This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X70SCA, 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 SU63X70SCA
The AirTAC Airtac SU63-100 Standard Cylinder SU63X70SCA is a double-acting profile-type standard cylinder with a Ø63mm bore and 70mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X70SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X70SCA
The AirTAC SU63X70SCA is a discontinued double-acting profile-type standard cylinder with a 63 mm bore and 70 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X70SCA, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series CA mounting accessory.
Because the extruded aluminum body has no external rods, it is shorter and more compact than an ISO 15552 cylinder of the same bore. The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this SU -S magnet model, and adds the SAUF built-in 4M solenoid valve option the SU line never had.

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 SAU63X70SCA 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 SU63X70SCA Is Used
Clamp Actuation
Drives 79 kg vertical clamping arms in machining fixtures using the 1559 N push force at 0.5 MPa.
Package Diverting
Pivots heavy cartons on packaging lines via the CA clevis mount, absorbing side loads during transit.
Pallet Lift Gates
Raises and lowers 70 mm stroke safety gates at logistics stations, benefitting from the compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X70SCA with the SAU63X70SCA
To replace this discontinued SU63X70SCA, order the SAU63X70SCA and verify your 3/8" port, M16x1.5 rod thread, and CA mounting interface. The SC-series CA clevis mount is reused directly. If moving to a neighboring bore, note the 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore yields 2513 N. This cylinder does not hold load on air loss; the 21 mm adjustable cushions only decelerate near stroke ends, so add an external rod lock or pilot-operated check valve for vertical holding. If you relied on the -S magnet, you must upgrade to CMSG/DMSG/EMSG switches. For automated actuation, consider the SAUF variant with its integrated valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X70SCA
- ✓ 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 SU63X70SCA FAQ
Yes, the SU63X70SCA is discontinued. The direct replacement is the SAU63X70SCA. It matches the 63 mm bore, 70 mm stroke, 1559 N force, 3/8" port, and SC-series CA mounting. The body dimensions remain identical, but the SAU uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
At 0.5 MPa it provides 1559 N push and 1402 N pull force. At 0.7 MPa push is 2182 N, and at 0.9 MPa it is 2805 N. The theoretical maximum is 318 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and the 21 mm cushions only decelerate the load; they do not hold it without live air.
