This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-20, 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 MALJ32X450-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 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 430 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20
The AirTAC MALJ32X450-20 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 20 mm at the rear, giving a usable end-position window of 430-450 mm. The direct replacement is the MBLJ32X450-20, matching bore, stroke, force, and port.
This SKU has no magnet and cannot take a position sensor. The adjuster sets the end position but does not hold load without live air; add an external lock for held loads. It uses a fixed rubber bumper, not an adjustable air cushion. Two upgrade facts: the MALJ uses threaded covers while the MBLJ uses a riveted rolling-packed body, and because this is a no-S SKU, you avoid the older CS1-M/DS1-M switch migration to CMSG/DMSG/EMSG entirely.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X450-20 |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 430 – 450 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 MBLJ32X450-20 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 MBLJ32X450-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 Is Used
Thermoforming Plug Assist
Fine-tune the 450 mm reach on a plug assist to stretch heated plastic sheet evenly, relying on the fixed rubber bumper to soften the 563 N end impact at 0.7 MPa.
Carton Flap Tucking Arm
Adjust the rear stopper by up to 20 mm to tuck varying carton flap sizes on a packaging line, using the 346 N pull force to retract the arm cleanly between cycles.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 with MBLJ32X450-20
To replace the MALJ32X450-20 with the MBLJ32X450-20, confirm the 32 mm bore, 450 mm stroke, 20 mm adjust code, G1/8 port, and M10x1.25 rod-end thread. Mounting is FA or LB only; there is no back cover or SDB option. The adjuster is a travel stop, not a lock.
At 450 mm stroke, the 12 mm rod is susceptible to bending under side loads. Use hardened guide rails to prevent rod deflection and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X450-20 (same bore/stroke/adjust)
- ✓ Same 430–450 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 MBLJ32X450-20 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20 FAQ
Yes, the MALJ32X450-20 is discontinued. The direct replacement is the MBLJ32X450-20, which matches the 32 mm bore, 450 mm stroke, 20 mm adjust code, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design instead of threaded covers.
The 20 mm adjust code allows trimming the rear position, giving a usable stroke window of 430-450 mm. The adjuster is a travel stop, not a lock; it cannot hold a load without live air.
