This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X250-50, 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 MALJ25X250-50
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 200 to 250 mm. This model is discontinued — the direct replacement is the MBLJ25X250-50.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50
The AirTAC MALJ25X250-50 adjustable-stroke mini cylinder is discontinued, replaced by the direct replacement MBLJ25X250-50. This double-acting double-rod unit has a 25mm bore and a 250mm stroke, with a rear screw letting you trim the end position by up to 50mm. You get a usable 200-250mm stroke window without swapping hardware.
The MBLJ25X250-50 keeps the same G1/8 port, M10x1.25 rod thread, and 50kgf max force. This SKU lacks a magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it cannot hold a load without live air. The fixed rubber bumper softens end impact, but is not an adjustable cushion. Upgrading to the MBLJ moves you from threaded covers to a riveted rolling-packed body.

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 MBLJ25X250-50 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 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 MBLJ25X250-50 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50 Is Used
Carton Flap Folder
Fine-tune the folding arm on a packaging line to match varying box heights, relying on the fixed rubber bumper to absorb the 250mm stroke end impact.
Pneumatic Arbor Press
Adjust the 50mm stopper to control pressing depth for bearing inserts, preventing over-travel while the 206N pull retracts the tool safely.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50 with MBLJ25X250-50
Replace this MALJ25X250-50 with the exact direct replacement MBLJ25X250-50. Confirm your 25mm bore, 250mm stroke, 50mm adjust code, G1/8 PT port, and FA or LB mounting (no back cover or SDB allowed). This SKU has no magnet, so you cannot mount a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need sensing. Remember the rear adjuster is a stop, not a lock. At 250mm stroke, watch rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ25X250-50 (same bore/stroke/adjust)
- ✓ Same 200–250 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 MBLJ25X250-50 instead of this discontinued model.
