This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X175-10, 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).

The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X175-10 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 165 to 175 mm. This model is discontinued — the direct replacement is the MBLJ20X175-10.
The AirTAC MALJ20X175-10 is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. A rear stopper screw lets you trim the end position by up to 10 mm, yielding a usable stroke window of 165-175 mm. The direct replacement is the MBLJ20X175-10, matching the bore, stroke, adjust code, port, and mounting.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact, and the carbon-steel rod with a 20 um hard chrome plating resists wear. Note that the MALJ uses threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body.

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 carries the same ratings.
| 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 matches these values.

|---|---|
| 20 | Bore size in mm (20/25/32/40). |
| ×175 | Nominal stroke length in mm. |
| -10 | Adjustable amount: trim the end to a 165–175 mm window. |
| 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.
Fine-tune the rest position of a fabric guide arm by up to 10 mm, ensuring consistent material tension across the roller without needing to remount the cylinder body.
Adjust the kick stroke to drop plastic moldings into a secondary chute, using the 132 N pull force to retract the 8 mm rod clear of the press cavity before the next cycle.
To replace the MALJ20X175-10, order the direct replacement MBLJ20X175-10. Confirm the 20 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need one. Remember the adjuster is a stop, not a lock.
With a 175 mm stroke, minimize side-load to prevent rod bending; the 8 mm rod needs straight alignment. The fixed rubber bumper absorbs end impact, but use an external lock for holding loads.
Upgrade checklist
Yes, the MALJ20X175-10 is discontinued. The direct replacement is the MBLJ20X175-10, which matches the 20 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and supports CMSG/DMSG/EMSG sensors, though this original non-S SKU cannot take a sensor.
The 10 mm adjust code creates a usable stroke window of 165-175 mm via a rear travel stop. At 0.7 MPa, push is 220 N, and the maximum force is 32 kgf at 1.0 MPa. The adjuster sets the end position but does not hold load without air.
