This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X50-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X50-50S 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 SUJ32X50-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-50S 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 SAUJ32X50-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-50S
The AirTAC SUJ32X50-50S is a double-acting single-rod profile cylinder with a 50mm adjustable stroke window, letting you trim the extend stroke by up to 50mm on-site. This discontinued 32mm bore model delivers 402N push and 345N pull at 0.5MPa, features a 1/8" port, and uses an external stop screw to set the end position. The drop-in replacement is the SAUJ32X50-50S, matching the bore, stroke, force, and SC-series FA/LB mounting.
For sizing, the safe working load is roughly 241N (60% of the 402N push figure), yielding a 20kg vertical lift capacity with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade keeps the compact profile body but switches sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-50S 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 SAUJ32X50-50S 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.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 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 SUJ32X50-50S Is Used
Variable Depth Drilling
Allows operators to tune the extend stroke on-site for material thickness variations without swapping cylinders.
Adjustable Pusher Diverter
Provides field stroke tuning to alter the push distance for different package sizes on a packaging line.
Variable Height Stops
Sets precise mechanical end positions for varying product heights where a fixed stroke is too limiting.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-50S with the SAUJ32X50-50S
To replace this discontinued SUJ32X50-50S, order the drop-in SAUJ32X50-50S, which preserves the 50mm adjust window, 1/8" port, and FA/LB mounts. When sizing both ways, the neighboring 40mm bore provides 628N push at 0.5MPa, while this 32mm bore offers 402N. Select the adjust window based on your maximum needed extend trim. Because this model has the -S magnet, note that the SAUJ requires current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 50mm stroke, side-load is minimal, but always guide the rod for rigid loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-50S
- ✓ 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 SUJ32X50-50S FAQ
Yes, the SUJ32X50-50S is discontinued. The exact drop-in replacement is the SAUJ32X50-50S, which matches the 32mm bore, 50mm stroke, 50mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a max of 82kgf at 1.0MPa. The external stop screw allows you to trim the extend stroke by up to 50mm on-site, setting the end position but not acting as a load lock.
