This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X600STC, 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 SU63X600STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X600STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X600STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X600STC
The AirTAC SU63X600STC is a discontinued double-acting profile cylinder with a 63 mm bore and 600 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a theoretical 318 kgf. AirTAC replaced this unit with the SAU63X600STC, a direct sharing the exact 3/8" port, M16x1.5 rod thread, and SC-series TC mounting interface.
The SAU upgrade retains the compact extruded aluminium body but modernises the sensor groove. Your original -S magnet used legacy CS1-B/DS1-B switches, whereas the SAU takes current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X600STC 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 SAU63X600STC 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 SU63X600STC Is Used
Pallet Diversion
Shifts heavy pallets transversely on a packaging line using the 1559 N push force at 0.5 MPa over a 600 mm travel distance.
Component Ejection
Pushes machined metal parts out of a CNC enclosure, requiring the full 600 mm extension to clear the work zone safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X600STC with the SAU63X600STC
To replace this discontinued SU63X600STC, order the SAU63X600STC ensuring your 3/8" port, M16x1.5 thread, and TC mounting match. Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. If you need integrated flow control, the SAU family offers the SAUF built-in-valve variant the SU lacked. For loads needing 2805 N at 0.9 MPa, the 80 mm bore provides the next step up, while the 50 mm offers 982 N at 0.5 MPa. At 600 mm stroke, prevent rod bending by supporting the load with an external guide. A plain cylinder drifts on air loss; the cushion only decelerates, so use a pilot-operated check valve or rod lock for holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X600STC
- ✓ 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 SU63X600STC FAQ
Yes, the AirTAC SU63X600STC is end-of-life. The direct replacement is the SAU63X600STC. It matches the 63 mm bore, 600 mm stroke, 318 kgf max force, 3/8" port, and TC mounting. You simply order the SAU equivalent.
It pushes 1559 N and pulls 1402 N at 0.5 MPa, pushes 2182 N at 0.7 MPa, and reaches 2805 N at 0.9 MPa. The -S magnet on this legacy SU works with CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
