This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-50 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 SUJ32X75-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-50 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 SAUJ32X75-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-50
The AirTAC SUJ32X75-50 is a double-acting, single-rod adjustable-stroke profile cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 25-75 mm extension out of the 75 mm nominal maximum. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. The exact drop-in replacement is the SAUJ32X75-50, which matches the 32 mm bore, 1/8" port, and force.
At 0.5 MPa this 32 mm bore delivers 402 N push and 345 N pull force, peaking at 724 N push at 0.9 MPa. For sizing, a safe working load is roughly 241 N (about 60% of the 0.5 MPa push), translating to a 20 kg vertical lift with a 2:1 margin. The SAUJ upgrade transitions to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B, while retaining SC-series FA/LB mounting. Note this non-magnetic SKU lacks a piston magnet and cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-50 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 SAUJ32X75-50 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 SUJ32X75-50 Is Used
Variable Depth Drilling
A fixture requiring precise drill depth changes between batches uses the 50 mm adjust window to tune the extend stroke on-site without swapping cylinders.
Adjustable Diverter Arm
A sorting line alters the diverter stroke length on the fly to accommodate different package widths, utilizing the 25-75 mm usable extension range.
Format Change Pusher
Packaging equipment adjusts the pusher extension for varying carton sizes, relying on the external stop screw to set exact end positions quickly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-50 with the SAUJ32X75-50
To replace the discontinued SUJ32X75-50, order the drop-in SAUJ32X75-50, matching the 32 mm bore, 75 mm stroke, 50 mm adjust window, and 1/8" port. If re-sizing, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa, while dropping down reduces force. Choose the adjust window based on your maximum needed extension; here you can shorten the extend by up to 50 mm on-site. The stop screw sets the end position but is not a load lock—add an external rod lock for held loads. Because this specific SKU lacks a magnet, it cannot accept sensors; if sensing is required, select an -S SAUJ model using CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-50
- ✓ 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 SUJ32X75-50 FAQ
Yes, the SUJ32X75-50 is discontinued. The exact drop-in replacement is the SAUJ32X75-50, which matches the 32 mm bore, 75 mm stroke, 50 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.
This double-acting single-rod cylinder has a 32 mm bore and 1/8" port. Force is 402 N push / 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa (max 82 kgf at 1.0 MPa). The nominal 75 mm extend stroke can be shortened by up to 50 mm on-site, yielding a 25-75 mm usable extension.
