This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-30S, 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 MALJ32X300-30-S
The AirTAC MALJ32 Adjustable Mini Cylinder MALJ32X300-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 270 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-30-S
The AirTAC MALJ32X300-30-S is a discontinued double-acting, double-rod mini cylinder with a 30 mm rear adjustable stroke stopper, yielding a usable end-position window of 270-300 mm. The direct replacement is the MBLJ32X300-30-S, matching the 32 mm bore, 300 mm stroke, G1/8 port, and mounting.
The rear adjuster sets travel limits but is a stop, not a lock, so it will not hold a load without live air. This -S SKU includes a magnet for CS1-M / DS1-M switches; upgrading to the MBLJ32X300-30-S shifts you to CMSG / DMSG / EMSG sensors and a riveted rolling-packed body instead of the MALJ's threaded covers. A fixed rubber bumper absorbs end impacts, but with a 300 mm stroke, you must minimize rod side-load to prevent bending.

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 MBLJ32X300-30-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 MBLJ32X300-30-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-30-S Is Used
Carton Flap Folder
Adjust the end position by up to 30 mm on a packaging line folder to clear varying carton heights, using the 346 N pull to snap flaps without crushing the board.
Leather Press Tensioner
Fine-tune the 300 mm stroke on a leather embossing press to apply exact contact pressure, letting the fixed rubber bumper absorb the impact of the 12 mm rod at cycle end.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-30-S with MBLJ32X300-30-S
To replace the MALJ32X300-30-S, order the direct replacement MBLJ32X300-30-S. Confirm the 32 mm bore, 300 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes the sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a travel stop, not a lock.
At 300 mm, rod side-load causes bending; use a guide to prevent binding.
Upgrade checklist
- ✓ Order the MBLJ32X300-30-S (same bore/stroke/adjust)
- ✓ Same 270–300 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 MBLJ32X300-30-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-30-S FAQ
Yes, the MALJ32X300-30-S is discontinued. The direct replacement is the MBLJ32X300-30-S, matching the 32 mm bore, 300 mm stroke, 30 mm adjust code, G1/8 port, and FA/LB mounting. The upgrade shifts from threaded covers to a riveted rolling-packed body, and the -S magnet changes sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 30 mm adjust code creates a usable stroke window of 270-300 mm. The adjuster is a travel stop, not a lock, so it cannot hold a load without air.
