This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X270CALB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X270CALB 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 MAL40X270CALB (Discontinued) -> MBL40X270CALB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 270mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X270CALB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X270CALB is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it features a 40 mm bore, a 270 mm stroke, and a G1/4 port. The exact drop-in replacement is the MBL40X270CALB, which matches the original bore, stroke, output force, port size, and LB foot mounting. The legacy MAL body utilized threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body for equally robust performance.
This specific SKU includes a CA pivot back cover and an LB foot mounting bracket. Because this configuration lacks the -S magnet option, it cannot accommodate a position sensor. The piston relies on a heterogeneous two-way seal that retains grease, operating alongside a self-lubricating front-cover bearing guide and a carbon-steel rod with 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X270CALB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X270CALB 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.

Leverages the 628 N push force at 0.5 MPa to actuate a mechanical linkage, while the CA clevis back cover accommodates the pivoting arc of the assembly.
Uses the 270 mm stroke to extend a routing flap across a packaging line, relying on the LB foot bracket to secure the body against shifting loads.
Deploys a rigid stop block to halt incoming pallets, absorbing kinetic energy with the fixed rubber bumper at the end of the 40 mm bore extension.
To replace this discontinued cylinder, order the MBL40X270CALB. Verify your setup matches the 40 mm bore, 270 mm stroke, G1/4 port, and PT tapered thread form. This unit pairs an LB foot mount with a CA pivot back cover, allowing the cylinder to swing on a pin to absorb arcing loads. Because this SKU has no -S magnet, it cannot support position sensing; if you require detection, step up to an MBL model with the S suffix and note that the MBL uses modern CMSG, DMSG, or EMSG switches instead of the older CS1-M / DS1-M sensors.
If you need to adjust your force output, stepping down to a 32 mm bore yields 402 N of push force at 0.5 MPa, while no larger standard MAL mini round bore exists. At 270 mm of stroke, the 16 mm rod is susceptible to bending under lateral stress; use the CA pivot to align the load path or add an external guide. The fixed rubber bumper softens end-of-stroke impacts but does not lock the rod—air loss will cause drift. For adjustable air cushioning, switch to the current MBLC series.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X270CALB, which offers the same 40 mm bore, 270 mm stroke, G1/4 port, LB foot mount, and CA pivot back cover. The newer MBL body uses a riveted rolling-packed design instead of the original threaded covers.
At 0.5 MPa, it provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force is 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot support a position sensor.
