This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X500-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X500-100-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 MALJ40X500-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-100-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 400 to 500 mm. This model is discontinued — the drop-in replacement is the MBLJ40X500-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-100-S
The AirTAC MALJ40X500-100-S is a discontinued double-acting single-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable travel window of 400-500 mm by trimming up to 100 mm at the rear screw. This 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X500-100-S, matching the bore, stroke, adjust code, and G1/4 port.
This SKU includes a magnet (-S) for CS1-M / DS1-M switches, whereas the MBLJ replacement uses CMSG / DMSG / EMSG sensors. The legacy MALJ features threaded covers, while the MBLJ upgrades to a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. Impact is softened by a fixed rubber bumper, as there is no air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-100-S Is Used
Long-Reach Pallet Dispenser
Dial the exact 400-500 mm reach to push empty pallets into a packaging line, using the 628 N push force to overcome stack friction without over-traveling.
Automated Door Opening Mechanism
Fine-tune the opening depth on heavy machine tool doors by trimming the 100 mm rear stop, preventing the 16 mm rod from slamming against the mechanical end stop.
Welding Fixture Depth Stop
Set a precise 420 mm insertion depth for locating heavy steel frames in a robotic weld cell, relying on the fixed rubber bumper to absorb the end-of-stroke impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-100-S with MBLJ40X500-100-S
To replace the MALJ40X500-100-S with the MBLJ40X500-100-S, verify the 40 mm bore, 500 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and FA or LB mounting (no back cover or SDB is used). If you need to step down, the 32 mm bore offers 402 N push at 0.5 MPa. If you need to step up, the 40 mm is the largest MALJ bore available, so you would migrate to an ISO 15552 cylinder for higher forces. Note the -S magnet sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. Because the stroke is 500 mm, minimize side-load to prevent rod bending and premature seal wear. The adjuster is a stop, not a lock; add an external locking device for holding loads without air.
Upgrade checklist
- ✓ Order the MBLJ40X500-100-S (same bore/stroke/adjust)
- ✓ Same 400–500 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 MBLJ40X500-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-100-S FAQ
Yes, the MALJ40X500-100-S is discontinued. The exact drop-in replacement is the MBLJ40X500-100-S, which matches the 40 mm bore, 500 mm stroke, 100 mm adjust code, and G1/4 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.
The -100 adjust code allows you to trim up to 100 mm at the rear, creating a usable stroke window of 400-500 mm. The 40 mm bore provides a push force of 628 N and pull of 528 N 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.
