This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-30S 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 SUJ32X75-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X75-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-30S
The AirTAC SUJ32X75-30S 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 45-75 mm extend out of the 75 mm nominal maximum. The 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa (563 N push at 0.7 MPa), operating at 30-800 mm/s through a 1/8" port. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ32X75-30S model is discontinued; the exact drop-in replacement is the SAUJ32X75-30S, retaining the same bore, stroke, adjust window, force, port, and FA/LB mounting. The upgrade path moves legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), translating to a 20 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-30S 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 SAUJ32X75-30S 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 SUJ32X75-30S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 30 mm allows a single 32 mm bore cylinder to push parts of varying widths into a machining station without swapping the entire actuator.
Adjustable Diverting Gate
Trimming the extend stroke from 75 mm down to 45 mm accommodates different package sizes on a conveyor line, letting operators readjust the stop screw as product formats change.
Variable Depth Stopping
Using the external stop screw to set precise end positions between 45 and 75 mm provides a field-adjustable hard stop for parts feeding into a packaging cell.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-30S with the SAUJ32X75-30S
To replace the discontinued SUJ32X75-30S, order the drop-in SAUJ32X75-30S, which preserves the 32 mm bore, 75 mm nominal stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa if more force is needed, while the 32 mm bore offers 402 N push. Choose the 30 mm adjust window if your fixture needs field tuning between 45 and 75 mm; the stop screw sets the end position but does not lock the load. Because this unit has the -S magnet, swap the legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. Although this stroke is under 300 mm, for longer applications ensure side-load limits are respected.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-30S
- ✓ 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 SUJ32X75-30S FAQ
Yes, the SUJ32X75-30S is discontinued. The exact drop-in replacement is the SAUJ32X75-30S, which matches the 32 mm bore, 75 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the switches from legacy CS1-B/DS1-B to 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, 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 30 mm, allowing you to trim the 75 mm nominal extend stroke down to a 45 mm minimum on-site. The stop sets end position only and is not a load lock.
