This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X200-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X200-20S 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 SUJ100X200-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X200-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X200-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X200-20S
The AirTAC SUJ100X200-20S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable forward travel of 180-200 mm. This discontinued 100 mm bore model delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable cushions. The exact drop-in replacement is the SAUJ100X200-20S, matching the bore, stroke, force, and mounting.
For sizing, a safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push figure), translating to a vertical lift capacity near 200 kg with a 2:1 margin. The stop screw sets the end position but is not a lock; without live air the piston drifts, so use an external rod lock for held loads. Beyond the sensor upgrade from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, the compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. The SAUJ also offers an SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X200-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X200-20S 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.

| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X200-20S Is Used
Press Fit Tuning
Allows operators to dial in the exact 180-200 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Provides adjustable reach for diverting different package sizes on a line, trimming the stroke by up to 20 mm as needed.
Adjustable Height Stops
Sets precise mechanical end positions for pallet lifting or lowering stages where the exact lower bound varies by pallet type.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X200-20S with the SAUJ100X200-20S
To replace the discontinued SUJ100X200-20S, order the drop-in SAUJ100X200-20S, which retains the exact 100 mm bore, 200 mm stroke, 20 mm adjust window, 1/2 inch port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at 0.5 MPa and 7068 N at 0.9 MPa. Choose the 20 mm adjust window if you need precise field tuning of the extend stroke; the external stop screw is ideal when a fixed SAU plus external stop is too bulky. Because this is an -S model, you must upgrade your position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X200-20S
- ✓ 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 SUJ100X200-20S FAQ
Yes, the SUJ100X200-20S is discontinued. The exact drop-in replacement is the SAUJ100X200-20S, which matches the 100 mm bore, 200 mm stroke, 20 mm adjust window, 1/2 inch port, and FA/LB mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw window is 20 mm, allowing you to shorten the 200 mm extend stroke down to 180 mm on-site. The stop sets end position but is not a load lock.
