This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-50-S 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 MALJ40X100-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 50 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-50-S.
The AirTAC MALJ40X100-50-S is a discontinued double-acting, single-rod mini cylinder with a rear adjustable stroke stopper. It delivers 628 N push and 528 N pull force at 0.5 MPa (880 N push at 0.7 MPa, 128 kgf max). The -50 adjust code lets you trim the rear travel by up to 50 mm, creating a usable end-position window from 50 to 100 mm without adding external stops.
The exact drop-in replacement is the MBLJ40X100-50-S, matching the 40 mm bore, 100 mm stroke, G1/4 port, and mounting footprint. Upgrading changes the construction from threaded covers to a riveted rolling-packed body. The -S magnet also shifts sensor families: the legacy MALJ uses CS1-M / DS1-M switches, while the MBLJ uses CMSG / DMSG / EMSG. Remember the adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ40X100-50-S carries the same ratings.
| Pressure | Push force | Pull force |

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X100-50-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×100 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 50–100 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Dial in the 50-100 mm push stroke to deflect heavy pallets onto a packaging branch, utilizing the 628 N push force at 0.5 MPa to move loaded carts reliably.
Set a precise 65 mm end position to lower a test probe nest onto circuit boards without crushing the substrate, using the rear stopper for exact depth control.
Adjust the retract window to position a sheet-metal bending anvil at varied distances from the clamp, taking advantage of the 528 N pull force for rigid tool holding.
To replace this MALJ40X100-50-S with the MBLJ40X100-50-S, confirm the 40 mm bore, 100 mm stroke, and the -50 adjust code (yielding a 50-100 mm window). Verify your port is G1/4 with an M12x1.25 rod-end thread, and check your mounting hardware is FA or LB, as this series uses no back cover or SDB. Update your sensor inventory: the -S magnet requires moving from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
When sizing, you can step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up to a larger ISO 15552 profile cylinder if your frame allows. The fixed rubber bumper softens end impact but is not an adjustable air cushion. Because the adjuster is a stop and not a lock, any application requiring held load during air loss needs an external pneumatic lock.
Upgrade checklist
Yes, the MALJ40X100-50-S is discontinued. The exact drop-in replacement is the MBLJ40X100-50-S, which matches the 40 mm bore, 100 mm stroke, 50 mm adjust code, G1/4 port, and force. You will need to update your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG switches for the new riveted body.
The force ratings 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. The -50 adjust code lets you trim the rear travel by up to 50 mm, giving a usable stroke window from 50 to 100 mm. The adjuster is a travel stop, not a lock, so it will not hold a load without live air.
