This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X240SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X240SCA 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).
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 240mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X240SCA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA
The AirTAC MAL20X240SCA is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 240mm stroke. It delivers 157N of push force and 132N of pull force at 0.5 MPa, utilizing a G1/8 port and an M8x1.25 rod-end thread. AirTAC replaced this legacy unit with the MBL20X240SCA, a true drop-in replacement retaining the exact same bore, stroke, output force, port size, and CA pivot mounting.
This specific SKU includes a built-in magnet (-S) for position sensing; the older MAL works with CS1-M or DS1-M switches, while the modern MBL replacement requires CMSG, DMSG, or EMSG sensors. A key structural upgrade occurred in the body design: the legacy MAL features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body for equally rigid containment. Both generations rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X240SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The MBL20X240SCA 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.

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA Is Used
Textile Loom Let-off
Drives the let-off mechanism on compact textile looms, using the 157N push force at 0.5 MPa to maintain tension on yarn beams within tight frame clearances.
PCB Deflection Gate
Actuates a small deflection gate on a printed circuit board conveyor, relying on the CA pivot to absorb minor angular misalignment during high-speed routing.
Pharma Carton Flap
Folds minor carton flaps on a pharmaceutical packaging line, where the 240mm stroke provides the necessary reach and the self-lubricating bearing prevents grease contamination.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA with MBL20X240SCA
To replace the MAL20X240SCA, order the MBL20X240SCA. Verify your existing setup matches the G1/8 port, the PT tapered thread form, and the CA pivot back cover, which swings on a pin to accommodate arcing loads. Because this SKU includes the -S magnet, remember that your legacy CS1-M or DS1-M switches will not fit the MBL; you must upgrade to CMSG, DMSG, or EMSG sensors.
For sizing flexibility, stepping down to the bore 20 neighbor is not applicable as this is the smallest available size, but stepping up to the 25mm bore will increase your push force to 245N at 0.5 MPa. At 240mm of stroke, the 8mm rod is highly susceptible to bending under side loads; ensure an external guide rail supports the load. Note that the fixed rubber bumper softens impact but does not lock the rod—air loss causes drift, so use an external rod lock for position holding. If your application requires adjustable end-cushioning, step up to the MBLC variant on the current line.
Upgrade checklist
- ✓ Order the MBL20X240SCA (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL20X240SCA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X240SCA FAQ
Yes, the MAL20X240SCA is discontinued. The exact drop-in replacement is the MBL20X240SCA, which matches the 20mm bore, 240mm stroke, G1/8 port, CA pivot back cover, and output force. You must update your sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
At 0.5 MPa, the push force is 157N and the pull force is 132N. At 0.7 MPa, the push force is 220N. The maximum theoretical force is 32 kgf at 1.0 MPa. It features an 8mm rod, an M8x1.25 rod-end thread, and operates at speeds between 30-800 mm/s.
