This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X100S, 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 SU50X100S
The AirTAC SU32~50 Standard Cylinder SU50X100S is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X100S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X100S
The AirTAC SU50X100S is a discontinued double-acting profile-type cylinder with a 50mm bore and 100mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X100S, a direct upgrade retaining the exact body, force, and SC-series mounting.
The SAU50X100S keeps the extruded aluminum profile—shorter than a same-bore ISO 15552 unit—but updates the magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. It also adds the SAUF built-in 4M valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X100S 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 SAU50X100S 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 SU50X100S Is Used
Component Clamping
Secures workpieces during machining with 982 N of push force at 0.5 MPa, providing stable holding without excessive bulk.
Package Diverting
Actuates routing gates on packaging lines; the compact profile body and 100mm stroke fit neatly into tight conveyor frames.
Replacing the Airtac SU32~50 Standard Cylinder SU50X100S with the SAU50X100S
To replace the SU50X100S, order the SAU50X100S, confirming the 1/4" port, M16x1.5 rod thread, and SC-series mounts (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: a 40mm bore gives 628 N push, while a 63mm bore yields 1559 N. A plain cylinder drifts on air loss—the 21mm cushions only decelerate; for load holding use an external rod lock or pilot-operated check valve. The SAUF valve-integrated variant can simplify cycling. At 100mm stroke, rod bending is minimal, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU50X100S
- ✓ 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 SU50X100S FAQ
Yes, the SU50X100S is discontinued. The direct replacement is the AirTAC SAU50X100S. It shares the same 50mm bore, 100mm stroke, 982 N output force, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5 MPa it provides 982 N push and 825 N pull; 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 SU used CS1-B/DS1-B switches, but the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
