This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X200STC, 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 SU40X200STC
The AirTAC SU32~50 Standard Cylinder SU40X200STC is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X200STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X200STC
The AirTAC SU40X200STC is a discontinued double-acting profile-type cylinder with a 40mm bore and 200mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 628 N push and 528 N pull at 0.5 MPa, operating at speeds of 30-800 mm/s through a 1/4" port. AirTAC replaced this legacy unit with the SAU40X200STC, a direct replacement retaining the exact body dimensions, force, and SC-series TC mounting interface.
Two key upgrades exist in the SAU transition: the legacy CS1-B/DS1-B switches used on this -S magnet model are replaced by current CMSG/DMSG/EMSG sensors, and the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X200STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X200STC 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 SU40X200STC Is Used
Package Diverting
Pushes lightweight cartons on a packaging line using the 628 N push force at 0.5 MPa, with the 200mm stroke clearing adjacent conveyor lanes.
Pallet Stopping
Acts as a pneumatic stop for inbound pallets, absorbing kinetic energy via the 21mm adjustable air cushions before the next workflow stage.
Component Clamping
Secures aluminum housings during CNC machining, providing a stable 528 N pull force while maintaining position via the TC mount.
Replacing the Airtac SU32~50 Standard Cylinder SU40X200STC with the SAU40X200STC
To replace this discontinued SU40X200STC, order the SAU40X200STC. Verify your 1/4" port, M12x1.25 rod thread, and TC mounting accessory are retained. Because this SKU includes the -S magnet, you must update your sensing setup: legacy CS1-B/DS1-B switches will not fit the SAU, requiring current CMSG/DMSG/EMSG sensors. If your application needs integrated flow control, consider the SAUF variant with its built-in valve. For force sizing, this 40mm bore yields 628 N push at 0.5 MPa; if you need less force, step down to a 32mm bore (402 N), or step up to a 50mm bore (982 N) for heavier loads. At 200mm stroke, side-load risks are low, but always guide the rod to prevent bending. Note that a standard cylinder drifts without live air—the cushion only decelerates near stroke end—so fit an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU40X200STC
- ✓ 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 SU40X200STC FAQ
Yes, the AirTAC SU40X200STC is discontinued. The direct replacement is the SAU40X200STC. It features the same 40mm bore, 200mm stroke, 1/4" port, and TC mounting compatibility. You will need to upgrade your sensors from the old CS1-B/DS1-B to the current CMSG/DMSG/EMSG family.
The 40mm bore utilizes a 1/4" port. It generates 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a theoretical maximum force of 128 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
