This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X200-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X200-100 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 SUJ50X200-100 is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X200-100, which matches its bore, stroke, force and mounting.
The AirTAC SUJ50X200-100 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 100-200 mm stroke. This discontinued unit delivers 982 N push and 825 N pull at 0.5 MPa, peaking at 1767 N push at 0.9 MPa. It features a 1/4" port, a Ø20 mm rod, and 21 mm adjustable cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The exact drop-in replacement is the SAUJ50X200-100, retaining the same bore, stroke, force, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches (this legacy SKU used CS1-B/DS1-B). Because this specific model lacks a magnet, it cannot take a magnetic switch. For sizing, the 982 N @0.5 MPa push yields a safe working load of ~589 N, lifting ~50 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ50X200-100 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.
Allows on-site extend stroke tuning from 100 to 200 mm to alter part pitch without swapping cylinders.
Provides field-adjustable push distance to accommodate changing package widths on a sorting line.
Sets precise carton end positions on the fly, trimming the extend stroke by up to 100 mm for varied box lengths.
To replace the discontinued SUJ50X200-100, specify the drop-in SAUJ50X200-100, matching the 50 mm bore, 200 mm nominal stroke, and 100 mm adjust window. If migrating, note the SAUJ uses CMSG/DMSG/EMSG sensors whereas the SUJ used CS1-B/DS1-B; this non-magnetic SKU cannot accept a switch anyway. Size both ways using 0.5 MPa force: the neighbouring 40 mm bore gives 628 N push, while the 63 mm bore yields 1559 N. Choose the 100 mm adjust window when you need field-tuning over a wide 100-200 mm range. Mounting uses FA or LB brackets. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The external stop sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
Yes, the SUJ50X200-100 is discontinued. The exact drop-in replacement is the SAUJ50X200-100, offering the same 50 mm bore, 200 mm stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting single-rod cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushing 1374 N at 0.7 MPa and 1767 N at 0.9 MPa. The external stop screw trims the extend stroke by up to 100 mm on-site, giving a usable 100-200 mm stroke. The stop sets end position but is not a load lock.
