This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-50S, 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 MALJ20X160-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 110 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-50-S.
The AirTAC MALJ20X160-50-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable travel stop. It trims up to 50 mm at the rear, yielding a usable end-position window of 110-160 mm. The direct replacement is the MBLJ20X160-50-S, matching bore, stroke, adjust code, and force.
This SKU includes the -S magnet for legacy CS1-M / DS1-M switches, whereas the MBLJ replacement uses CMSG / DMSG / EMSG sensors. The MALJ uses a fixed rubber bumper to soften end impact and threaded covers, while the MBLJ upgrades to a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air.

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 MBLJ20X160-50-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 MBLJ20X160-50-S matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Fine-tune the reach into a leather skiving machine, trimming up to 50 mm at the rear to adjust the blade angle contact point, ensuring the 132 N pull retracts the gauge consistently.
Set the exact extension on a solder paste dispenser to alter the nozzle pitch distance, using the fixed rubber bumper to absorb the repeated end impact during rapid 30-800 mm/s cycling.
Replace this MALJ20X160-50-S directly with the MBLJ20X160-50-S. Confirm the bore 20, 160 mm stroke, 50 mm adjust code, G1/8 port, and M8x1.25 rod-end thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. The -S magnet on your old unit used CS1-M / DS1-M switches, so you must update to CMSG / DMSG / EMSG sensors for the MBLJ. The rear adjuster is a travel stop, not a lock.
At 160 mm stroke, be mindful of rod-bending and side-load on the Ø8 mm rod; use a guide rail to prevent binding.
Upgrade checklist
Yes, the MALJ20X160-50-S is discontinued. The direct replacement is the MBLJ20X160-50-S, matching the bore 20, 160 mm stroke, 50 mm adjust code, and G1/8 port. You must swap your old CS1-M / DS1-M switches for CMSG / DMSG / EMSG sensors, as the MBLJ uses a riveted rolling-packed body instead of threaded covers.
The 50 mm adjust code lets you trim the rear position, creating a usable stroke window from 110 mm to 160 mm. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact only.
