This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X175-75, 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 MALJ20X175-75
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 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 100 to 175 mm. This model is discontinued — the direct replacement is the MBLJ20X175-75.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75
The AirTAC MALJ20X175-75 is a discontinued 20mm bore, double-acting mini cylinder with a 175mm stroke and a 75mm rear adjustable stroke stopper. This gives a usable end-position window of 100-175mm. The direct replacement is the MBLJ20X175-75, matching the bore, stroke, G1/8 port, and force.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure. The fixed rubber bumper softens end impact, but note this is an adjustable stroke, not an adjustable cushion. The original MALJ uses threaded covers and a CS1-M/DS1-M sensor track, while the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X175-75 |
| Bore size | Ø20 mm |
| Stroke | 175 mm |
| Adjustable window | 100 – 175 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

| 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 MBLJ20X175-75 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 MBLJ20X175-75 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 Is Used
Wire Crimp Terminal Feed
Trims the pusher stroke to strip and crimp 18 AWG wire in automated harness machines, relying on the fixed rubber bumper to soften the 175mm rapid extend impact.
Dispenser Valve Shut-Off
Sets the exact needle lift for low-viscosity epoxy on a packaging line, adjusting the 75mm stopper window to prevent fluid shear without needing external rod locks.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 with MBLJ20X175-75
To replace the MALJ20X175-75, order the MBLJ20X175-75. Confirm the 20mm bore, 175mm stroke, 75mm 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. Because this SKU has no -S magnet, it cannot hold a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need sensing. The rear adjuster is a travel stop, not a lock.
For sizing flexibility, stepping down to the 20mm bore's neighbour is not an option as 20mm is the smallest available. With a 175mm stroke on an 8mm rod, be mindful of side-load and rod-bending forces; ensure rigid guidance to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X175-75 (same bore/stroke/adjust)
- ✓ Same 100–175 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 MBLJ20X175-75 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-75 FAQ
Yes, the MALJ20X175-75 is discontinued. The direct replacement is the MBLJ20X175-75, which matches the 20mm bore, 175mm stroke, 75mm adjust code, G1/8 port, and 32 kgf max force. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 75mm rear adjuster creates a usable stroke window from 100mm to 175mm. Note that this non-magnet SKU cannot accept a sensor, and the adjuster is a travel stop, not a load lock.
