This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X30, 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 SU63X30
The AirTAC Airtac SU63-100 Standard Cylinder SU63X30 is a double-acting profile-type standard cylinder with a Ø63mm bore and 30mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X30, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X30
The AirTAC SU63X30 is a discontinued double-acting profile-type cylinder with a 63mm bore and 30mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X30, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
Because the extruded aluminum body lacks external rods, it is more compact than an ISO 15552 cylinder of the same size. Note that this non-magnetic SKU cannot accept a sensor, and the SAU upgrade switches to CMSG/DMSG/EMSG switches for -S variants. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X30 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 SAU63X30 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 SU63X30 Is Used
Short-Stroke Clamping
Ideal for holding heavy castings during machining, utilizing the 1559N push force within a tight 30mm stroke to secure parts firmly without excessive travel.
Package Diverting
Provides robust actuation for routing heavier pallets or goods on a production line, where the compact profile body saves valuable machine space.
Replacing the Airtac SU63-100 Standard Cylinder SU63X30 with the SAU63X30
To replace this discontinued SU63X30, order the SAU63X30. Verify your 3/8" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC) which carry over directly. This non-magnetic SKU cannot accept a sensor; if you need position detection on the SAU, order the -S variant and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing down, a 50mm bore provides 982N push at 0.5MPa; sizing up, an 80mm bore yields 2513N. Remember that a plain cylinder drifts without live air—the cushions only decelerate at end-of-stroke, so add an external rod lock or pilot-operated check valve for load holding. For short 30mm strokes, side-load is minimal, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU63X30
- ✓ 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 SU63X30 FAQ
Yes, the AirTAC SU63X30 is discontinued and end-of-life. The direct replacement is the SAU63X30. It shares the same 63mm bore, 30mm stroke, 1559N force at 0.5MPa, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it pushes 1559N and pulls 1402N; at 0.7MPa it pushes 2182N, with a theoretical max of 318kgf at 1.0MPa. This specific non-magnetic SKU cannot accept a sensor. If sensing is required on the SAU replacement, you must order the -S version, which uses current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B.
