This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X330S, 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 SU63X330S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X330S is a double-acting profile-type standard cylinder with a Ø63mm bore and 330mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X330S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X330S
The AirTAC SU63X330S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 330 mm stroke. Delivering 1559 N push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced it with the SAU63X330S, a direct upgrade retaining the exact bore, stroke, output force, 3/8" port, and SC-series mounting.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X330S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X330S 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 SU63X330S Is Used
Pallet Diversion
Uses the 1559 N push force at 0.5 MPa to deflect heavy pallets along a sorting line without overwhelming the compact profile body.
Clamp Actuation
Secures large workpieces in machining fixtures, relying on adjustable 21 mm end cushions to decelerate the heavy 63 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X330S with the SAU63X330S
To replace this discontinued SU63X330S, order the SAU63X330S. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) carry over directly. If downsizing, a 50 mm bore gives 982 N push at 0.5 MPa; if upsizing, an 80 mm bore yields 2513 N. The -S magnet means you must swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAU. At 330 mm stroke, prevent rod bending by supporting the load against side-load with an external guide. Note that air cushions only decelerate the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X330S
- ✓ 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 SU63X330S FAQ
Yes, the SU63X330S is end-of-life. The direct replacement is the AirTAC SAU63X330S. It shares the identical 63 mm bore, 330 mm stroke, output force, 3/8" port, and SC-series mounting, so it bolts right in. The only change is that your legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors.
The 63 mm bore has a 3/8" port. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. The piston rod is 20 mm with an M16x1.5 thread, and speed ranges from 30-800 mm/s.
