This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X175-100S, 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 MALJ20X175-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 75 to 175 mm. This model is discontinued — the direct replacement is the MBLJ20X175-100-S.
The AirTAC MALJ20X175-100-S is a discontinued double-acting, double-rod mini cylinder. It features a 20mm bore and a 175mm stroke. The rear adjuster lets you trim up to 100mm, creating a usable travel window of 75-175mm. The direct replacement is the MBLJ20X175-100-S, matching bore, stroke, force, G1/8 port, and mounting.
This -S magnet model originally used CS1-M/DS1-M switches; the MBLJ upgrade transitions to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion.

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 MBLJ20X175-100-S 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 MBLJ20X175-100-S matches these values.

|---|---|
| 20 | Bore size in mm (20/25/32/40). |
| ×175 | Nominal stroke length in mm. |

| 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.
Adjust the end position to strip varying cable lengths precisely, leveraging the 8mm rod and M8x1.25 thread for a custom stripper jaw.
Tune the rear stopper to crease folded leather goods at different depths, relying on the fixed rubber bumper to soften the end impact.
To replace the MALJ20X175-100-S, order the direct replacement MBLJ20X175-100-S. Confirm the 20mm bore, 175mm stroke, 100mm adjust code, G1/8 port, M8x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a travel stop, not a lock. For the 175mm stroke, prevent rod bending by ensuring rigid guide alignment to avoid side-load damage.
Upgrade checklist
Yes, the MALJ20X175-100-S is discontinued. The direct replacement is the MBLJ20X175-100-S, which matches the 20mm bore, 175mm stroke, 100mm adjust, G1/8 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 100mm adjust code creates a usable travel window from 75mm to 175mm. The adjuster is a travel stop, not a lock.
