This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X275-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X275-100-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 MALJ40X275-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-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 175 to 275 mm. This model is discontinued — the drop-in replacement is the MBLJ40X275-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S
The AirTAC MALJ40X275-100-S is a discontinued double-acting single-rod cylinder with a 40mm bore and a 275mm stroke. It provides 628N of push force at 0.5MPa. The rear screw stopper lets you trim up to 100mm, creating a usable stroke window of 175-275mm. The exact drop-in replacement is the MBLJ40X275-100-S.
This -S variant has a magnet for CS1-M or DS1-M switches, though the MBLJ upgrade uses CMSG/DMSG/EMSG sensors and a riveted rolling-packed body instead of the MAL threaded covers. The adjuster is a travel stop, not a lock, and end impacts are softened by a fixed rubber bumper. With a 275mm stroke, minimize side loads to prevent rod bending.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S |
|---|---|

| Bore size | Ø40 mm |
| Stroke | 275 mm |
| Adjustable window | 175 – 275 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

| 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 MBLJ40X275-100-S carries the same ratings.
Theoretical Output Force (Ø40mm)

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S Is Used
Injection Mold Ejection
Dials the exact 175-275mm ejection reach for plastic parts, using the 628N push force to clear the mold without overtravel.
Packaging Flap Folding
Trims the rear stopper to tuck carton flaps at varying depths, relying on the fixed rubber bumper to absorb the end impact.
Wood Router Profiling
Sets a precise depth stop for a routing fixture, using the 880N push at 0.7MPa to hold the tool head against vibration.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S with MBLJ40X275-100-S
To replace this MALJ40X275-100-S, specify the MBLJ40X275-100-S to match the 40mm bore, 275mm stroke, 100mm adjust code, G1/4 port, and FA/LB mounting. The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. If you need less force, step down to a 32mm bore (402N push at 0.5MPa); if you need more, 40mm is the largest MALJ size available. The adjuster sets the end position but will not hold a load without live air.
Upgrade checklist
- ✓ Order the MBLJ40X275-100-S (same bore/stroke/adjust)
- ✓ Same 175–275 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 MBLJ40X275-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-100-S FAQ
Yes, the MALJ40X275-100-S is discontinued. The exact drop-in replacement is the MBLJ40X275-100-S, which matches the 40mm bore, 275mm stroke, 100mm adjust code, and G1/4 port. The MBLJ uses a riveted body and CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The usable stroke window is 175-275mm. At 0.5MPa it provides 628N push and 528N pull. At 0.7MPa push is 880N, and the maximum force is 128kgf at 1.0MPa. The rear adjuster is a travel stop, not a lock, and cannot hold a load without air pressure.
