This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1000STC, 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 SU50X1000STC
The AirTAC Airtac SU32~50 Standard Cylinder SU50X1000STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 1000mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1000STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1000STC
The AirTAC SU50X1000STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 1000mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers 982 N of push force at 0.5 MPa via a 1/4" port. AirTAC replaced this legacy unit with the SAU50X1000STC, a direct equivalent retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this SKU includes a piston magnet (-S), it originally worked with legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

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 SAU50X1000STC 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 SU50X1000STC Is Used
Long-Stroke Diversion
Pushes packages across a 1000mm conveyor lane using the 982 N push force at 0.5 MPa, guided externally to prevent rod bending.
TC-Mounted Actuation
Drives a pivoting assembly arm using the TC trunnion mount, allowing controlled angular movement during the 1000mm travel.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1000STC with the SAU50X1000STC
To replace the discontinued SU50X1000STC, order the SAU50X1000STC, confirming the 50mm bore, 1000mm stroke, M16x1.5 rod thread, 1/4" port, and TC mounting accessory are retained. If sizing down, a 40mm bore yields 628 N push at 0.5 MPa; if sizing up, a 63mm bore provides 1559 N. At 1000mm, this long stroke demands an external guide to prevent rod bending and side-load damage. The -S magnet means you must migrate from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Remember, the air cushion only decelerates the piston near stroke end; it does not hold the load on air loss. For secure load holding, install an external rod lock or pilot-operated check valve. If self-switching is needed, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1000STC
- ✓ 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 SU50X1000STC FAQ
Yes, the SU50X1000STC is discontinued. The direct replacement is the SAU50X1000STC. It shares the same 50mm bore, 1000mm stroke, 1/4" port, force, and SC-series TC mounting, so it fits the same application directly.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. Because this is an -S magnet model, the original legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
