This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X140SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X140SCA 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 MAL20X140SCA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140SCA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 140mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X140SCA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140SCA
The AirTAC MAL20X140SCA is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 140mm stroke. It delivers 157N of push force at 0.5MPa. The exact drop-in replacement is the MBL20X140SCA, matching the bore, stroke, output force, G1/8 port, and CA pivot mounting. The legacy MAL body uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This SKU includes a built-in magnet (-S) and a CA pivot back cover. The magnet on the MAL functions with older CS1-M or DS1-M reed switches, but buyers upgrading to the MBL must switch to the current CMSG, DMSG, or EMSG sensor families. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod has 20um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X140SCA 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 MBL20X140SCA 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 MAL20X140SCA Is Used
PCB routing arm
Drives a routing arm on a printed circuit board loader, using the 157N push force at 0.5MPa to push panels into the test fixture.
Carton flap folder
Pivots a small mechanical arm to fold minor flaps on small pharmaceutical cartons, where the CA clevis accommodates the swing arc.
Vial sorting gate
Actuates a diverter gate on a lab vial sorting line, benefiting from the compact 20mm body to fit between tight conveyor lanes.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140SCA with MBL20X140SCA
To replace this MAL20X140SCA, order the MBL20X140SCA. Confirm the 140mm stroke, PT thread form, G1/8 port, and the CA pivot clevis, which allows the cylinder to swing on a pin to absorb arcing loads. Because the -S magnet is present, plan to upgrade your CS1-M or DS1-M switches to CMSG or DMSG sensors. If your application requires an adjustable air cushion rather than the standard fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 16mm bore is not an option in this mini series, but stepping up to the 25mm bore yields 245N of push force at 0.5MPa if you need more power. At 140mm of stroke, the 8mm rod has low side-load tolerance; ensure the CA pivot moves freely or add an external guide to prevent rod bending. Note that this cylinder does not hold its position when air is lost—the bumper only softens the end of stroke, so use a rod lock for suspended loads.
Upgrade checklist
- ✓ Order the MBL20X140SCA (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 MBL20X140SCA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140SCA FAQ
Yes, the MAL20X140SCA is discontinued. The exact drop-in replacement is the MBL20X140SCA, which shares the same 20mm bore, 140mm stroke, G1/8 port, and CA pivot mounting. The MBL uses a riveted rolling-packed body instead of threaded covers, and the -S magnet requires upgrading from CS1-M/DS1-M switches to the CMSG/DMSG/EMSG sensor family.
At 0.5MPa, the push force is 157N and the pull force is 132N. At 0.7MPa, the push force increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa. The cylinder operates at 0.1-1.0MPa with a speed range of 30-800mm/s.
