This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X175-10S, 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 MALJ20X175-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S 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 165 to 175 mm. This model is discontinued — the direct replacement is the MBLJ20X175-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S
The AirTAC MALJ20X175-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke. It provides a usable travel window of 165-175 mm by trimming up to 10 mm at the rear screw.
This -S variant carries a magnet for CS1-M or DS1-M reed switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and swaps the original threaded covers for a riveted rolling-packed body. The adjuster functions strictly as a travel stop to fine-tune depth without external hardware, not as a lock to hold loads without live air. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X175-10-S |
| Bore size | Ø20 mm |
| Stroke | 175 mm |
| Adjustable window | 165 – 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 |
| Proof pressure | 1.5 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 MBLJ20X175-10-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 MBLJ20X175-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S Is Used
Dispenser Nozzle Depth Trim
Trims up to 10 mm at the rear stop to set exact fluid deposit depth on varying bottle heights, avoiding external spacers on the machine frame.
Lightweight Label Wiper
Wipes labels onto small cartons using the 132 N pull force, adjusting the end position by a few millimeters to match different box widths.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S with MBLJ20X175-10-S
To replace the MALJ20X175-10-S with the MBLJ20X175-10-S, confirm the 20 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 PT port, and M8x1.25 rod thread. Mounting is limited to FA or LB foot brackets, as there is no back cover or SDB option. You must also update your sensors from the older CS1-M/DS1-M family to CMSG/DMSG/EMSG switches.
At 175 mm stroke on an 8 mm rod, be mindful of rod-bending side loads. The rear adjuster sets the end position but cannot hold a load without continuous air pressure.
Upgrade checklist
- ✓ Order the MBLJ20X175-10-S (same bore/stroke/adjust)
- ✓ Same 165–175 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 MBLJ20X175-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10-S FAQ
Yes, the MALJ20X175-10-S is discontinued. The direct replacement is the MBLJ20X175-10-S, which matches the 20 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, and mounting. You will need to switch from CS1-M/DS1-M sensors to CMSG/DMSG/EMSG switches.
The usable stroke window is 165-175 mm. The 10 mm rear adjuster is a travel stop, not a lock.
