This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X220, 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 SU50X220
The AirTAC SU32~50 Standard Cylinder SU50X220 is a double-acting profile-type standard cylinder with a Ø50mm bore and 220mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X220, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X220
The AirTAC SU50X220 is a discontinued double-acting profile-type cylinder with a 50mm bore and 220mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa through a 1/4" port. AirTAC replaced this end-of-line unit with the SAU50X220 direct replacement, matching the exact bore, stroke, output force, port size and SC-series mounting accessories.
Because this specific SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade also switches to current CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option the SU line never had. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X220 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 SAU50X220 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 SU50X220 Is Used
Package Diverting
Actuates routing gates on 50mm belt conveyors, providing 982 N push at 0.5 MPa to redirect cartons weighing up to 50 kg safely.
Pallet Stopping
Functions as a compact pneumatic stop on roller conveyors, using its 220mm stroke to halt pallets smoothly via adjustable end cushions.
Clamp Actuation
Drives medium-duty clamping fixtures in machining cells, delivering 825 N pull force to secure aluminum housings during milling.
Replacing the Airtac SU32~50 Standard Cylinder SU50X220 with the SAU50X220
To replace this discontinued SU50X220, order the SAU50X220. Verify your 1/4" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB). Since this SKU has no -S magnet, it cannot hold a sensor. If you need position detection on the SAU, you must order the -S version and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing both ways: dropping to a 40mm bore gives 628 N push, while stepping up to a 63mm bore yields 1559 N. A plain cylinder drifts on air loss—the 21mm cushions only decelerate near stroke ends, so use an external rod lock for held loads. At 220mm stroke, rod bending is low, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU50X220
- ✓ 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 SU50X220 FAQ
Yes, the SU50X220 is discontinued. The direct replacement is the AirTAC SAU50X220. It shares the identical 50mm bore, 220mm stroke, 982 N force, 1/4" port, and SC-series mounting, so it drops right into the same application.
This double-acting cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushes 1374 N at 0.7 MPa, and reaches a 200 kgf maximum at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
