This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X160-75S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 85 to 160 mm. This model is discontinued — the direct replacement is the MBLJ25X160-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S
The AirTAC MALJ25X160-75-S is a discontinued, double-acting, double-rod mini cylinder with a 25mm bore and a 160mm stroke. It features a rear travel stopper that lets you trim up to 75mm, creating a usable end-position window of 85-160mm without external stops.
The MBLJ25X160-75-S is a direct upgrade retaining the same G1/8 port, M10x1.25 rod thread, and 50kgf max force. Two structural upgrades exist: the MALJ uses threaded covers while the MBLJ uses a riveted rolling-packed body, and the MALJ -S magnet works with older CS1-M/DS1-M switches while the MBLJ requires CMSG/DMSG/EMSG sensors. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ25X160-75-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ25X160-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S Is Used
Carton Flap Folder
Adjust the rear stopper to tune the folding arm reach on a packaging line, using the 206N pull force to tuck flaps without needing to swap the cylinder for a shorter stroke unit.
Pneumatic Press Pin Insertion
Set a precise 120mm down-stroke for pressing connector pins into housings, using the fixed rubber bumper to soften the end impact and the rear screw to dial in the exact insert depth.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S with MBLJ25X160-75-S
To replace the MALJ25X160-75-S, order the exact direct replacement MBLJ25X160-75-S. Confirm the 25mm bore, 160mm stroke, 75mm adjust code, PT G1/8 port, and M10x1.25 rod-end thread. Mounting remains Basic, FA, or LB only, as there is no back-cover or SDB option. If your machine uses the -S magnet, note that you must upgrade your switches from the old CS1-M/DS1-M to the CMSG/DMSG/EMSG family. The rear adjuster is a travel stop, not a lock; it will not hold a load without live air.
At a 160mm stroke, the rod is susceptible to bending if side loads are applied; ensure strict axial alignment to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ25X160-75-S (same bore/stroke/adjust)
- ✓ Same 85–160 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ25X160-75-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-75-S FAQ
Yes, the MALJ25X160-75-S is discontinued. The direct replacement is the MBLJ25X160-75-S, which matches the 25mm bore, 160mm stroke, 75mm adjust code, G1/8 port, and 50kgf max force. You must upgrade your sensors, as the MALJ -S magnet uses CS1-M/DS1-M switches while the MBLJ uses CMSG/DMSG/EMSG.
The 75mm rear adjuster creates a usable stroke window from 85mm to 160mm. The adjuster is a travel stop, not a lock; it will not hold a load without live air.
