This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X225-10S, 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 MALJ20X225-10-S

This model is discontinued — the direct replacement is the MBLJ20X225-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-10-S
The AirTAC MALJ20X225-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke. The -10 code provides a 10 mm trim, yielding a usable extension window of 215-225 mm. The direct replacement is the MBLJ20X225-10-S, matching the G1/8 port and force ratings.
This -S SKU includes a magnet for legacy CS1-M / DS1-M switches; the MBLJ upgrade moves to CMSG / DMSG / EMSG sensors and swaps the MAL threaded covers for a riveted rolling-packed body. The rear adjuster acts as a travel stop to fine-tune reach without external bolts, but it does not hold 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 MBLJ20X225-10-S carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 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 MBLJ20X225-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-10-S Is Used
Label Applicator Wipe
Trims the rear stop by 10 mm to tune the wipe stroke for varying box widths without adding external physical stops.
Foam Cutting Gate
Sets a precise 220 mm blade entry into foam blocks, relying on the fixed rubber bumper to absorb the end-of-stroke impact.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-10-S with MBLJ20X225-10-S
To replace this MALJ20X225-10-S, order the MBLJ20X225-10-S. Confirm the 20 mm bore, 225 mm stroke, 10 mm adjust code, PT G1/8 port, and M8x1.25 rod thread. Mounting is Basic, FA or LB only (no back cover or SDB). The -S magnet means a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. The adjuster sets end position but is not a lock.
At 225 mm, this 8 mm rod is long; minimize side-load to prevent rod bending and seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X225-10-S (same bore/stroke/adjust)
- ✓ Same 215–225 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 MBLJ20X225-10-S instead of this discontinued model.
