This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X330, 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 SU80X330
The AirTAC SU63-100 Standard Cylinder SU80X330 is a double-acting profile-type standard cylinder with a Ø80mm bore and 330mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X330, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X330
The AirTAC SU80X330 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 330 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf. AirTAC replaced this end-of-line unit with the SAU80X330, a direct alternative retaining the exact 3/8" port, M20x1.5 rod thread, output force, and SC-series mounting footprint.
Because the 330 mm stroke exceeds 300 mm, use an external guide to prevent rod bending under side loads. This non-magnet SKU cannot accept a sensor, whereas the SAU replacement supports modern CMSG/DMSG/EMSG switches for -S builds. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X330 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 SAU80X330 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 SU80X330 Is Used
Pallet Diversion
Pushes heavy pallets sideways off a high-speed line using the 2513 N push force at 0.5 MPa, with the 330 mm stroke clearing the conveyor frame.
Press Ejection
Ejects dense stamped metal parts from a press bed, relying on adjustable 28 mm end cushions to decelerate the 80 mm piston smoothly at stroke ends.
Replacing the Airtac SU63-100 Standard Cylinder SU80X330 with the SAU80X330
To replace this discontinued SU80X330, order the SAU80X330 direct equivalent, verifying your 3/8" port, M20x1.5 thread, and SC-series mounting hardware. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore offers 3927 N. Since this is a non-magnet model, it cannot hold a switch; upgrading to an SAU-S allows CMSG/DMSG/EMSG sensors. For the 330 mm stroke, add external guides to absorb side loads and prevent rod bending. A plain cylinder drifts on air loss—the 28 mm cushions only decelerate—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated option can simplify actuation if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X330
- ✓ 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 SU80X330 FAQ
Yes, the SU80X330 is discontinued. The direct replacement is the AirTAC SAU80X330. It matches the 80 mm bore, 330 mm stroke, 2513 N push force at 0.5 MPa, 3/8" port, and SC-series mounting accessories. You can swap it directly without altering your mechanical layout.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, with a theoretical max of 513 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept sensors. If you need position detection, the SAU replacement with the -S option uses current CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B).
