This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X350H, 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 SU80X350H
The AirTAC SU63-100 Standard Cylinder SU80X350H 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 SAU80X350H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X350H
The AirTAC SU80X350H is a discontinued double-acting profile-type cylinder with an 80mm bore and 350mm stroke. It delivers 2513N push force at 0.5MPa via a 3/8" port. The direct replacement is the SAU80X350H, matching the bore, stroke, force, port, and SC-series mounting. This -H variant specifies a Viton FKM seal for 0-150C high-temperature environments.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade also adds the SAUF valve-integrated option the SU line lacked. Note that the 350mm stroke requires an external guide to prevent rod bending under side loads.

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 SAU80X350H 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 SU80X350H Is Used
Hot Stamp Press Ejection
Handles high-temperature part ejection from stamping presses, utilizing the Viton -H seal to withstand radiant heat while providing 2513N of push force at 0.5 MPa.
Long-Transfer Diversion
Actuates heavy diverter arms over 350mm of travel on packaging lines, requiring external guides to prevent rod bending during lateral pallet redirection.
Replacing the Airtac SU63-100 Standard Cylinder SU80X350H with the SAU80X350H
To replace this SU80X350H, order the SAU80X350H. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting hardware—everything drops in mechanically. The -H Viton seal is retained for 150C heat. Since this SKU has no magnet, you cannot mount sensors; if you need position detection on the SAU, specify the -S option and migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For the 350mm stroke, add an external guide to absorb side loads and prevent rod bending. If sizing down, a 63mm bore gives 1559N push at 0.5MPa; sizing up to 100mm yields 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X350H
- ✓ 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 SU80X350H FAQ
Yes, the AirTAC SU80X350H is discontinued and end-of-life. The direct replacement is the SAU80X350H. It shares the exact same 80mm bore, 350mm stroke, 2513N output force at 0.5MPa, 3/8" port, and SC-series mounting accessories. You also retain the high-temperature Viton seal option for 0-150C environments.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa push is 3518N, and the theoretical maximum is 513kgf at 1.0MPa. This specific SKU has no magnet (-S), so it cannot accept magnetic switches like the legacy CS1-B/DS1-B. If you need sensing on the SAU replacement, you must order the -S version and use current CMSG/DMSG/EMSG sensors.
