This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X350-75-S, 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 MALJ20 Adjustable Mini Cylinder MALJ20X350-75-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-75-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 275 to 350 mm. This model is discontinued — the direct replacement is the MBLJ20X350-75-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-75-S
The AirTAC MALJ20X350-75-S is a discontinued double-acting, double-rod mini cylinder. As an adjustable-stroke unit, its rear stopper screw trims up to 75 mm, giving a usable extension window of 275-350 mm. Note that this 350 mm stroke exceeds the 300 mm standard for bore 20, making it a non-standard, made-to-order length. The direct replacement is the MBLJ20X350-75-S, matching the bore, force, G1/8 port, and mounting.
It features a fixed rubber bumper and a heterogeneous grease-retaining seal. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ brings a riveted rolling-packed body instead of threaded covers, and the -S magnet switches from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG family.

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 MBLJ20X350-75-S carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X350-75-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-75-S Is Used
Textile Loom Feeder
Fine-tunes the yarn guide depth on a long 350 mm draw, preventing tension snags while the fixed rubber bumper softens the end impact.
Carton Flap Plow
Adjusts the plow arm angle on packaging lines, trimming the stroke by 75 mm to clear varying box heights without adding external stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-75-S with MBLJ20X350-75-S
To replace this MALJ20X350-75-S, order the MBLJ20X350-75-S. Confirm the 20 mm bore, 350 mm stroke, 75 mm adjust code, G1/8 port, and M8x1.25 rod-end thread. Mounting is FA or LB only; there is no back-cover or SDB option. Remember the adjuster is a stop, not a lock, so an external lock is required for held loads. Because this 350 mm stroke is non-standard and exceeds 300 mm, be mindful of rod-bending and side-load on long extensions.
Upgrade checklist
- ✓ Order the MBLJ20X350-75-S (same bore/stroke/adjust)
- ✓ Same 275–350 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 MBLJ20X350-75-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-75-S FAQ
Yes, it is discontinued. The direct replacement is the MBLJ20X350-75-S, which matches the bore, stroke, adjust code, and force. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 75 mm adjuster creates a usable stroke window of 275-350 mm. The adjuster is a travel stop, not a lock.
