This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X250-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X250-100-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 150 to 250 mm. This model is discontinued — the drop-in replacement is the MBLJ40X250-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S
The AirTAC MALJ40X250-100-S is a discontinued double-acting adjustable-stroke mini cylinder. The drop-in replacement is the MBLJ40X250-100-S. This 40 mm bore unit delivers 628 N push and 528 N pull at 0.5 MPa. The -100 adjust code lets you trim up to 100 mm at the rear screw, creating a usable stroke window of 150-250 mm without external stops.
It features a G1/4 port, an M12x1.25 rod-end thread, and a fixed rubber bumper. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ replaces the old threaded covers with a riveted rolling-packed body, and the -S magnet switches from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG family.

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 MBLJ40X250-100-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S Is Used
Pallet Dispenser Indexing
Dial the exact 150-250 mm push stroke to push empty pallets off a stack. The 628 N force at 0.5 MPa easily overcomes stack friction without needing custom external spacers.
Thermoforming Press Depth
Fine-tune the forming depth on small plastic trays by adjusting the rear stop. The fixed rubber bumper absorbs the 880 N impact force at 0.7 MPa during rapid forming cycles.
Carton Flap Folding
Set a precise intermediate reach to fold heavy cardboard flaps before taping. The 100 mm adjustment window lets operators change carton sizes on the fly without swapping hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S with MBLJ40X250-100-S
To replace this MALJ40X250-100-S, install the drop-in MBLJ40X250-100-S. Confirm the 40 mm bore, 250 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and FA/LB mounting. There is no back cover or SDB option. The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG.
For sizing flexibility, step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up if you need more force. Remember the adjuster sets end position but does not lock the load. At 250 mm stroke, minimize side-load on the 16 mm rod to prevent bending; use a guide rail for heavy loads.
Upgrade checklist
- ✓ Order the MBLJ40X250-100-S (same bore/stroke/adjust)
- ✓ Same 150–250 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 MBLJ40X250-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X250-100-S FAQ
Yes, the MALJ40X250-100-S is discontinued. The exact drop-in replacement is the MBLJ40X250-100-S, which matches the 40 mm bore, 250 mm stroke, 100 mm adjust code, G1/4 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design and shifts the -S magnet to CMSG / DMSG / EMSG switches.
The usable stroke window is 150-250 mm, set by trimming the rear stopper up to 100 mm. Force output is 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock, so it will not hold a load without air pressure.
