This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-100S, 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).
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-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 60 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-100-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-S
The AirTAC MALJ20X160-100-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. A 100mm rear adjuster trims the end position, creating a usable stroke window of 60-160mm. The direct replacement is the MBLJ20X160-100-S, matching bore, stroke, force, G1/8 port, and mounting.
The rear adjuster sets travel but is a stop, not a lock; it will not hold a load without live air. This -S SKU includes a magnet for CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ features a riveted rolling-packed body. Both lack a back cover and SDB, restricting mounting to FA or LB.

| 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 MBLJ20X160-100-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 MBLJ20X160-100-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-S Is Used
Dispenser Valve Actuation
Fine-tunes the shot size by limiting the extend stroke, preventing over-travel on pneumatic glue dispensers.
Wire Straightener Feed
Sets the precise pull-back distance for feeding raw wire stock into a former, adjusting the window without adding external stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-S with MBLJ20X160-100-S
To replace this MALJ20X160-100-S, order the direct replacement MBLJ20X160-100-S. Confirm the 20mm bore, 160mm stroke, 100mm adjust code, G1/8 port, PT thread, and FA/LB mounting. Remember the adjuster is a travel stop, not a lock; add an external lock to hold loads. The -S magnet changes sensor families from CS1-M / DS1-M to CMSG / DMSG / EMSG.
For sizing, stepping down to the 20mm bore is the minimum standard, but you can reduce the adjust code to a 50mm window for finer reach. At 160mm stroke, minimize side-load to prevent rod bending, as the 8mm rod lacks inherent guidance.
Upgrade checklist
- ✓ Order the MBLJ20X160-100-S (same bore/stroke/adjust)
- ✓ Same 60–160 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 MBLJ20X160-100-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-100-S FAQ
Yes, the MALJ20X160-100-S is discontinued. The direct replacement is the MBLJ20X160-100-S, which matches the 20mm bore, 160mm stroke, 100mm adjust code, force, G1/8 port, and mounting. You will only need to swap the CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches.
The 100mm adjust code allows trimming the rear travel stop, creating a usable stroke window of 60-160mm. The adjuster is a stop, not a lock, and cannot hold a load without air.
