This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-75 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 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 drop-in 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 exact drop-in 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. It delivers 628N push and 528N pull at 0.5 MPa.
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)

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75 Is Used
Circuit Breaker Actuation
Dialing the 100-175mm window precisely sets the mechanical throw for circuit breaker mechanism testing, using the 880N push at 0.7 MPa to reliably latch and trip heavy switchgear contacts.
Pallet Notch Positioning
Adjusts the end stop for a pallet routing station, tuning the 40mm bore's 628N force to press notching blades to an exact depth without installing external physical stops on the machine bed.
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.
For sizing, step down to the 32mm bore (402N push at 0.5 MPa) if your load is lighter, or step up to a larger ISO 15552 cylinder if you need more force than the 128kgf maximum of this 40mm frame. 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.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75 FAQ
Yes, the MALJ40X175-75 is discontinued. The exact drop-in replacement is the MBLJ40X175-75, which matches the 40mm bore, 175mm stroke, -75 adjust code, 628N push at 0.5 MPa, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 40mm bore provides 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum 128kgf at 1.0 MPa. The -75 adjust code lets you trim up to 75mm at the rear, creating a usable stroke window from 100 to 175mm. Note that this adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.
