This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X730TC, 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 SU63X730TC
The AirTAC SU63-100 Standard Cylinder SU63X730TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 730mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X730TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X730TC
The AirTAC SU63X730TC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 730 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this EOL unit with the SAU63X730TC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this specific SKU lacks a magnet, it cannot accept a piston sensor. The SAU replacement modernizes sensing via CMSG/DMSG/EMSG switches on magnetized variants, and introduces the SAUF built-in 4M valve option absent in the SU line. Note that standard air cushions only decelerate the load; they do not hold it without live air.

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 SAU63X730TC 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 SU63X730TC Is Used
Long-Stroke Diverting
Pushes heavy pallets laterally across transfer lines using the 1559 N push force and 730 mm reach, requiring external guides to absorb side loads.
Large Press Ejection
Cycles formed parts out of heavy machinery beds, utilizing the adjustable 21 mm cushions at both ends to decelerate the 730 mm travel smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X730TC with the SAU63X730TC
To replace this discontinued SU63X730TC, order the SAU63X730TC. Verify your 3/8" port, M16x1.5 rod thread, and TC mounting accessory are retained. If stepping down to a 50 mm bore yields 982 N push (often insufficient), the 80 mm bore offers 2513 N if your frame allows. This 730 mm stroke requires external guide rails to prevent rod bending under side loads. Since this non-magnetic SKU cannot host a sensor, adding a magnet to the SAU requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. The SAUF valve-integrated variant is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X730TC
- ✓ 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 SU63X730TC FAQ
Yes, the SU63X730TC is discontinued. The direct replacement is the AirTAC SAU63X730TC. It matches the 63 mm bore, 730 mm stroke, 3/8" port, output force, and TC mounting, fitting the same application without mechanical modifications.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot take a sensor; magnetized SAU replacements use CMSG/DMSG/EMSG switches.
