This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-75S, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S
The AirTAC MALJ20X200-75-S is a discontinued double-acting mini cylinder with a rear adjustable stroke. It provides a usable stroke window of 125-200 mm by trimming up to 75 mm at the rear screw. The direct replacement is the MBLJ20X200-75-S, matching bore, stroke, force, and G1/8 port.
This -S SKU uses a CS1-M / DS1-M magnet sensor, whereas the MBLJ replacement upgrades to CMSG / DMSG / EMSG switches. The MALJ features threaded covers and a fixed rubber bumper; the adjuster is a travel stop, not a load lock. It has no back cover or SDB, accepting FA or LB mounting only.

| 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 MBLJ20X200-75-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 MBLJ20X200-75-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S Is Used
Small Parts Ejector
Fine-tune the ejection depth on a pick-and-place router, preventing the 8 mm rod from overtraveling and damaging delicate fixtures.
Label Applicator Wipe
Adjust the rear stopper to set the exact wipe-down distance for different carton depths, relying on the fixed rubber bumper for soft end impact.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S with MBLJ20X200-75-S
To replace this MALJ20X200-75-S, order the MBLJ20X200-75-S. Confirm the 20 mm bore, 200 mm stroke, 75 mm adjust code, G1/8 port, and FA/LB mounting. The -S magnet changes sensor families from CS1-M / DS1-M to CMSG / DMSG / EMSG. The rear adjuster sets the end position but does not hold a load without live air; use an external lock for holding.
At 200 mm stroke, prevent rod bending by avoiding side loads and guiding the load rigidly.
Upgrade checklist
- ✓ Order the MBLJ20X200-75-S (same bore/stroke/adjust)
- ✓ Same 125–200 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 MBLJ20X200-75-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S FAQ
Yes, the MALJ20X200-75-S is discontinued. The direct replacement is the MBLJ20X200-75-S, which matches the 20 mm bore, 200 mm stroke, 75 mm adjust code, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 75 mm adjust code lets you trim the rear travel stop, creating a usable stroke window from 125 mm to 200 mm. The adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.
