This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X60-40-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X60-40-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 MALJ40X60-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40-S 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 20 to 60 mm. This model is discontinued — the drop-in replacement is the MBLJ40X60-40-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40-S
The AirTAC MALJ40X60-40-S is a discontinued double-acting, single-rod mini cylinder with a 40 mm bore, 60 mm stroke, and a 40 mm rear adjustable stopper. The adjust code lets you trim the end position by up to 40 mm, creating a usable stroke window of 20-60 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X60-40-S, which matches the bore, stroke, force, and G1/4 port.
This -S variant includes a magnet for legacy CS1-M or DS1-M reed switches; the MBLJ replacement uses newer CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper, while the MBLJ upgrades to a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ40X60-40-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40-S Is Used
Packaging Flap Folding
Dialing the 20-60 mm window on a 40 mm bore lets a packaging line fine-tune cardboard flap folding without adding external physical stops, using 628 N of push force.
PCB Test Head Depth
Set precise end-of-travel for an electronics test head. The 40 mm rear adjuster acts as a travel stop to prevent probe over-travel on varying board thicknesses.
Bottle Sorting Diverter
A beverage conveyor uses the 528 N pull force to actuate a sorting gate. The fixed rubber bumper softens the 60 mm stroke end impact without needing an adjustable air cushion.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40-S with MBLJ40X60-40-S
To replace the MALJ40X60-40-S, order the drop-in MBLJ40X60-40-S. Confirm the 40 mm bore, 60 mm stroke, 40 mm adjust code, G1/4 port, and PT thread form. Mounting is limited to FA or LB; there is no back cover or SDB option. The -S magnet means you must switch from old CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors. The adjuster is a travel stop, not a lock. If sizing force, the next size down is the 32 mm bore (402 N push at 0.5 MPa), and the next size up is beyond this mini range, so this 40 mm bore (628 N push) is the heaviest available.
Upgrade checklist
- ✓ Order the MBLJ40X60-40-S (same bore/stroke/adjust)
- ✓ Same 20–60 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 MBLJ40X60-40-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40-S FAQ
Yes, the MALJ40X60-40-S is discontinued. The exact drop-in replacement is the MBLJ40X60-40-S, which matches the 40 mm bore, 60 mm stroke, 40 mm adjust code, 628 N push force, and G1/4 port. You must upgrade your sensors from the old CS1-M/DS1-M switches to CMSG/DMSG/EMSG models.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it provides 880 N push, with a maximum force of 128 kgf at 1.0 MPa. The 40 mm adjust code allows trimming up to 40 mm from the 60 mm stroke, giving a usable window of 20-60 mm. The adjuster is a travel stop, not a lock.
