This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X350-10, 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 MALJ20X350-10
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 340 to 350 mm. This model is discontinued — the direct replacement is the MBLJ20X350-10.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10
The AirTAC MALJ20X350-10 is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It has a 20mm bore, a 350mm non-standard stroke (exceeding the 300mm standard max, so it is made-to-order), and a 10mm rear adjuster. This yields a usable end-position window of 340-350mm. The direct replacement is the MBLJ20X350-10, matching the bore, stroke, adjust code, G1/8 port, and mounting.
The rear screw is a travel stop to fine-tune the end position without external hardware; it is not a lock and will not hold a load without live air. This SKU lacks the -S magnet, so it cannot accept a CS1-M or DS1-M position sensor. Upgrading to the MBLJ moves from threaded covers to a riveted rolling-packed body, and if you later need a sensor, the MBLJ uses the newer CMSG/DMSG/EMSG switches. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10 Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 350 mm |
| Adjustable window | 340 – 350 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 MBLJ20X350-10 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 MBLJ20X350-10 matches these values.

| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10 Is Used
Long-Reach Test Probe
Extend a 350mm probe to a dialled depth for connector continuity testing, where the non-standard length reaches deep into a test fixture and the stopper sets the exact touch-point.
Film Web Tensioning
Set a long-stroke tensioning roller position in a packaging machine, trimming the end position up to 10mm to balance web stretch without adding external mechanical stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10 with MBLJ20X350-10
To replace this MALJ20X350-10, order the direct replacement MBLJ20X350-10. Confirm the 20mm bore, 350mm stroke, 10mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back-cover or SDB option). Since this is a non-S SKU, it cannot take a sensor. Because the 350mm stroke exceeds the 300mm standard maximum, it is non-standard and highly susceptible to side-load and rod-bending—ensure strict load alignment or add external guide rails.
Upgrade checklist
- ✓ Order the MBLJ20X350-10 (same bore/stroke/adjust)
- ✓ Same 340–350 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 MBLJ20X350-10 instead of this discontinued model.
