This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X350-40S, 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 MALJ32X350-40S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S 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 310 to 350 mm. This model is discontinued — the direct replacement is the MBLJ32X350-40S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S
The AirTAC MALJ32X350-40S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke. The 40 mm adjust code creates a usable stroke window of 310-350 mm. The direct replacement is the MBLJ32X350-40S, matching the 32 mm bore, 350 mm stroke, G1/8 port, and mounting.
This bore 32 unit uses a 12 mm carbon-steel rod with a 20 um hard chrome plating and a rod-end thread of M10x1.25. Two upgrade details define the MBLJ transition: the MAL uses threaded covers, while the MBL uses a riveted rolling-packed body. The -S magnet on this MAL works with CS1-M / DS1-M switches, whereas the MBL replacement uses CMSG / DMSG / EMSG sensors. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no 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 MBLJ32X350-40S 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 MBLJ32X350-40S matches these values.
Model Code: Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S

| ×350 | Nominal stroke length in mm. |
| -40 | Adjustable amount: trim the end to a 310–350 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S Is Used
Textile Fabric Tensioner
Trim the 40 mm rear stop on a long 350 mm stroke to fine-tune the rest position of a fabric guide bar, maintaining consistent material tension during web feed.
Carton Flap Folder
Adjust the end position by up to 40 mm to accommodate varying box depths on a packaging line, using the 346 N pull force to fold heavy corrugated flaps precisely.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S with MBLJ32X350-40S
To replace the MALJ32X350-40S with the MBLJ32X350-40S, confirm the 32 mm bore, 350 mm stroke, 40 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back cover or SDB option). Remember the adjuster is a stop, not a lock. Because this stroke is 350 mm, minimize side-load to prevent rod bending and seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X350-40S (same bore/stroke/adjust)
- ✓ Same 310–350 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 MBLJ32X350-40S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X350-40S FAQ
Yes, the MALJ32X350-40S is discontinued. The direct replacement is the MBLJ32X350-40S, which matches the 32 mm bore, 350 mm stroke, 40 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
At 0.5 MPa it pushes with 402 N and pulls with 346 N. At 0.7 MPa it pushes with 563 N, and the maximum force is 82 kgf at 1.0 MPa. The 40 mm adjuster is a travel stop that lets you shorten the end position, creating a usable stroke window of 310-350 mm. It does not lock the load without live air.
