This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X750SN, 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 SU50X750SN
The AirTAC SU32~50 Standard Cylinder SU50X750SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 750mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X750SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X750SN
The AirTAC SU50X750SN is a discontinued double-acting profile cylinder with a 50mm bore and 750mm stroke. Delivering 982 N push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU50X750SN, matching the bore, stroke, 1/4" port, and SC-series mounting. The NBR seal supports -20 to +70 C.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, and adds a SAUF built-in-valve option the SU line lacked. The 1/4" port and M16x1.5 rod thread are unchanged.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X750SN 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 SAU50X750SN 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 SU50X750SN Is Used
Long-Stroke Diversion
Pushes packages across a 750mm conveyor lane using a 982 N working force at 0.5 MPa, guided externally to prevent rod bending.
Material Ejection
Ejects molded parts from a press using the 1767 N thrust at 0.9 MPa, relying on the 21mm adjustable cushions to decelerate at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU50X750SN with the SAU50X750SN
To replace this SU50X750SN, order the SAU50X750SN. Verify the 50mm bore, 750mm stroke, 1/4" port, and PT thread. Because of the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. The -N NBR seal is retained. Sizing neighbors: a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. For the 750mm stroke, use an external guide to prevent rod bending and side loads. The cylinder does not hold load without live air; use a pilot-operated check valve or rod lock for holding. If self-switching is needed, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X750SN
- ✓ 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 SU50X750SN FAQ
Yes, the SU50X750SN is discontinued. The direct replacement is the SAU50X750SN. It shares the same 50mm bore, 750mm stroke, 1/4" port, output force, and SC-series mounting. You simply order the SAU equivalent.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf max at 1.0 MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors. The air cushion only decelerates; it does not hold the load.
