This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X175-40S, 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 MALJ32X175-40-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 135 to 175 mm. This model is discontinued — the direct replacement is the MBLJ32X175-40-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-40-S
The AirTAC MALJ32X175-40-S is a discontinued double-acting double-rod cylinder with a 32mm bore and a 175mm stroke. It is discontinued and the direct replacement is the MBLJ32X175-40-S. The 40mm rear adjuster gives a usable stroke window of 135-175mm, letting you dial in the exact reach without external stops.
This -S model has a magnet for CS1-M or DS1-M switches, whereas the MBLJ replacement uses CMSG, DMSG or EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper; the MBLJ upgrades to a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air pressure.

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 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 MBLJ32X175-40-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 MBLJ32X175-40-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-40-S Is Used
Carton Flap Folder
Adjust the end position on the fly for different box heights on a packaging line, trimming up to 40mm so the 346N pull force folds flaps perfectly without crushing the corrugated board.
Textile Fabric Tensioner
Fine-tune the guide rail reach on a weaving machine, using the 175mm stroke to compensate for fabric roll width changes while the fixed rubber bumper absorbs the high-speed end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-40-S with MBLJ32X175-40-S
To replace this MALJ32X175-40-S with the MBLJ32X175-40-S, confirm the 32mm bore, 175mm stroke, 40mm adjust code, G1/8 port, PT thread, and FA or LB mounting. You cannot use a back-cover or SDB code. The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock.
At 175mm stroke, the 12mm rod is long enough that side-load alignment is critical to prevent rod bending and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X175-40-S (same bore/stroke/adjust)
- ✓ Same 135–175 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 MBLJ32X175-40-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-40-S FAQ
Yes, the MALJ32X175-40-S is discontinued. The direct replacement is the MBLJ32X175-40-S, which matches the 32mm bore, 175mm stroke, 40mm adjust code, G1/8 port, and mounting. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The bore is 32mm. The 40mm adjuster creates a usable stroke window of 135-175mm. Remember the adjuster is a travel stop, not a lock, and it cannot hold a load without air pressure.
