This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X225-20S, 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 MALJ32 Adjustable Mini Cylinder MALJ32X225-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-20-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 205 to 225 mm. This model is discontinued — the direct replacement is the MBLJ32X225-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-20-S
The AirTAC MALJ32X225-20-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable-stroke stopper. The -20 code means you can trim up to 20 mm at the rear, creating a usable end-position window of 205-225 mm. The direct replacement is the MBLJ32X225-20-S, matching the bore, stroke, adjust code, and G1/8 port.
This SKU includes a magnet (-S) for position sensing. During the upgrade to the MBLJ, the older CS1-M / DS1-M switches are replaced by the CMSG / DMSG / EMSG sensor family, and the original threaded covers are superseded by a riveted rolling-packed body. The cylinder relies on a fixed rubber bumper, not an air cushion, so the adjustable stroke feature only sets the travel end position. The adjuster is a mechanical stop, not a lock, and it will not hold a load without live air pressure.

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 MBLJ32X225-20-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 MBLJ32X225-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-20-S Is Used
Carton Flap Folder
Adjust the end position by up to 20 mm on a packaging line flap folder to accommodate varying box heights, relying on the 346 N pull force to retract the folding arm.
Pneumatic Press Tonnage Set
Fine-tune the bottom position of a small assembly press to prevent over-travel when crimping delicate contacts, using the fixed rubber bumper to soften the final impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-20-S with MBLJ32X225-20-S
To replace this MALJ32X225-20-S with the MBLJ32X225-20-S, confirm the 32 mm bore, 225 mm stroke, 20 mm adjust code, PT thread, and FA or LB mounting (there is no back cover or SDB option). Remember the rear adjuster is a travel stop, not a lock. At a 225 mm stroke, long rod extension increases susceptibility to side-load bending, so ensure rigid guidance to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ32X225-20-S (same bore/stroke/adjust)
- ✓ Same 205–225 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 MBLJ32X225-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-20-S FAQ
Yes, the MALJ32X225-20-S is discontinued. The direct replacement is the MBLJ32X225-20-S, which matches the 32 mm bore, 225 mm stroke, 20 mm adjust code, and G1/8 port. The MBLJ uses a riveted rolling-packed body instead of threaded covers, and if you use the -S magnet, you must upgrade from the old CS1-M / DS1-M switches to the CMSG / DMSG / EMSG sensor family.
At 0.7 MPa, the push force is 563 N, and the maximum force is 82 kgf at 1.0 MPa. The -20 adjust code allows you to trim the stroke by up to 20 mm, giving a usable end-position window of 205-225 mm. The adjuster acts only as a travel stop and does not hold the load without air pressure.
