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

About the Airtac SUJ Adjustable Cylinder SUJ32X50-30
The AirTAC SUJ32X50-30 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 stroke from the 50 mm nominal maximum. The stop sets the end position but is not a load lock. This discontinued 32 mm bore unit delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and relies on adjustable 21 mm cushions to decelerate near stroke end.
The exact drop-in replacement is the SAUJ32X50-30, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), equating to a 20 kg vertical lift with a 2:1 margin. Without live air, the piston drifts; use an external rod lock for held loads. This SKU lacks a magnet and cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-30 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 SAUJ32X50-30 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 SUJ32X50-30 Is Used
Probe Positioning
Testing fixtures needing precise extend endpoints can field-trim the stroke by up to 30 mm to dial in exact probe contact depth.
Variable Stops
Light diverting gates on conveyors use the external stop screw to adjust the push distance for different package sizes on the fly.
Clamp Depth Tuning
Assembly stations clamping varied part heights rely on the adjustable stroke to set the exact 20-50 mm clamp reach without swapping cylinders.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-30 with the SAUJ32X50-30
To replace this discontinued unit, order the SAUJ32X50-30, which is a true drop-in match for bore, stroke, adjust window, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore offers 628 N push at 0.5 MPa, while smaller options step down in force. Choose the 30 mm adjust window if your fixture requires field tuning of the extend stroke within a 20-50 mm range. Because this SKU has no magnet, it cannot take a switch; if you need position sensing on the SAUJ, specify the -S option for CMSG/DMSG/EMSG sensor compatibility. For any stroke at or over 300 mm, verify your side-load limits to prevent guide wear. Remember the stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-30
- ✓ 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 SUJ32X50-30 FAQ
Yes, the SUJ32X50-30 is discontinued. The exact drop-in replacement is the SAUJ32X50-30, matching the 32 mm bore, 50 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting single-rod 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 an 82 kgf theoretical max at 1.0 MPa. The external stop screw provides a 30 mm adjust window, shortening the 50 mm nominal extend stroke down to 20 mm on-site. The stop sets end position and is not a load lock.
