This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X500-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X500-10-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 MALJ40X500-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 490 to 500 mm. This model is discontinued — the drop-in replacement is the MBLJ40X500-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S
The AirTAC MALJ40X500-10-S is a discontinued double-acting, single-rod adjustable-stroke mini cylinder. It features a 40 mm bore, a 500 mm stroke, and a 10 mm rear adjuster, giving a usable end-position window of 490-500 mm. It delivers 628 N push and 528 N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X500-10-S, which matches the bore, stroke, adjust code, G1/4 port, and mounting.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches on the MALJ; the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop that fine-tunes the reach without external stops, but it does not hold load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S Technical Specifications

| 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 MBLJ40X500-10-S carries the same ratings.
Theoretical Output Force (Ø40mm)

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S Is Used
Long-stroke Pallet Push-Off
Dialled reach to eject pallets from a conveyor line. The 628 N push force at 0.5 MPa handles heavy wood pallets, and the 10 mm rear stop fine-tunes the ejection point to clear guide rails.
Film Roll Alignment
Extending 500 mm to position large packaging film rolls. The fixed rubber bumper absorbs the impact of the 40 mm bore at full extension, while the adjuster trims the final resting plane to 490 mm.
Carton Flap Folding
Driving a 500 mm stroke to fold tall corrugated carton flaps. The 528 N pull force retracts the heavy mechanism, and the rear stop precisely sets the home position without adding external bolts.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S with MBLJ40X500-10-S
To replace this MALJ40X500-10-S, order the drop-in MBLJ40X500-10-S. Confirm the 40 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and FA or LB mounting (no back cover or SDB). The -S magnet requires switching from CS1-M / DS1-M to CMSG / DMSG / EMSG switches. The adjuster sets the end position but is a stop, not a lock; use an external lock for held loads. If sizing either way, the next size down is the 32 mm bore (402 N push @0.5 MPa), and the next size up does not exist in this mini series. At 500 mm stroke, the Ø16 rod is highly susceptible to side-load bending; ensure rigid guidance to prevent rod distortion.
Upgrade checklist
- ✓ Order the MBLJ40X500-10-S (same bore/stroke/adjust)
- ✓ Same 490–500 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 MBLJ40X500-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10-S FAQ
Yes, the MALJ40X500-10-S is discontinued. The exact drop-in replacement is the MBLJ40X500-10-S, which matches the 40 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 port, and force. You must update your sensor choice: the MALJ -S magnet used CS1-M / DS1-M switches, while the MBLJ uses CMSG / DMSG / EMSG.
The 10 mm adjust code gives a usable stroke window of 490-500 mm. The full force set for the 40 mm bore 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.
