This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X175-100S, 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 MALJ25X175-100-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 75 to 175 mm. This model is discontinued — the direct replacement is the MBLJ25X175-100-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S
The AirTAC MALJ25X175-100-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. The -100 adjust code lets you trim the rear travel stop by up to 100 mm, creating a usable end-position window of 75-175 mm without external stops.
The direct replacement is the MBLJ25X175-100-S, matching the 25 mm bore, 175 mm stroke, G1/8 port, and FA/LB mounting. This MALJ uses a fixed rubber bumper, not an adjustable cushion, and the adjuster is a travel stop that does not hold load without live air. Its threaded covers and CS1-M/DS1-M magnet switches are upgraded in the MBLJ to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X175-100-S |
| Bore size | Ø25 mm |
| Stroke | 175 mm |
| Adjustable window | 75 – 175 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
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 MBLJ25X175-100-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 MBLJ25X175-100-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S Is Used
Carton Flap Folding Arm
Adjust the rear stopper to time the folding arm stroke on a case erector, accommodating varying carton widths while the 206 N pull force reliably retracts the linkage.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S with MBLJ25X175-100-S
To replace the MALJ25X175-100-S, order the direct replacement MBLJ25X175-100-S. Confirm the 25 mm bore, 175 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet on this MALJ uses CS1-M/DS1-M switches; the MBLJ upgrade requires CMSG/DMSG/EMSG sensors. The adjuster is a stop, not a lock.
Because the 175 mm stroke is long for a mini cylinder, minimize side loads to prevent rod bending. The fixed rubber bumper softens impact but offers no air cushioning.
Upgrade checklist
- ✓ Order the MBLJ25X175-100-S (same bore/stroke/adjust)
- ✓ Same 75–175 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 MBLJ25X175-100-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-100-S FAQ
Yes, the MALJ25X175-100-S is discontinued. The direct replacement is the MBLJ25X175-100-S, which matches the bore, stroke, 100 mm adjust code, force, and port. You will need to update your sensor selection from the old CS1-M/DS1-M switches to the new CMSG/DMSG/EMSG family.
The -100 adjust code allows trimming the rear stopper by up to 100 mm, creating a usable stroke window of 75-175 mm. The adjuster is a travel stop, not a lock, and the cylinder uses a fixed rubber bumper.
