This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-40-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-40-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 MALJ40X100-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-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 60 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-40-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-S
The AirTAC MALJ40X100-40-S is a discontinued double-acting single-rod mini cylinder with a rear adjustable stroke stopper. It features a 40mm bore, 100mm stroke, and a 40mm adjust code, giving a usable end-position window of 60-100mm. It delivers 628N push and 528N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X100-40-S, matching the bore, stroke, force, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade uses CMSG, DMSG, or EMSG sensors. The MALJ has threaded covers, while the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air. End impact is absorbed by a fixed rubber bumper, meaning there is no adjustable air cushion. Mounting is limited to FA or LB styles, with no back cover or SDB option.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-S Technical Specifications

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 MBLJ40X100-40-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X100-40-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-S Is Used
PCB Router Z-Axis
Dialing the 60-100mm window on this 628N cylinder sets the exact plunge depth for a PCB depaneling router bit without swapping mechanical hard stops.
Aluminum Extrusion Notch
Trim the rear stroke up to 40mm to position a 528N pull-face notching blade accurately on an aluminum profile cutting line.
Pneumatic Press Brake
Fine-tune the 100mm end position to set the bend depth on a light-gauge sheet metal press, relying on the fixed rubber bumper to absorb the 880N impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-S with MBLJ40X100-40-S
To replace this MALJ40X100-40-S, order the exact drop-in MBLJ40X100-40-S. Confirm the 40mm bore, 100mm stroke, 40mm adjust code, G1/4 port, PT thread, and FA/LB mounting. The -S magnet requires upgrading from the old CS1-M/DS1-M switches to the MBLJ's CMSG/DMSG/EMSG sensor family. Remember the adjuster is a stop, not a lock; use an external lock for held loads.
For sizing flexibility, you can step down to the 32mm bore (402N push at 0.5 MPa) if your force needs are lower, or step up to a larger standard cylinder if 628N is insufficient. At 100mm stroke, keep the rod protected from side-load bending to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X100-40-S (same bore/stroke/adjust)
- ✓ Same 60–100 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 MBLJ40X100-40-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40-S FAQ
Yes, the MALJ40X100-40-S is discontinued. The exact drop-in replacement is the MBLJ40X100-40-S, which matches the 40mm bore, 100mm stroke, 40mm adjust code, G1/4 port, and mounting. You will need to update your sensors from the old CS1-M/DS1-M to the MBLJ's CMSG/DMSG/EMSG family.
The 40mm adjust code lets you trim the rear position, creating a usable stroke window of 60-100mm. The full force set is 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock.
