This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL40X350SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL40X350-S-U (Discontinued) -> MBL40X350-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 350mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL40X350-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X350-S-U is a discontinued double-acting aluminum mini round cylinder. As the largest bore in this legacy series, it delivers a robust 628 N push force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating. This specific SKU features a built-in magnet (-S) and a U flat-end back cover. Because production has ended, the direct replacement is the MBL40X350-S-U, matching the 40 mm bore, 350 mm stroke, G1/4 port, and output force exactly.
When upgrading to the MBL40X350-S-U, note that the older MAL threaded front and back covers are replaced by a riveted rolling-packed body for equal rigidity. The -S magnet on your legacy cylinder currently pairs with CS1-M or DS1-M reed switches; the MBL replacement transitions to the modern CMSG, DMSG, or EMSG sensor families. The MAL relies on a fixed rubber bumper, whereas the current line offers an adjustable air cushion in the MBLC variant.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X350-S-U 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 MBL40X350-S-U produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 880 N of thrust at 0.7 MPa to unlock and retract heavy mold cores during injection molding cycles, using the 350 mm stroke to fully clear the mold cavity.
Drives a heavy diverter arm on a packaging conveyor, relying on the 40 mm bore's 628 N push force at 0.5 MPa to reliably redirect loaded pallets onto secondary tracks.
Executes the 350 mm opening stroke on a blow molding clamp fixture, where the U flat-end rear cover provides rigid, straight-line mounting to withstand machine vibration.
To replace the MAL40X350-S-U, order the MBL40X350-S-U to retain the 40 mm bore, 350 mm stroke, M12x1.25 rod-end thread, PT port thread, U flat-end back cover, and -S magnet. If 628 N push at 0.5 MPa is excessive, step down to the 32 mm bore (402 N push); if you need more force, this is the largest mini round size available. The -S magnet enables position detection, but prepare to upgrade your legacy CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors. The fixed rubber bumper is not an adjustable cushion; order an MBLC if end-of-stroke deceleration is required. At 350 mm, the 16 mm rod is vulnerable to bending under lateral stress; use an external guide rail or pivot mount. A plain cylinder drifts when air is lost, so add an external rod lock for fail-safe load holding.
Upgrade checklist
Yes, the MAL40X350-S-U is discontinued. The direct replacement is the MBL40X350-S-U, which matches the 40 mm bore, 350 mm stroke, G1/4 port, and mounting. You simply order the MBL equivalent.
The full figure set for this 40 mm bore cylinder is: 628 N push at 0.5 MPa, 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. The -S magnet allows position sensing with older CS1-M or DS1-M switches; the MBL replacement requires CMSG, DMSG, or EMSG sensors.
