This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X55SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X55SCA 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 MAL40X55SCA (Discontinued) -> MBL40X55SCA 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 MBL40X55SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X55SCA is a discontinued double-acting aluminum mini round cylinder delivering 628 N push and 528 N pull at 0.5 MPa. It features a 40 mm bore, a 55 mm stroke, and a G1/4 port. AirTAC replaced this legacy unit with the MBL40X55SCA, a drop-in alternative that matches the original force, port size, and CA pivot mounting exactly.
This SKU includes a built-in magnet (-S) for position detection and a CA pivot back cover that swings on a pin to absorb arcing loads. The original MAL uses threaded front and back covers, whereas the current MBL body uses a riveted rolling-packed construction. Note that the -S magnet on this discontinued model pairs with older CS1-M or DS1-M switches, while the MBL replacement requires the newer CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X55SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X55SCA 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.

Uses the 628 N push force at 0.5 MPa to reliably fold heavy corrugated cardboard flaps on packaging lines, with the CA pivot absorbing any slight misalignment during the stroke.
Pushes small metal stamped parts out of a progressive die area, relying on the 16 mm hard-chrome plated carbon steel rod to withstand repetitive impact forces.
Actuates a mechanical diverter gate to sort incoming pallets, where the 55 mm stroke provides fast redirection and the G1/4 port ensures high flow for rapid cycling.
To replace the MAL40X55SCA, order the MBL40X55SCA and confirm the 40 mm bore, 55 mm stroke, PT thread, G1/4 port, CA pivot back cover, and the -S magnet requirement. Because the -S magnet switches from CS1-M/DS1-M to the CMSG/DMSG/EMSG sensor family on the MBL, you must update your proximity switches during the cylinder swap. If your application needs adjustable end-of-stroke cushioning rather than the fixed rubber bumper found on both the MAL and MBL, step up to the MBLC variant.
When sizing, check the neighboring bores to ensure 40 mm is correct. Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up is not an option since 40 mm is the largest standard MAL mini round size. Keep in mind a plain cylinder does not hold a load if air pressure drops; the rod will drift. For suspended or vertical loads, add an external pilot-operated check valve or a dedicated rod lock.
Upgrade checklist
Yes, the MAL40X55SCA is discontinued. The exact drop-in replacement is the MBL40X55SCA, which shares the same 40 mm bore, 55 mm stroke, G1/4 port, and CA pivot mounting. You must update your sensors because the -S magnet on the MBL works with CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M units.
The 40 mm bore generates a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion.
