This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X160-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X160-75 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.

The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-75 is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X160-75, which matches its bore, stroke, force and mounting.
The AirTAC SUJ50X160-75 is a discontinued double-acting single-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 85-160 mm extend out of the 160 mm nominal maximum. This 50 mm bore version features a 1/4" port, a Ø20 mm rod, and delivers 982 N push and 825 N pull at 0.5 MPa. The stop sets the end position but is not a lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.
The exact drop-in replacement is the SAUJ50X160-75, retaining the same bore, stroke, force, port, and SC-series FA/LB mounting compatibility. This non-magnet SKU cannot take a sensor, but upgrading to the SAUJ allows using current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, the 982 N push at 0.5 MPa yields a safe working load of ~589 N (60% factor) and a vertical lift capacity of ~50 kg with a 2:1 margin.

The SAUJ50X160-75 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.
Dialing in the exact extend position on-site for pressing or crimping tasks where material thickness varies, utilizing the full 75 mm trim window.
Tuning the reach of a sorting diverter on a conveyor line to accommodate different package widths without changing the cylinder mount.
Quickly shortening the extend stroke on a packaging line pusher from 160 mm down to 85 mm during product size changeovers.
To replace the discontinued SUJ50X160-75, order the drop-in SAUJ50X160-75, which preserves the 75 mm adjust window, 1/4" port, and 160 mm maximum stroke. When sizing both ways, the neighboring 40 mm bore provides 628 N push at 0.5 MPa, while the 63 mm bore offers 1559 N push at 0.5 MPa. Choose the 75 mm adjust window when you need precise field tuning of the extend end position without swapping cylinders. Mounting is limited to AirTAC SC-series basic, FA, and LB styles. Because this specific SKU lacks a magnet, it cannot accept a sensor; moving to the SAUJ enables modern CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, carefully verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SUJ50X160-75 is discontinued. The exact drop-in replacement is the SAUJ50X160-75, which matches the 50 mm bore, 160 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors, whereas this non-magnet SUJ SKU cannot take a switch.
The 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and 1767 N push at 0.9 MPa, with a theoretical max of 200 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 85-160 mm. The stop sets end position only; it is not a load lock.
