC). Because the -S magnet is present, note that the SAU requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. Sizing both ways: a 63mm bore offers 1559 N push @0.5 MPa, while a 100mm bore yields 3927 N. For this 290mm stroke, ensure adequate guide support to prevent rod bending under side loads. A plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding. If self-switching is needed, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X290S
- ✓ 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 SU80X290S FAQ
Yes, the SU80X290S is discontinued. The direct replacement is the SAU80X290S, which shares the same 80mm bore, 290mm stroke, 3/8" port, output force, and SC-series mounting accessories.
It provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
