This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X25-20-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 MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-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 5 to 25 mm. This model is discontinued — the direct replacement is the MBLJ25X25-20-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-S
The AirTAC MALJ25X25-20-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. The direct replacement is the MBLJ25X25-20-S, matching the 25 mm bore, 25 mm stroke, 20 mm adjust code, G1/8 port, and FA/LB mounting. The rear adjuster lets you trim the end position by up to 20 mm, creating a usable stroke window of 5-25 mm for precise depth control without adding external stops.
It uses a fixed rubber bumper, not an adjustable air cushion. The adjuster sets the end position but is a travel stop, not a lock; it will not hold a load without live air. This -S variant has a magnet for CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors and uses a riveted rolling-packed body instead of threaded covers.

| Adjustable window | 5 – 25 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |

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 MBLJ25X25-20-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 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 MBLJ25X25-20-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-S Is Used
Wire Crimp Tool Stop
Fine-tunes the crimp height on a benchtop terminal applicator by adjusting the rear stop, ensuring the 206 N pull force retracts the anvil cleanly between cycles.
Label Applicator Wipe Mechanism
Sets a precise wipe distance of 15 mm within the 5-25 mm window to press labels onto small cartons, relying on the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-S with MBLJ25X25-20-S
To replace this MALJ25X25-20-S, order the MBLJ25X25-20-S. Confirm the 25 mm bore, 25 mm stroke, 20 mm adjust code, PT/G1/8 port, and M10x1.25 rod-end thread. Mounting remains Basic, FA, or LB only; there is no back-cover or SDB option. The -S magnet means you must upgrade your switches from the older CS1-M / DS1-M to the MBLJ's CMSG / DMSG / EMSG family. Remember the rear adjuster is a travel stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X25-20-S (same bore/stroke/adjust)
- ✓ Same 5–25 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 MBLJ25X25-20-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-20-S FAQ
Yes, the MALJ25X25-20-S is discontinued. The direct replacement is the MBLJ25X25-20-S, which shares the same 25 mm bore, 25 mm stroke, 20 mm adjust code, G1/8 port, and FA/LB mounting. You will need to upgrade your sensors from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The 20 mm adjust code lets you trim the 25 mm stroke down to a 5-25 mm usable window. The adjuster is a travel stop, not a lock.
