This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X70CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X70CA 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 MAL40X70CA (Discontinued) -> MBL40X70CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 70mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X70CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X70CA is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the MAL family, it delivers a robust 628 N push and 528 N pull at 0.5 MPa, utilizing a G1/4 port and a Ø16 mm carbon-steel rod with 20 µm hard chrome plating. Because this legacy unit is end-of-life, you should order the exact drop-in replacement: the MBL40X70CA. It matches the 40 mm bore, 70 mm stroke, output force, port size, and CA pivot mounting perfectly.
This specific SKU features a CA pivot back cover, designed to swing on a pin to absorb arcing loads, and uses the default PT tapered thread. Note that this cylinder lacks a built-in magnet (-S), meaning it cannot support a position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both rely on a fixed rubber bumper for end-of-stroke damping; if your application requires an adjustable air cushion, you must step up to the current MBLC line.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X70CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X70CA 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.

Drives 628 N of push force at 0.5 MPa to knock thermoplastic parts off injection mold cores, where the CA pivot absorbs the angular misalignment of the stripper plate.
Actuates a 70 mm stroke divert flap on a packaging conveyor, using the robust 40 mm bore to overcome the friction of cardboard cartons sliding on the belt.
Applies downward clamping pressure on a bed-of-nails printed circuit board tester, where the fixed rubber bumper prevents shock damage to the test pins.
To replace the MAL40X70CA, order the MBL40X70CA. Confirm your 40 mm bore, 70 mm stroke, G1/4 port, and PT thread form. The CA back cover is a pivot clevis that swings on a pin, which is critical if your mechanism generates arcing or side loads. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, you must switch to an MBL40X70SCA and upgrade to the modern CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete.
For sizing flexibility, the next size down is the 32 mm bore, which yields 402 N push and 346 N pull at 0.5 MPa. If you need more force, there is no larger MAL bore, but you would step out of this mini round family entirely. Remember that a plain MAL or MBL does not hold its load when air is lost; the rod drifts and the bumper only softens the stroke end. For vertical loads, add an external rod lock or a pilot-operated check valve. If your machine needs adjustable cushioning rather than a fixed rubber bumper, specify the MBLC40X70CA instead.
Upgrade checklist
Yes, the MAL40X70CA is discontinued. The exact drop-in replacement is the MBL40X70CA. It matches the 40 mm bore, 70 mm stroke, G1/4 port, and CA pivot mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the 40 mm bore provides 628 N push and 528 N pull. 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 an -S magnet, it cannot accept a position sensor; you would need the MBL40X70SCA and CMSG/DMSG/EMSG switches for detection.
