This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X50-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X50-20S in place of this model. 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 SUJ Adjustable Cylinder SUJ32X50-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X50-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-20S
The AirTAC SUJ32X50-20S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable 30-50 mm extend out of the 50 mm nominal maximum. At 0.5 MPa it delivers 402 N push and 345 N pull force, peaking at 724 N push at 0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUJ32X50-20S, retaining the 1/8" port, M10x1.25 rod thread, and 21 mm adjustable cushions.
The SAUJ successor keeps the same compact profile body, bore, and SC-series FA/LB mounting, but upgrades position sensing from the legacy CS1-B/DS1-B switches used here to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 241 N (about 60% of the 0.5 MPa push), equating to a 20 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X50-20S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| -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 SUJ Adjustable Cylinder SUJ32X50-20S Is Used
Diverter Gate Positioning
Allows field tuning of the extend stroke by up to 20 mm to perfectly seat a diverter flap against varying product sizes without remachining the hard stop.
Package Pusher Stroke Trim
Ideal when a push-off stroke needs slight shortening on-site to accommodate a new carton width, using the external screw to set the exact 30-50 mm extend endpoint.
Light Sortation Arrestor
Provides adjustable end-position damping for a 32 mm bore stopper arm, letting technicians trim the 50 mm stroke to match changing conveyor lane widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-20S with the SAUJ32X50-20S
To replace the discontinued SUJ32X50-20S, order the SAUJ32X50-20S drop-in, which matches the 32 mm bore, 50 mm stroke, 1/8" port, and FA/LB mounting. The -20 adjust window lets you set the extend anywhere from 30 to 50 mm on-site, which beats fitting a fixed SAU cylinder plus an external stop block. If you need more force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa; if you can accept less, there is no smaller standard bore, so verify your load. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-20S
- ✓ 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 SUJ Adjustable Cylinder SUJ32X50-20S FAQ
Yes, the SUJ32X50-20S is discontinued. The exact drop-in replacement is the SAUJ32X50-20S, which shares the same 32 mm bore, 50 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You only need to upgrade the position sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
It provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The external stop screw window is 20 mm, meaning you can shorten the 50 mm nominal extend stroke down to 30 mm on-site. The stop sets end position and is not a load lock.
