This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X250-75S, 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 MALJ25X250-75S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X250-75S 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 175 to 250 mm. This model is discontinued — the direct replacement is the MBLJ25X250-75S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-75S
The AirTAC MALJ25X250-75S is a discontinued double-acting double-rod mini cylinder with a 75 mm rear adjuster. This yields a usable stroke window of 175-250 mm. The direct replacement is the MBLJ25X250-75S, matching bore, stroke, port, and force.
The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. This MALJ has threaded covers and a fixed rubber bumper, while the MBLJ upgrade uses a riveted rolling-packed body. The -S magnet on this SKU works with CS1-M / DS1-M switches; the MBLJ replacement uses CMSG / DMSG / EMSG sensors.

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 MBLJ25X250-75S 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 MBLJ25X250-75S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-75S Is Used
Wire harness tape wrap
Adjust the rear stop to fine-tune the end position of a wire tape applicator head, ensuring consistent wrapping depth without re-machining the 250 mm travel carriage.
Aluminum extrusion end-facing
Trim the cylinder stroke down to 175 mm to face aluminum extrusion ends accurately, relying on the fixed rubber bumper to soften the impact at the end of travel.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-75S with MBLJ25X250-75S
Replace this MALJ25X250-75S with the exact direct replacement MBLJ25X250-75S. Confirm the 25 mm bore, 250 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The adjuster sets the end position but does not hold load; add an external lock for suspended loads. The -S magnet changes sensor families from CS1-M / DS1-M to CMSG / DMSG / EMSG.
At 250 mm stroke, the 10 mm rod is susceptible to side-load bending; guide the load to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ25X250-75S (same bore/stroke/adjust)
- ✓ Same 175–250 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 MBLJ25X250-75S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-75S FAQ
Yes, the MALJ25X250-75S is discontinued. The direct replacement is the MBLJ25X250-75S, matching the 25 mm bore, 250 mm stroke, 75 mm adjust code, G1/8 port, and 50 kgf max force. The MBLJ upgrades the threaded covers to a riveted rolling-packed body and changes the -S magnet sensor compatibility from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 75 mm adjust code lets you trim the rear position, creating a usable stroke window from 175 mm to 250 mm. The adjuster is a travel stop, not a lock.
