This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X330, 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 SU63X330
The AirTAC Airtac SU63-100 Standard Cylinder SU63X330 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 SAU63X330, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X330
The AirTAC SU63X330 is a discontinued double-acting profile-type cylinder featuring a 63mm bore and 330mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X330, a direct alternative retaining the exact body, stroke, force, port, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option. Because this specific SKU lacks a magnet (-S), it cannot accept any sensor. The cushion only decelerates; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X330 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 SAU63X330 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 SU63X330 Is Used
Package Diverting
Pushes medium-weight cartons off a main belt line, utilising the 1559N push force to overcome side friction over the 330mm travel.
Pallet Stop Gate
Acts as a pneumatic stop for incoming pallets on a gravity roller track, absorbing kinetic energy via the adjustable 21mm cushions.
Component Ejection
Ejects machined aluminium parts from a fixture, where the 1402N pull force safely retracts the mechanism despite tooling weight.
Replacing the Airtac SU63-100 Standard Cylinder SU63X330 with the SAU63X330
To replace the SU63X330, order the SAU63X330, confirming the 3/8" port, M16x1.5 rod thread, and SC-series mounting. If stepping up or down, the 50mm bore offers 982N push while the 80mm provides 2513N at 0.5MPa. This 330mm length requires external guides to prevent rod bending under side loads. As a non-magnetic SKU, it cannot take a switch; the SAU replacement uses CMSG/DMSG/EMSG sensors if you add the -S option. For load holding on air loss, add a pilot-operated check valve, as cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU63X330
- ✓ 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 SU63X330 FAQ
Yes, the SU63X330 is discontinued. The direct replacement is the AirTAC SAU63X330. It matches the 63mm bore, 330mm stroke, 1559N force, 3/8" port, and SC-series mounting accessories, so it drops into the same application. The SAU also adds a SAUF built-in-valve option.
At 0.5MPa it pushes 1559N and pulls 1402N; at 0.7MPa push is 2182N; theoretical max is 318kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot take a sensor. If sensing is needed, the SAU replacement with the -S option uses current CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B).
