This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X35CA, 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 SU80X35CA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X35CA is a double-acting profile-type standard cylinder with a Ø80mm bore and 35mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X35CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X35CA
The AirTAC SU80X35CA is a discontinued double-acting profile-type cylinder. It delivers 2513 N push and 2268 N pull at 0.5 MPa, utilizing an 80 mm bore and a 25 mm piston rod. AirTAC replaced this legacy unit with the SAU80X35CA. This direct upgrade preserves the exact 35 mm stroke, 513 kgf maximum force, 3/8" port, and SC-series CA mounting, ensuring a seamless retrofit into your existing machinery.
The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor; furthermore, the SAU family upgrades the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors and introduces a SAUF built-in 4M solenoid valve option the SU line never had.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X35CA 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 SU80X35CA Is Used
Press Tool Ejection
Supplies 2513 N of push at 0.5 MPa to eject heavy stamped parts from press dies, using the 35 mm short stroke for rapid, high-force ejection cycles.
Pallet Diverter
Actuates a heavy-duty diverter arm on a packaging line, relying on the compact profile body and CA clevis mount to fit within tight conveyor frame clearances.
Replacing the Airtac SU63-100 Standard Cylinder SU80X35CA with the SAU80X35CA
To replace the SU80X35CA, order the SAU80X35CA and verify your 80 mm bore, 35 mm stroke, 3/8" port (default PT thread), and M20x1.5 rod-end thread. The SC-series CA clevis mount carries over directly. If sizing a new build, the 80 mm bore yields 2513 N push at 0.5 MPa; dropping to a 63 mm bore reduces push to 1559 N, while an 100 mm bore increases it to 3927 N. Since this non-magnetic SKU cannot accept a switch, sensing requires external physical targets. Note that the air cushion only decelerates the piston near stroke end; it does not hold the load. For vertical or suspended loads that must resist drift on air loss, install an external rod lock or pilot-operated check valve. If space allows, the SAUF variant integrates a 4M solenoid valve directly onto the body for faster cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU80X35CA
- ✓ 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 SU80X35CA FAQ
Yes, the AirTAC SU80X35CA is discontinued. The direct replacement is the SAU80X35CA. It matches the 80 mm bore, 35 mm stroke, 2513 N push force at 0.5 MPa, 3/8" port, and SC-series CA mounting. The extruded aluminum body and adjustable cushions are identical, so it drops right into the same footprint.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept a magnetic switch. If you need sensing on the SAU replacement, order an -S version and note that the SAU family uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
