This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X200S, 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 SU50X200S
The AirTAC SU32~50 Standard Cylinder SU50X200S is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X200S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X200S
The AirTAC SU50X200S is a discontinued double-acting profile-type cylinder with a 50mm bore and 200mm stroke. Built with an extruded aluminium barrel and adjustable air cushions at both ends, it delivers a push force of 982 N at 0.5 MPa (pull 825 N) via a 1/4" port. This compact profile body is shorter than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting accessories.
AirTAC replaced this end-of-life unit with the SAU50X200S, a direct replacement retaining the exact bore, stroke, output force, port size and mounting footprint. The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches, but the SAU upgrade uses the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X200S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU50X200S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×200 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X200S Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 200mm stroke to push cartons cleanly onto adjacent conveyor belts without stalling the flow.
Pallet Stopping
Functions as a pneumatic stop gate in low-profile roller conveyors, holding standard pallets securely until the downstream accumulation clears.
Clamp Actuation
Drives mid-force clamping fixtures for CNC machining, providing reliable 982 N hold at 0.5 MPa within a compact machinery footprint.
Replacing the Airtac SU32~50 Standard Cylinder SU50X200S with the SAU50X200S
To replace this discontinued SU50X200S, order the SAU50X200S. Confirm the 50mm bore, 200mm stroke, 1/4" port, M16x1.5 rod thread and your SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need integrated flow control, explore the SAUF valve-cylinder variant. For forces, the 50mm bore gives 982 N push at 0.5 MPa; if undersized, the 63mm bore yields 1559 N. At 200mm stroke, side-load risks are low, but always guide the load to prevent rod bending. Remember, a plain cylinder drifts on air loss—the cushion only decelerates; use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X200S
- ✓ 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 SU50X200S FAQ
Yes, the AirTAC SU50X200S is discontinued and end-of-life. The direct replacement is the SAU50X200S. It features the same 50mm bore, 200mm stroke, 982 N output force at 0.5 MPa, 1/4" port, and SC-series mounting compatibility. You can install it directly into your existing setup.
The 50mm bore provides 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 is the -S magnet version, it originally used legacy CS1-B/DS1-B switches. The SAU50X200S replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
