This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-30S, 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 MALJ20X200-30-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 170 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-30-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30-S
The AirTAC MALJ20X200-30-S is a discontinued double-acting mini cylinder with a 20mm bore, 200mm stroke, and a 30mm rear travel stopper. This yields a usable extension window of 170-200mm. The direct replacement is the MBLJ20X200-30-S, matching bore, stroke, force, port and mounting.
This -S SKU has a magnet for CS1-M/DS1-M switches, while the MBLJ replacement uses CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper; the MBLJ upgrades to a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air.

| Stroke | 200 mm |
| Adjustable window | 170 – 200 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| 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 MBLJ20X200-30-S carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 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 MBLJ20X200-30-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30-S Is Used
Dispenser Valve Height
Fine-tunes the 30mm adjuster window to position a fluid dispensing nozzle precisely above an electronics package before firing the G1/8 air supply.
Thin-Wall Tube Cutoff
Acts as a depth stop for a 200mm stroke cutter, ensuring a clean face on aluminum tubing by preventing the 8mm rod from bottoming out violently.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30-S with MBLJ20X200-30-S
To replace the MALJ20X200-30-S, order the MBLJ20X200-30-S. Confirm the 20mm bore, 200mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Swap your CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors.
At 200mm stroke, the 8mm rod is vulnerable to side-load bending, so ensure rigid guidance. The rear screw sets the end position but does not lock the load without air pressure.
Upgrade checklist
- ✓ Order the MBLJ20X200-30-S (same bore/stroke/adjust)
- ✓ Same 170–200 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 MBLJ20X200-30-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30-S FAQ
Yes, the MALJ20X200-30-S is discontinued. The direct replacement is the MBLJ20X200-30-S. You must swap CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors.
The 30mm adjust code is a rear travel stop that lets you shorten the end position, creating a usable stroke window of 170-200mm. It sets the end position but does not hold the load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion.
