This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X150STC, 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 SU63X150STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X150STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X150STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X150STC
The AirTAC SU63X150STC is a discontinued double-acting profile-type cylinder featuring a 63mm bore and 150mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, utilizing a 3/8" port and an M16x1.5 rod thread. AirTAC replaced this legacy unit with the SAU63X150STC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
When upgrading, note that the SAU series modernizes the sensor groove to accept current CMSG/DMSG/EMSG switches, whereas this SU model's magnet was designed for legacy CS1-B/DS1-B units. The extruded aluminum profile is more compact than a standard ISO 15552 cylinder of the same bore.

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 SAU63X150STC 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 SU63X150STC Is Used
Package Diverting
Pushes parcels off a main transport line using 1559 N of thrust at 0.5 MPa, with the TC mount providing a rigid pivot for lateral sweeping motions.
Clamp Actuation
Secures medium-weight steel extrusions in a machining fixture, using the 318 kgf maximum theoretical force to prevent shifting during drilling.
Replacing the Airtac SU63-100 Standard Cylinder SU63X150STC with the SAU63X150STC
To replace the discontinued SU63X150STC, order the SAU63X150STC, matching the 63mm bore, 150mm stroke, 3/8" port, and TC mounting. Because this SKU includes a magnet (-S), you must switch from the old CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG sensors. If sizing alternatives, a 50mm bore provides 982 N push at 0.5 MPa, while an 80mm bore yields 2513 N. Note that a plain cylinder drifts without live air; the adjustable cushion only decelerates the piston, so use an external rod lock or pilot-operated check valve for load holding. For applications needing integrated control, explore the SAUF variant featuring a built-in 4M solenoid valve not available in the SU line.
Replacement checklist
- ✓ Same bore / stroke → SAU63X150STC
- ✓ 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 SU63X150STC FAQ
Yes, the SU63X150STC is discontinued. The direct replacement is the AirTAC SAU63X150STC. It shares the identical 63mm bore, 150mm stroke, 3/8" port, and TC mounting hardware, meaning it bolts directly into the same space without mechanical modifications.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, and the theoretical maximum is 318 kgf at 1.0 MPa. Because this is an -S magnet model, it originally used CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
