This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-50S 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.
Airtac SUJ Adjustable Cylinder SUJ100X225-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-50S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X225-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-50S
The AirTAC SUJ100X225-50S is a double-acting, single-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 175-225 mm extend window from the 225 mm nominal maximum. The 100 mm bore generates 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" port, a 25 mm rod, and 29 mm adjustable cushions.
This SUJ unit is discontinued; the exact drop-in replacement is the SAUJ100X225-50S, sharing the same profile body, bore, force, and FA/LB mounting. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Note the stop screw sets end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade also moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-50S 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 SAUJ100X225-50S 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.

| ×225 | Stroke length in mm. |
| -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 SUJ100X225-50S Is Used
Variable Depth Pressing
Allows operators to dial in exact pressing depths on-site by trimming the extend stroke up to 50 mm without changing the cylinder body.
Adjustable Diverter Arms
Accommodates changing package sizes on a line by tweaking the extend stop position to alter the diverter reach dynamically.
Custom End-Stop Positioning
Sets precise mechanical end positions for varying pallet heights where a fixed stroke cylinder would require manual spacers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-50S with the SAUJ100X225-50S
To replace the discontinued SUJ100X225-50S, order the drop-in SAUJ100X225-50S, which preserves the 100 mm bore, 225 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N at 0.5 MPa (7068 N at 0.9 MPa). Choose the 50 mm adjust window if your application requires field-tuning the extend stroke down to 175 mm; otherwise, a fixed SAU cylinder is simpler. Because this unit has an -S magnet, you must switch from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-50S
- ✓ 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 SUJ100X225-50S FAQ
Yes, the SUJ100X225-50S is discontinued. The exact drop-in replacement is the SAUJ100X225-50S. It matches the 100 mm bore, 225 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. You will need to 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. The external stop screw provides a 50 mm adjust window, allowing the extend stroke to be shortened from the 225 mm maximum down to 175 mm on-site. The stop sets end position and is not a load lock.
