This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1030STC, 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 SU32~50 Standard Cylinder SU50X1030STC
The AirTAC SU32~50 Standard Cylinder SU50X1030STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 1030mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1030STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1030STC
The AirTAC SU50X1030STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 1030mm stroke. Delivering 982 N push force at 0.5 MPa, it features a 1/4" port, M16x1.5 rod thread, and an integrated magnet for legacy CS1-B/DS1-B switches. The direct replacement is the SAU50X1030STC, preserving the original body, stroke, force, port, and SC-series TC mounting.
Because the 1030mm stroke exceeds the 1200mm standard limit, it is a nonstandard stroke requiring careful external guidance to prevent rod bending. The SAU upgrade transitions sensors to the current CMSG/DMSG/EMSG family and introduces the SAUF built-in-valve option.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X1030STC 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 SU32~50 Standard Cylinder SU50X1030STC Is Used
Long-Reach Diversion
Pushes packages across a wide conveyor belt using the 1030mm stroke, relying on the 982 N push force at 0.5 MPa to redirect heavy cartons smoothly.
High-Bay Ejection
Extends deep into storage racking to eject totes, requiring an external guide to prevent rod bending over the long 1030mm travel distance.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1030STC with the SAU50X1030STC
To replace this discontinued SU50X1030STC, order the SAU50X1030STC. Confirm the 50mm bore, 1030mm stroke, 1/4" port (default PT), M16x1.5 rod thread, and TC mounting interface. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensors on the SAU. Neighbouring bores offer alternatives: a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. At 1030mm, this long cylinder requires an external guide to prevent rod bending under side loads. A plain cylinder does not hold load without live air; the cushion only decelerates, so use an external rod lock or pilot-operated check valve for vertical holding. If valve integration is needed, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1030STC
- ✓ 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 SU32~50 Standard Cylinder SU50X1030STC FAQ
Yes, the SU50X1030STC is discontinued. The direct replacement is the SAU50X1030STC. It shares the same 50mm bore, 1030mm stroke, 982 N push force at 0.5 MPa, 1/4" port, and TC mounting, fitting the same application directly.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
