This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X160-30-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X160-30-LB 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 MALJ40X160-30-LB
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-LB is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 130 to 160 mm. This model is discontinued — the drop-in replacement is the MBLJ40X160-30-LB.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-LB
The AirTAC MALJ40X160-30-LB is a discontinued double-acting, single-rod adjustable-stroke cylinder. It has a 40mm bore and uses a rear screw to trim the stroke by up to 30mm, giving a usable end-position window of 130-160mm. This 40mm bore outputs 628N push and 528N pull at 0.5MPa, and uses a G1/4 port. The exact drop-in replacement is the MBLJ40X160-30-LB, matching the bore, stroke, adjust code, force, and LB foot mounting.
This unit lacks a magnet (-S) and cannot accept a position sensor. The adjuster acts as a travel stop to fine-tune reach without adding external shims, but it does not hold load without live air. The fixed rubber bumper softens end impact, and the original threaded covers upgrade to a riveted rolling-packed body on the MBLJ. If you need a sensor on the replacement, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family.

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 MBLJ40X160-30-LB carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-LB Is Used
Packaging Carton Erector
Dial in the 130-160mm push depth on a carton erector to fold varying box sizes, using the 628N push force to cleanly break creases without crushing the cardboard.
Palletizing End-Effector
Set the exact 160mm reach on a palletizing gripper to place parts gently, using the rear stop to compensate for tooling variations while the LB mount holds the body rigid.
Bending Press Stopper
Use the 30mm adjustment window to set a precise lower-deck position on a small bending press, relying on the 128kgf max force to hold the form before the return stroke.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-LB with MBLJ40X160-30-LB
To replace this MALJ40X160-30-LB, order the MBLJ40X160-30-LB to retain the 40mm bore, 160mm stroke, 30mm adjust, G1/4 port, PT threads, and LB foot mount. The adjuster sets the 130-160mm end position but is a travel stop, not a lock; use an external lock for held loads. This SKU has no magnet, so it cannot take a sensor; the MBLJ upgrade adds CMSG/DMSG/EMSG sensor compatibility if needed.
For sizing both ways: step down to a 32mm bore (402N push at 0.5MPa, G1/8 port) for lighter fixtures, or step up to a larger standard bore if you need more force. The 40mm bore yields 628N push, 528N pull, 880N push at 0.7MPa, and 128kgf max at 1.0MPa. At 160mm stroke, watch rod-bending and side-load—keep the load guided to avoid binding the 16mm rod.
Upgrade checklist
- ✓ Order the MBLJ40X160-30-LB (same bore/stroke/adjust)
- ✓ Same 130–160 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 MBLJ40X160-30-LB instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-LB FAQ
Yes, the MALJ40X160-30-LB is discontinued. The exact drop-in replacement is the MBLJ40X160-30-LB, which matches the 40mm bore, 160mm stroke, 30mm adjust code, G1/4 port, and LB foot mounting. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The -30 adjust code lets you trim up to 30mm at the rear, creating a usable stroke window of 130-160mm. The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and 128kgf max at 1.0MPa. Note this SKU has no magnet, so it cannot accept a position sensor.
