This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X100STC, 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 SU50X100STC
The AirTAC SU32~50 Standard Cylinder SU50X100STC 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 SAU50X100STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X100STC
The AirTAC SU50X100STC is a discontinued double-acting profile cylinder with a 50mm bore and 100mm stroke, delivering 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced it with the SAU50X100STC, a direct alternative retaining the exact bore, stroke, force, port size and SC-series TC mounting. The extruded aluminium profile is shorter than an equivalent ISO 15552 unit, and the SAU introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU means switching to current CMSG/DMSG/EMSG sensors. A plain cylinder drifts without live air, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X100STC 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 SAU50X100STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU50X100STC Is Used
Package Diverting
Pushes light to medium cartons off a main conveyor line using a safe 589N working load at 0.5MPa.
Pallet Stopper Gate
Acts as a compact 100mm stroke stop gate for pallets, reusing the existing SC-series TC mount bracket.
Component Clamping
Secures aluminium housings during machining, providing 825N pull force while saving space versus ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X100STC with the SAU50X100STC
To replace the SU50X100STC, order the SAU50X100STC and verify the 1/4" port, M16x1.5 rod thread and TC mounting interface. 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 self-switching, the SAUF variant integrates a 4M valve directly on the body. For loads needing 1374N at 0.7MPa, this 50mm bore fits, but if you require less force, drop to a 40mm bore (628N at 0.5MPa). The air cushion only decelerates the piston; it does not hold position, so add a pilot-operated check valve for vertical loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X100STC
- ✓ 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 SU50X100STC FAQ
Yes, the SU50X100STC is discontinued. The direct replacement is the SAU50X100STC, matching the 50mm bore, 100mm stroke, 1/4" port, 982N force and TC mounting.
It delivers 982N push and 825N pull at 0.5MPa, 1374N at 0.7MPa, and a 200kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
