This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-30 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 SUJ32X75-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-30 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 SAUJ32X75-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-30
The AirTAC SUJ32X75-30 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 45-75 mm extension from the 75 mm nominal maximum. This compact extruded-aluminum body is shorter than an ISO 15552 unit of the same bore, operating at 30-800 mm/s with a 1/8" port and M10x1.25 rod thread. The stop screw strictly sets the end position; it is not a load lock, so an external rod lock is required for held loads.
This SUJ model is discontinued and the exact drop-in replacement is the SAUJ32X75-30, retaining the 32 mm bore, 75 mm stroke, 1/8" port, and FA/LB mounting. At 0.5 MPa it delivers 402 N push and 345 N pull force, translating to a safe working load of roughly 241 N or a 20 kg vertical lift with a 2:1 margin. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ upgrade also shifts sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-30 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 SAUJ32X75-30 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 SUJ32X75-30 Is Used
Variable Pitch Forming
Bending or pressing operations where the extend stop must be dialed in precisely on-site for different material thicknesses without swapping cylinders.
Adjustable Diverter Arms
Routing packages of varying sizes on a line by trimming the 75 mm extend stroke down to 45 mm to set the exact deflection angle required.
Custom Depth Stops
Creating a mechanical end position for push-off mechanisms that handle mixed product depths, allowing rapid 30 mm stroke adjustments without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-30 with the SAUJ32X75-30
To replace the discontinued SUJ32X75-30, specify the SAUJ32X75-30 for an exact drop-in match on bore, stroke, 30 mm adjust window, and FA/LB mounts. When sizing both ways, the neighboring 40 mm bore offers higher force (628 N push @0.5 MPa) if you need more thrust, while staying at 32 mm keeps the 1/8" porting and compact profile. Choose the 30 mm adjust window if you need field stroke tuning; otherwise a fixed SAU is simpler. This non-magnetic SKU cannot take a switch, but if you order the -S version of the SAUJ, plan to upgrade to CMSG/DMSG/EMSG sensors as the legacy CS1-B/DS1-B are obsolete. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-30
- ✓ 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 SUJ32X75-30 FAQ
Yes, the SUJ32X75-30 is discontinued. The exact drop-in replacement is the SAUJ32X75-30, which matches the 32 mm bore, 75 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ family also supports current CMSG/DMSG/EMSG sensors and the SAUF built-in-valve variant.
It 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 shorten the extend stroke by up to 30 mm on-site, giving a usable extension range of 45-75 mm. The screw sets end position only and does not lock the load.
