This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X180S, 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 SU50X180S
The AirTAC SU32~50 Standard Cylinder SU50X180S is a double-acting profile-type standard cylinder with a Ø50mm bore and 180mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X180S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X180S
The AirTAC SU50X180S is a discontinued double-acting profile-type cylinder featuring a 50mm bore, 180mm stroke, and an integrated piston magnet. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X180S, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade introduces modern CMSG/DMSG/EMSG sensors to replace this model's older CS1-B/DS1-B switches, and adds an optional SAUF built-in 4M valve variant. Note that a plain cylinder drifts without live air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X180S 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 SAU50X180S 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 SU50X180S Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 180mm stroke to push cartons cleanly onto adjacent conveyors.
Pallet Stopper Gate
Functions as a pneumatic stop gate for pallets, raising and lowering to control workflow on roller conveyors.
Clamp Actuation
Provides reliable clamping force for light machining fixtures, securing components during drilling or tapping.
Replacing the Airtac SU32~50 Standard Cylinder SU50X180S with the SAU50X180S
To replace the SU50X180S, order the SAU50X180S, confirming the 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU includes the -S magnet, you must upgrade your switches from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG family. For sizing both ways: dropping to a 40mm bore yields 628N push at 0.5MPa, while stepping up to a 63mm bore provides 1559N. At 180mm stroke, side-load risks are low, but always guide the load to prevent rod bending. If you need self-switching, the SAUF variant integrates a 4M solenoid valve. Remember that standard cushions only decelerate; install a pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU50X180S
- ✓ 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 SU50X180S FAQ
Yes, the SU50X180S is discontinued. The direct replacement is the AirTAC SAU50X180S. It matches the 50mm bore, 180mm stroke, 1/4" port, and SC-series mounting accessories. You simply order the SAU equivalent.
The cylinder provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical maximum of 200kgf at 1.0MPa. Because your SU50X180S has a magnet, note that the SAU replacement requires upgrading from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family.
