This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X50-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X50-40 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 SUJ32X50-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-40 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 SAUJ32X50-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-40
The AirTAC SUJ32X50-40 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 10-50 mm extend window from the 50 mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. At 0.5 MPa it delivers 402 N push and 345 N pull via a 1/8" port. The exact drop-in replacement is the SAUJ32X50-40, sharing the same bore, stroke, force, port, and FA/LB mounting.
Because the stop screw sets the end position but is not a lock, loads drift without live air—use an external rod lock for holding. A computed buyer insight: the safe working load is roughly 241 N (60% of the 402 N push), translating to a 20 kg vertical lift with a 2:1 margin. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the SUJ's legacy CS1-B/DS1-B switches. This non-magnetic SKU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-40 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 SAUJ32X50-40 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 SUJ32X50-40 Is Used
Adjustable Stop Positioning
Ideal for test fixtures requiring precise extend endpoints, trimming the 50 mm stroke by up to 40 mm on-site without swapping cylinders.
Variable Depth Marking
Allows operators to dial in scribing or stamping depths on the fly using the external stop screw to set the exact end position.
Custom Ejector Travel
Perfect for ejection mechanisms needing variable reach, letting technicians shorten the extend stroke to accommodate different part sizes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-40 with the SAUJ32X50-40
To replace the discontinued SUJ32X50-40, order the SAUJ32X50-40 drop-in: it matches the 32 mm bore, 50 mm nominal stroke, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore yields 628 N push at 0.5 MPa, while dropping to lower pressure gives 563 N push at 0.7 MPa for this 32 mm bore. Choose the 40 mm adjust window if you need field stroke tuning between 10 and 50 mm; if a fixed 50 mm stroke is sufficient, a standard SAU cylinder suffices. For stroke lengths of 300 mm or greater, verify side-load limits. Note the sensor change: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAUJ.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-40
- ✓ 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 SUJ32X50-40 FAQ
Yes, the SUJ32X50-40 is discontinued. The exact drop-in replacement is the SAUJ32X50-40, which shares the same 32 mm bore, 50 mm stroke, 402 N force, 1/8" port, and FA/LB mounting.
The 32 mm bore delivers 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 provides a 40 mm adjust window, allowing the 50 mm extend stroke to be shortened to as little as 10 mm on-site.
