This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X55U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X55U 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 MAL40X55U (Discontinued) -> MBL40X55U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 55mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X55U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X55U is a discontinued double-acting aluminum mini round cylinder with a 40 mm bore and 55 mm stroke. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. AirTAC replaced this legacy unit with the MBL40X55U, a drop-in alternative that matches the exact bore, stroke, output force, G1/4 port size, and flat-end rear mounting.
This specific SKU features a U flat-end back cover for rigid, non-articulating mounting and lacks a magnet, meaning it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for structural rigidity. Both designs rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X55U 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 MBL40X55U 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). |
| ×55 | 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.
Secures printed circuit board panels against a router bed during depaneling, using the 880 N push force at 0.7 MPa to prevent substrate vibration.
Actuates a short-stroke routing flap on a packaging conveyor, where the 55 mm stroke and flat-end U rear cover provide rigid, stable deflection of light cartons.
Tamps shipping labels onto rigid pallets, using the 628 N force to ensure full adhesive contact without requiring a pivot joint.
To replace the MAL40X55U, order the MBL40X55U. Confirm your 40 mm bore, 55 mm stroke, G1/4 port, PT tapered thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot support a position sensor; if you need position feedback, step up to an MBL40X55US and upgrade to the current CMSG, DMSG, or EMSG switch family (the older CS1-M and DS1-M sensors are obsolete).
If you need to resize, the next size down is the 32 mm bore (delivering 402 N push at 0.5 MPa), and the next size up is the 50 mm profile cylinder. Note that the fixed rubber bumper is not a lock; a plain MAL or MBL cylinder will drift and drop its load when air pressure is lost. If your application requires end-of-stroke deceleration control rather than a basic bumper, specify the MBLC variant for an adjustable air cushion.
Upgrade checklist
Yes, the MAL40X55U is discontinued. The exact drop-in replacement is the MBL40X55U, which offers the same 40 mm bore, 55 mm stroke, 628 N push force, G1/4 port, and U flat-end mounting. The main physical change is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. This specific U-model lacks a magnet, so it cannot use CS1-M or DS1-M sensors.
