This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X175-50, 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 MALJ25X175-50

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-50
The AirTAC MALJ25X175-50 is a discontinued adjustable-stroke mini cylinder. The direct replacement is the MBLJ25X175-50, matching the 25mm bore, 175mm stroke, G1/8 port and 50mm adjuster code. This double-acting double-rod unit trims up to 50mm at the rear, creating a usable stroke window of 125-175mm.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. Impact absorption relies entirely on that rubber bumper, as there is no adjustable air cushion.

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 MBLJ25X175-50 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 MBLJ25X175-50 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-50 Is Used
PCB Depaneling Saw Stop
Dial the exact 145mm cut depth on a circular depaneling saw to sever router arrays without stressing surface-mount components.
Sheet Metal Forming Backstop
Set a precise 130mm retracted home position for a small press brake die, using the fixed rubber bumper to absorb the 206N pull impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-50 with MBLJ25X175-50
To replace the MALJ25X175-50, order the MBLJ25X175-50. Confirm the 25mm bore, 175mm stroke, 50mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back cover or SDB option). Because this SKU has no magnet, you lose any sensor capability; if you need switches, step up to an MBLJ25X175-50S which uses the newer CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
At 175mm stroke, minimize side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ25X175-50 (same bore/stroke/adjust)
- ✓ Same 125–175 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 MBLJ25X175-50 instead of this discontinued model.
