This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X130-20-S, 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 MALJ20X130-20-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 110 to 130 mm. This model is discontinued — the direct replacement is the MBLJ20X130-20-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-20-S
The AirTAC MALJ20X130-20-S is a discontinued double-acting, double-rod mini cylinder with a 20 mm bore and 130 mm stroke. The -20 adjust code lets you trim the rear travel stop by up to 20 mm, creating a usable 110-130 mm end-position window without external stops. The direct replacement is the MBLJ20X130-20-S.
This adjustable stroke is a travel stop, not a lock; it will not hold a load without live air. The MALJ uses a fixed rubber bumper, not an adjustable air cushion. Upgrading to the MBLJ20X130-20-S changes the threaded covers to a riveted rolling-packed body, and the -S magnet switches from the older CS1-M/DS1-M sensors to the CMSG/DMSG/EMSG family.

| 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 MBLJ20X130-20-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 MBLJ20X130-20-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-20-S Is Used
Connector Molding Press
Sets precise mold closure at 130 mm while the 132 N pull retracts the upper die, preventing flash on plastic housings.
Leaded Component Forming
Bends axial resistor leads to exact lengths by stopping the 8 mm rod short, relying on the fixed rubber bumper for soft impact.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-20-S with MBLJ20X130-20-S
To replace this MALJ20X130-20-S, order the exact direct replacement MBLJ20X130-20-S. Confirm the 20 mm bore, 130 mm stroke, -20 adjust code, G1/8 port, M8x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Remember the rear adjuster is a stop, not a lock. For a 130 mm stroke, use guide bushings to prevent rod bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ20X130-20-S (same bore/stroke/adjust)
- ✓ Same 110–130 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 MBLJ20X130-20-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-20-S FAQ
Yes, the MALJ20X130-20-S is discontinued. The direct replacement is the MBLJ20X130-20-S, matching the 20 mm bore, 130 mm stroke, 20 mm adjuster, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The -20 adjust code creates a usable stroke window of 110-130 mm. The adjuster acts only as a travel stop and does not hold the load without air pressure.
