This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-50S 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 SUJ32X75-50S 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 SAUJ32X75-50S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X75-50S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. With a nominal 75 mm stroke, the usable extend range is 25-75 mm. The stop screw sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss. This 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, scaling to 563 N at 0.7 MPa and 724 N at 0.9 MPa.
This discontinued model is fully replaced by the SAUJ32X75-50S, which preserves the 1/8" port, M10x1.25 rod thread, and 21 mm cushions. The drop-in SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. For sizing, the 402 N @0.5 MPa push yields a safe working load of ~241 N (60% factor) and a ~20 kg vertical lift capacity with a 2:1 margin. The compact extruded aluminum barrel is shorter than standard cylinders of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-50S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ32X75-50S 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.
Trimming the 75 mm extend stroke down to 25 mm on-site to set precise boring depths in soft materials without swapping the cylinder.
Tuning the extend end position to handle varying package sizes on a 1/8" port pneumatic conveyor line without mechanical spacers.
Field-adjusting the divert stroke by up to 50 mm to accommodate changing product profiles in compact sorting stations.
To replace the discontinued SUJ32X75-50S, order the drop-in SAUJ32X75-50S, which matches the 32 mm bore, 75 mm nominal stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. If re-engineering, the neighboring 40 mm bore provides 628 N push at 0.5 MPa, while dropping to a smaller bore reduces force. Choose the 50 mm adjust window if you need to trim the extend stroke on-site from 75 mm down to 25 mm. Note that the SAUJ uses CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SUJ32X75-50S is discontinued. The exact drop-in replacement is the SAUJ32X75-50S, which matches the 32 mm bore, 75 mm stroke, 50 mm adjust window, and 1/8" port. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
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. The external stop screw provides a 50 mm adjust window, allowing the 75 mm extend stroke to be shortened to 25 mm on-site. The stop sets end position but is not a load lock.
