This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X200, 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 SU50X200
The AirTAC SU32~50 Standard Cylinder SU50X200 is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X200, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X200
The AirTAC SU50X200 is a discontinued double-acting profile-type cylinder with a 50mm bore and 200mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X200, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
When upgrading to the SAU50X200, the extruded aluminum body stays shorter than an ISO 15552 cylinder of the same bore. Note that this non-magnetic SKU cannot accept a sensor, and the SAU family now offers a SAUF variant with a built-in 4M solenoid valve that the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X200 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 SAU50X200 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 SU50X200 Is Used
Package Diverting
Pushes medium-weight cartons off a main conveyor line using a 982N push force at 0.5MPa, with the 200mm stroke clearing the belt width.
Pallet Stopping
Acts as a pneumatic stop for incoming pallets on a gravity roller track, safely absorbing the impact using the 21mm adjustable air cushions.
Clamp Actuation
Drives a secondary clamping arm on an assembly fixture, providing 825N pull force to hold a workpiece securely during machining.
Replacing the Airtac SU32~50 Standard Cylinder SU50X200 with the SAU50X200
To replace this SU50X200, order the SAU50X200 ensuring your 1/4" port, M16x1.5 rod thread, and SC-series mounting accessories are retained. Because this specific SKU lacks a magnet, it cannot accept a sensor; if you need position detection on the replacement, you must specify an SAU50X200S and migrate to the current CMSG/DMSG/EMSG switch family (the legacy CS1-B/DS1-B switches are obsolete). Sizing both ways: if you need more force, the 63mm bore yields 1559N push at 0.5MPa; if you need less, the 40mm bore yields 628N. A plain cylinder does not hold load on air loss—the 21mm adjustable cushion only decelerates near stroke end—so use an external rod lock or pilot-operated check valve for vertical holding. At 200mm stroke, side-load and rod-bending are minimal, but always guide the load to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X200
- ✓ 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 SU50X200 FAQ
Yes, the SU50X200 is discontinued. The direct replacement is the AirTAC SAU50X200. It shares the identical 50mm bore, 200mm stroke, 982N force, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
This 50mm bore cylinder provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; if detection is needed, order the SAU50X200S replacement which uses current CMSG/DMSG/EMSG switches.
