This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X350-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X350-100 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).

The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X350-100 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 250 to 350 mm. This model is discontinued — the drop-in replacement is the MBLJ40X350-100.
The AirTAC MALJ40X350-100 is a discontinued double-acting single-rod mini cylinder with a 40 mm bore and a 350 mm stroke. It features a rear travel stop that lets you trim up to 100 mm, creating a usable end-position window of 250-350 mm. At 0.5 MPa it delivers 628 N push and 528 N pull force. The exact drop-in replacement is the MBLJ40X350-100, which matches the bore, stroke, G1/4 port and mounting footprint.
This SKU has no magnet and cannot accept a position sensor. Upgrading to the MBLJ changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG if a sensor is later needed, and upgrades the threaded covers to a riveted rolling-packed body. The fixed rubber bumper softens end impact, but the adjuster is a travel stop, not a lock, so it cannot hold a load without live air. On a 350 mm stroke, prevent rod bending by guiding the load to avoid side-load stress.

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 MBLJ40X350-100 carries the same ratings.

Single-rod force, same as a standard MAL of this bore. The MBLJ40X350-100 matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Dial the stroke window from 250-350 mm to act as a depth stop for pallets, using the 628 N push force to halt heavy workpieces without adding external stop blocks.
Fine-tune the mould open height by trimming the rear screw up to 100 mm, synchronizing the 880 N push at 0.7 MPa to the exact plastic sheet thickness.
Set the end position to press edge banding materials, using the fixed rubber bumper to soften the impact at the end of the 350 mm travel without needing an air cushion.
To replace this MALJ40X350-100, order the exact drop-in MBLJ40X350-100. Confirm the 40 mm bore, 350 mm stroke, 100 mm adjust code, PT G1/4 port, M12x1.25 rod thread and FA/LB mounting. This SKU lacks a magnet and cannot take a sensor; if you need sensing, the MBLJ equivalent requires CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock. Because the 350 mm stroke is long, ensure your guidance system prevents side-load rod bending.
For sizing both ways, the next size down is the 32 mm bore, giving 402 N push and 346 N pull at 0.5 MPa. The 40 mm bore is the largest in this family, so there is no larger standard size available.
Upgrade checklist
Yes, the MALJ40X350-100 is discontinued. The exact drop-in replacement is the MBLJ40X350-100, matching the 40 mm bore, 350 mm stroke, 100 mm adjust code, force and G1/4 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The 100 mm adjuster creates a usable stroke window of 250-350 mm. The adjuster is a travel stop, not a lock. Force figures for the 40 mm bore are: 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. This SKU has no magnet and cannot take a sensor.
