This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X40CA, 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).
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X40CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA
The AirTAC MAL20X40CA is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 40mm stroke. It delivers 157N of push force and 132N of pull force at 0.5 MPa, making it suitable for light-duty cycles. Because this legacy series is end-of-life, you should order the direct replacement: the MBL20X40CA. The MBL shares the same bore, stroke, output force, G1/8 port, and CA mounting, so it fits the same application without mechanical changes.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing loads, distinguishing it from rigid flat-end models. Inside, the piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide. The 8mm carbon-steel rod is plated with 20um hard chrome for wear resistance. Because this unit lacks the -S magnet code, it cannot accept a position sensor. Note that the MAL used threaded front and back covers, whereas the current MBL body uses a riveted rolling-packed construction; both share identical ratings.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X40CA 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 | — |

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA Is Used
PCB Component Insertion
Pushing small electronic connectors onto circuit boards using the 157N push force at 0.5 MPa, where the short 40mm stroke fits tight machinery.
Package Diverter Arm
Actuating a lightweight swing gate on a packaging line, taking advantage of the CA pivot cover that naturally handles arcing motion.
Small Parts Ejector
Ejecting plastic moldings from a tight fixture, relying on the 8mm hard-chrome plated rod to resist wear during rapid cycling.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA with MBL20X40CA
To replace the MAL20X40CA, order the MBL20X40CA. Confirm your 20mm bore, 40mm stroke, PT thread, and CA pivot back cover are correct. If you need to adjust force, stepping down is not an option as 20mm is the smallest available bore. Stepping up to the 32mm bore yields 402N of push force at 0.5 MPa, which is a significant jump in power.
If your machine requires end-of-stroke cushioning beyond the fixed rubber bumper found on this MAL, you must look at the current MBLC line for an adjustable air cushion. Because this SKU lacks the -S magnet, it cannot support position sensing; if you need a sensor, order the MBL20X40SCA and note that the switch family changes from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG. Finally, a plain bumper is not a lock—the rod will drift if air pressure is lost, so use an external rod lock for suspended loads.
Upgrade checklist
- ✓ Order the MBL20X40CA (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 MBL20X40CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X40CA FAQ
Yes, the MAL20X40CA is discontinued. The direct replacement is the MBL20X40CA, which matches the 20mm bore, 40mm stroke, 157N push force, G1/8 port, and CA pivot mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
At 0.5 MPa, the 20mm bore provides 157N push and 132N pull force. At 0.7 MPa it provides 220N push, with a theoretical maximum of 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor; you would need the S variant and legacy CS1-M / DS1-M switches.
