This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X50-30SFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X50-30SFA 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 SUJ32X50-30SFA
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-30SFA 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 SAUJ32X50-30SFA, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-30SFA
The AirTAC SUJ32X50-30SFA is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 20-50 mm extend out of the 50 mm nominal maximum. The stop sets the end position but is not a load lock; a plain cylinder drifts on air loss and needs an external rod lock for holding. Bore 32 mm delivers 402 N push and 345 N pull at 0.5 MPa, with a 1/8" port and M10x1.25 rod thread.
This SUJ32X50-30SFA unit is discontinued and the drop-in replacement is the SAUJ32X50-30SFA, sharing the same bore, stroke, force, port and FA mounting interface. The SAUJ upgrade moves to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches on this -S magnet model. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push) and vertical lift is about 20 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-30SFA 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 SAUJ32X50-30SFA 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.

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 SUJ32X50-30SFA Is Used
Variable Depth Spotting
Adjusting the extend stop on-site to tune probe contact depth without swapping cylinders.
Variable Length Diverter
Trimming the extend stroke to deflect different package sizes accurately on a moving belt.
Adjustable Forming Stop
Setting precise end positions for carton forming or sealing heads of varying heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-30SFA with the SAUJ32X50-30SFA
To replace the discontinued SUJ32X50-30SFA, order the drop-in SAUJ32X50-30SFA, keeping the 32 mm bore, 50 mm nominal stroke, 30 mm adjust window, 1/8" port and FA mount. If you need more force, the neighbouring 40 mm bore gives 628 N push at 0.5 MPa; if you need less, there is no smaller standard SUJ bore so you must reduce pressure. Choose the 30 mm adjust window when you need field-tuning of the extend stroke between 20 and 50 mm. The SAUJ uses current CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-30SFA
- ✓ 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 SUJ32X50-30SFA FAQ
Yes, the SUJ32X50-30SFA is discontinued. The exact drop-in replacement is the SAUJ32X50-30SFA, which matches the 32 mm bore, 50 mm stroke, 30 mm adjust window, 1/8" port and FA mounting. You must upgrade the position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 20-50 mm from the 50 mm nominal maximum.
