This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X350, 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 SU80X350
The AirTAC SU63-100 Standard Cylinder SU80X350 is a double-acting profile-type standard cylinder with a Ø80mm bore and 350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X350, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X350
The AirTAC SU80X350 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 350 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, making way for the exact SAU80X350 direct replacement. The SAU retains the identical extruded aluminium body, 3/8" port, M20x1.5 rod thread and SC-series mounting, ensuring a true mechanical direct.
Because this SKU lacks a magnet, it cannot accept a sensor; upgrading to the SAU also lets you adopt current CMSG/DMSG/EMSG switches on -S variants, plus the new SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X350 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 SAU80X350 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 SU80X350 Is Used
Pallet Diversion
Handles heavy pallet routing on packaging lines using the 2513 N push force, while the 350 mm stroke clears the lane for passage.
Press Ejection
Ejects formed metal parts from stamping presses, utilising the 28 mm adjustable cushions to decelerate the 80 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X350 with the SAU80X350
To replace the SU80X350, order the SAU80X350 direct: verify the 80 mm bore, 350 mm stroke, 3/8" port, M20x1.5 thread, and SC-series mounting. This non-magnetic SKU cannot take a switch; if you need sensing, specify an -S SAU and migrate from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For load holding, note that the cushion only decelerates; add an external rod lock or pilot-operated check valve to prevent drift on air loss. With a 350 mm stroke, use an external guide to prevent rod bending under side loads. If sizing neighbours, the 63 mm bore yields 1559 N push, while the 100 mm bore yields 3927 N at 0.5 MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU80X350
- ✓ 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 SU80X350 FAQ
Yes, the AirTAC SU80X350 is discontinued. The direct replacement is the SAU80X350, which shares the same 80 mm bore, 350 mm stroke, 3/8" port, output force, and SC-series mounting accessories.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. This specific SKU has no magnet and cannot accept a sensor; a plain cylinder also will not hold a load without live air, requiring an external rod lock for safety.
