This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X620, 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 SU63X620
The AirTAC Airtac SU63-100 Standard Cylinder SU63X620 is a double-acting profile-type standard cylinder with a Ø63mm bore and 620mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X620, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X620
The AirTAC SU63X620 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 620 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and shares AirTAC SC-series mounting accessories.
AirTAC replaced this end-of-life unit with the SAU63X620, a direct upgrade retaining the exact bore, stroke, output force, 3/8" port, M16x1.5 rod thread, and SC-series mounting. The SAU brings current CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches, and introduces the SAUF built-in 4M solenoid valve variant the SU line never had. Note this specific SKU lacks a magnet and cannot accept sensing switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X620 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 SAU63X620 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 SU63X620 Is Used
Long-Stroke Diverting
Pushes products across transfer lanes using the full 620 mm travel, relying on the 1559 N thrust to overcome friction on moving belts without stalling.
External Guide Ejection
Ejects machined parts from a fixture, demanding strict external linear guides to prevent rod bending over the 620 mm extension under side-load conditions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X620 with the SAU63X620
To replace this discontinued SU63X620, order the SAU63X620, confirming the 63 mm bore, 620 mm stroke, 3/8" port, and PT/G/NPT thread choice. Because this SKU has no -S magnet, it cannot support position sensing; if detection is needed, specify an -S SAU model and use the new CMSG/DMSG/EMSG switch family rather than the older CS1-B/DS1-B. Operating at 0.5 MPa provides 1559 N push and 1402 N pull force; if you need less thrust, step down to a 50 mm bore (982 N push), or step up to an 80 mm bore (2513 N push) for heavier loads. For the 620 mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. A plain cylinder drifts on air loss—the cushions only decelerate near stroke end—so fit an external rod lock or pilot-operated check valve for secure load holding. The SAUF valve-integrated option can also simplify cycle control.
Replacement checklist
- ✓ Same bore / stroke → SAU63X620
- ✓ 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 SU63X620 FAQ
Yes, the SU63X620 is discontinued. The direct replacement is the AirTAC SAU63X620. It matches the original 63 mm bore, 620 mm stroke, 1559 N force at 0.5 MPa, 3/8" port, and SC-series mounting. You also gain the option of the SAUF variant with a built-in 4M solenoid valve.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N, and the theoretical maximum is 318 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take sensors; if you need detection, order the SAU replacement with an -S option, which uses the current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
