This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X175-75, 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 MALJ40X175-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 100 to 175 mm. This model is discontinued — the direct replacement is the MBLJ40X175-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75
The AirTAC MALJ40X175-75 is a discontinued double-acting mini cylinder with a 40mm bore and a 175mm stroke. It is discontinued; the direct replacement is the MBLJ40X175-75. The -75 code means the rear adjuster lets you trim up to 75mm of travel, creating a usable end-position window from 100 to 175mm without external stops.
This bore uses a G1/4 port and a Ø16mm carbon-steel rod with a 20um hard chrome plating. The original MALJ features threaded covers and a fixed rubber bumper, while the MBLJ upgrade shifts to a riveted rolling-packed body. This specific SKU lacks the -S magnet, meaning it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.

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 MBLJ40X175-75 carries the same ratings.
Theoretical Output Force (Ø40mm)

| 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 MBLJ40X175-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75 Is Used
Sheet Metal Bender Backgauge
Fine-tunes the backgauge reach on a small sheet metal bender, trimming up to 75mm of stroke to accommodate different flange lengths while the fixed rubber bumper softens the impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75 with MBLJ40X175-75
To replace the MALJ40X175-75, order the MBLJ40X175-75. Confirm the 40mm bore, 175mm stroke, -75 adjust code, G1/4 port, and PT thread form. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor; if you upgrade to an MBLJ with an -S suffix, the sensor family changes from the older CS1-M/DS1-M to the newer CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock.
At 175mm stroke, minimize side-loading to prevent rod-bending and premature seal wear; keep the load guided.
Upgrade checklist
- ✓ Order the MBLJ40X175-75 (same bore/stroke/adjust)
- ✓ Same 100–175 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 MBLJ40X175-75 instead of this discontinued model.
