This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X100FB, 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 SU50X100FB
The AirTAC SU32~50 Standard Cylinder SU50X100FB 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 SAU50X100FB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X100FB
The AirTAC SU50X100FB is a discontinued double-acting profile-type cylinder with a 50mm bore and 100mm stroke. It delivers 982 N push force at 0.5 MPa and features a 1/4" port. AirTAC replaced this unit with the SAU50X100FB, a direct upgrade sharing the exact same body dimensions, force, port size, and SC-series FB mounting interface.
Because this SKU lacks a magnet, it cannot accept a position sensor. If sensing is required, the SAU replacement introduces a sensor groove compatible with modern CMSG/DMSG/EMSG switches, whereas the legacy SU used CS1-B/DS1-B. The SAU family also adds 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 SAU50X100FB 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 SAU50X100FB 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 SU50X100FB Is Used
Clamping Fixtures
Ideal for holding aluminum or composite parts during CNC machining, using the 982 N push force to secure components without deformation.
Package Diverting
Provides reliable actuation for 100mm stroke diverting gates on packaging lines, moving light-to-medium cartons efficiently.
Vertical Lift Stops
Suitable for lifting or stopping goods up to 50 kg on material handling systems, provided an external check valve prevents drift.
Replacing the Airtac SU32~50 Standard Cylinder SU50X100FB with the SAU50X100FB
To replace the SU50X100FB, order the SAU50X100FB. Confirm the 1/4" port, M16x1.5 rod thread, and the FB front-flange mounting accessory from the AirTAC SC-series. Since this specific SKU has no magnet (-S), it cannot support a magnetic switch; if you need end-position sensing on the new unit, specify the SAU with a magnet and upgrade to CMSG/DMSG/EMSG sensors. When sizing, note the 50mm bore yields 982 N push at 0.5 MPa; if you need less force, a 40mm bore provides 628 N, and if you need more, a 63mm bore offers 1559 N. Remember that a standard cylinder drifts without live air—the 21mm adjustable cushion only decelerates the piston near stroke end—so install an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X100FB
- ✓ 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 SU50X100FB FAQ
Yes, the AirTAC SU50X100FB is discontinued. The direct replacement is the SAU50X100FB. It matches the 50mm bore, 100mm stroke, 982 N force, 1/4" port, and SC-series FB mounting dimensions perfectly, so no mechanical redesign is required.
The 50mm bore generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept sensors; the SAU replacement supports CMSG/DMSG/EMSG switches if sensing is needed.
