This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X200-75FA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X200-75FA 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 SUJ63X200-75FA
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-75FA is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ63X200-75FA, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-75FA
The AirTAC SUJ63X200-75FA is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 125-200 mm extension from the 200 mm nominal maximum. This discontinued unit delivers 1559 N push and 1402 N pull at 0.5 MPa, scaling to 2805 N at 0.9 MPa. The 63 mm bore uses a 3/8" port, a Ø20 mm rod, and 21 mm adjustable cushions. Because this SKU lacks a magnet, it cannot accept a magnetic switch for position sensing.
As the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ63X200-75FA, which preserves the bore, stroke, force, port, and FA mounting interface. The SAUJ upgrade transitions to current CMSG/DMSG/EMSG sensors, departing from the legacy CS1-B/DS1-B switches used here. For sizing, a safe working load is roughly 935 N (about 60% of the 0.5 MPa push), translating to a 79 kg vertical lift with a 2:1 margin. Remember that the stop screw sets the end position but is not a load lock; the piston drifts on air loss, so use an external rod lock for held loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUJ63X200-75FA 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 SUJ63X200-75FA Is Used
Variable Pitch Indexing
Dialing the extend stroke on-site by up to 75 mm allows a single actuator to push parts into fixtures at varying distances without swapping the cylinder.
Adjustable Transfer Pusher
Trimming the 200 mm extension lets operators fine-tune the pusher end position to match cartons of differing widths on the line.
Custom Length Diverter
The external stop screw provides a hard, field-adjustable end position for sorting items, avoiding the deflection of relying solely on internal cushions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-75FA with the SAUJ63X200-75FA
To replace the discontinued SUJ63X200-75FA, order the SAUJ63X200-75FA drop-in, matching the 63 mm bore, 200 mm stroke, 75 mm adjust window, and 3/8" port. If migrating to the SAUJ family, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. When sizing both ways, the neighboring 50 mm bore provides 982 N push at 0.5 MPa, while the 80 mm bore offers 2513 N; this 63 mm unit provides 1559 N. Choose the 75 mm adjust window if your fixture needs on-site extend tuning between 125 and 200 mm, which often beats installing a fixed-stroke cylinder with an external stop. The FA mount is an SC-series accessory. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. This non-magnetic SKU cannot take a switch; if sensing is needed, select an -S model.

Airtac SUJ Adjustable Cylinder SUJ63X200-75FA FAQ
Yes, the SUJ63X200-75FA is discontinued. The exact drop-in replacement is the SAUJ63X200-75FA, which matches the 63 mm bore, 200 mm stroke, 75 mm adjust window, 3/8" port, and FA mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 2805 N at 0.9 MPa. The external stop screw window is 75 mm, allowing you to shorten the 200 mm nominal extend stroke down to 125 mm on-site. The stop sets end position but is not a load lock.
