This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X275-10-S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X275-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-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 265 to 275 mm. This model is discontinued — the direct replacement is the MBLJ40X275-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-S
The AirTAC MALJ40X275-10-S is a discontinued double-acting double-rod cylinder with a 40mm bore and 275mm stroke. It provides a usable extension window of 265-275mm via a 10mm rear screw stopper. The direct replacement is the MBLJ40X275-10-S, matching the G1/4 port, M12x1.25 rod thread, and 128kgf max force.
This SKU uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. For your upgrade, the older MAL threaded covers and CS1-M/DS1-M sensors change to a riveted rolling-packed body using CMSG/DMSG/EMSG switches on the MBLJ.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-S Technical Specifications

| Replacement | MBLJ40X275-10-S |
| Bore size | Ø40 mm |
| Stroke | 275 mm |
| Adjustable window | 265 – 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 MBLJ40X275-10-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X275-10-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-S Is Used
Automated Welding Torch
Fine-tune the 10mm rear stopper to position a MIG torch precisely over a seam, ensuring the 528N retract pull retracts the 275mm rod cleanly away from heat splatter.
Carton Flap Folder
Trim the end position by up to 10mm on a packaging line to fold varying corrugated board thicknesses, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-S with MBLJ40X275-10-S
To replace this MALJ40X275-10-S, order the direct replacement MBLJ40X275-10-S. Confirm the 40mm bore, 275mm stroke, 10mm adjust code, PT G1/4 port, and FA/LB mounting (no back cover or SDB). The -S magnet means your old CS1-M/DS1-M sensors must become CMSG/DMSG/EMSG switches. At 275mm stroke, mind rod side-load bending on the 16mm rod. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ40X275-10-S (same bore/stroke/adjust)
- ✓ Same 265–275 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 MBLJ40X275-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-10-S FAQ
Yes, the MALJ40X275-10-S is discontinued. The direct replacement is the MBLJ40X275-10-S, which matches the 40mm bore, 275mm stroke, 10mm adjust code, and G1/4 port. You must update your sensors: the old CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG switches, and the threaded covers become a riveted rolling-packed body.
The 10mm adjust code provides a usable stroke window of 265-275mm. Remember the adjuster is a travel stop, not a lock; it cannot hold a load without live air.
