This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X40U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
The AirTAC AirTAC MAL40X40U (Discontinued) → MBL40X40U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 40mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X40U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X40U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 40mm stroke. It delivers 628N push and 528N pull force at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X40U, which matches the original force, port size, and flat-end rear cover for a seamless machine retrofit.
This legacy U-coded SKU features a rigid flat-end back cover for straight inline mounting. Because this specific model lacks the -S magnet option, it cannot accept a position sensor. The original MAL body relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both designs use a fixed rubber bumper rather than an adjustable cushion, and the carbon-steel rod is protected by 20um hard-chrome plating within a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X40U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X40U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×40 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBL uses CMSG/DMSG/EMSG). |
| CA / U / CM | Back cover: CA pivot, U flat-end or CM round-end. |
Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 628N of push force at 0.5 MPa to knock small stamped metal parts out of a progressive die on a compact packaging line.
Uses the 40mm stroke to tuck inner corrugated flaps prior to tape sealing, fitting easily into tight conveyor side-guides.
Actuates a routing flap on a 24V DC roller conveyor, relying on the rigid U flat-end cover to maintain alignment under lateral flow.
To replace the discontinued MAL40X40U, order the MBL40X40U. Verify that your plumbing matches the G1/4 port and the PT tapered thread form. The U back cover provides a rigid flat mounting surface; if your application requires a pivoting rear joint, step up to a CA clevis model instead. If you need to detect rod position, this non-magnet SKU cannot accept a sensor, so you must select an MBL40X40US and migrate to the current CMSG / DMSG / EMSG switch family (the older MAL used CS1-M / DS1-M sensors).
For sizing flexibility, step down to the 32mm bore if 402N of push force at 0.5 MPa is sufficient, or step up to a larger profile cylinder if you exceed the 128kgf maximum theoretical limit. Note that the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if air pressure drops, the load will drift. If your application requires end-of-stroke deceleration tuning, upgrade to the current MBLC line which offers adjustable air cushions.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X40U. It provides the same 40mm bore, 40mm stroke, 628N push force, G1/4 port, and rigid U flat-end mounting. The main upgrade is a riveted rolling-packed body replacing the original threaded covers.
At 0.5 MPa it delivers 628N push and 528N pull; at 0.7 MPa it delivers 880N push, with a theoretical maximum of 128kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
