This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X200SN, 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 SU50X200SN
The AirTAC SU32~50 Standard Cylinder SU50X200SN 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 SAU50X200SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X200SN
The AirTAC SU50X200SN is a discontinued double-acting profile-type cylinder with a 50mm bore and 200mm stroke. The direct replacement is the SAU50X200SN, matching the 1/4" port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The -N denotes NBR seals, operating from -20 to +70 C. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X200SN 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 SAU50X200SN 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 SU50X200SN Is Used
Package Diverting
Pushes medium-weight cartons at 200mm stroke on packaging lines, utilizing the 982 N push force at 0.5 MPa to actuate routing gates reliably.
Clamp Actuation
Secures workpieces during machining operations, providing consistent 825 N pull force while maintaining position via external check valves.
Vertical Lifting
Elevates components up to 50 kg in material handling setups, taking advantage of the compact profile body to save space in tight cells.
Replacing the Airtac SU32~50 Standard Cylinder SU50X200SN with the SAU50X200SN
To replace the SU50X200SN, order the SAU50X200SN direct equivalent, verifying the 1/4" port, M16x1.5 thread, and SC-series mounting (LB/FA/FB/CA/CB). If sizing alternatives, the adjacent 40mm bore yields 628 N push @0.5 MPa, while the 63mm bore provides 1559 N. At 200mm stroke, ensure adequate guide support to prevent rod bending under side loads. The built-in magnet means you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. Note that a standard cylinder drifts without live air; the cushion only decelerates near stroke end, so apply an external rod lock or pilot-operated check valve for load holding. If self-switching is desired, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X200SN
- ✓ 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 SU50X200SN FAQ
Yes, the SU50X200SN is discontinued. The direct replacement is the SAU50X200SN. It shares the same 50mm bore, 200mm stroke, 982 N output force at 0.5 MPa, 1/4" port, and SC-series mounting accessories. You simply order the SAU equivalent.
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 model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
