This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X160CB, 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 SU50X160CB
The AirTAC SU32~50 Standard Cylinder SU50X160CB is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X160CB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X160CB
The AirTAC SU50X160CB is a discontinued double-acting profile-type cylinder with a 50mm bore and 160mm 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 SAU50X160CB, a direct upgrade retaining the exact body dimensions, M16x1.5 rod thread, 21 mm cushions and SC-series CB mounting interface.
Because this SKU lacks a magnet, it cannot accept a piston switch. The SAU successor additionally supports modern CMSG/DMSG/EMSG sensors on its -S variants and introduces the SAUF built-in 4M solenoid valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X160CB 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 SAU50X160CB 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 SU50X160CB Is Used
Mid-Tonnage Clamping
Secures workpieces in CNC machining fixtures using the 982 N push force at 0.5 MPa, ensuring rigid holding without deflecting the component.
Pneumatic Pressing
Performs light-duty bearing insertion or stamping tasks where the 825 N pull force safely retracts the tooling after the press cycle.
Replacing the Airtac SU32~50 Standard Cylinder SU50X160CB with the SAU50X160CB
To replace the SU50X160CB, order the SAU50X160CB. Confirm the 50mm bore, 160mm stroke, 1/4" port (default PT), M16x1.5 rod thread and CB rear-hinge mount. This non-magnetic SKU cannot hold a sensor; if you need position detection on the SAU, add the -S suffix and migrate from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG switches. For higher loads, the 63mm bore provides 1559 N push at 0.5 MPa; for tighter spaces, the 40mm bore offers 628 N. Note that standard cushions only decelerate the piston near stroke end—a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads. At 160mm stroke, side-load and rod-bending forces are minimal, but always guide the load rigidly.
Replacement checklist
- ✓ Same bore / stroke → SAU50X160CB
- ✓ 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 SU50X160CB FAQ
Yes, the AirTAC SU50X160CB is discontinued. The direct replacement is the SAU50X160CB. It shares the identical 50mm bore, 160mm stroke, 1/4" port, 982 N output force and SC-series CB mounting, so it bolts directly into the same application.
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 specific SKU lacks a magnet, it cannot accept a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
