This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X45CA, 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 MAL20X45CA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X45CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 45mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X45CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X45CA
The AirTAC MAL20X45CA is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 45mm stroke. As a compact unit, it delivers 157N of push force and 132N of pull force at 0.5 MPa. It features a CA pivot back cover designed to swing on a pin for arcing loads. Because this legacy series is end-of-life, you should order the direct replacement: the MBL20X45CA.
The MBL20X45CA shares the exact same bore, stroke, output force, G1/8 port, and CA mounting. The original MAL utilized threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body. Additionally, this specific MAL20X45CA lacks a magnet, meaning it cannot accept any position sensor. If you ever need sensing on the replacement, you must specify an -S code on the MBL, which updates the sensor family from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG switches.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X45CA 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 MAL20X45CA Is Used
Textile Loom Guide
Actuates a thread guide arm on a compact weaving loom, using the 157N push force and CA pivot bracket to smoothly accommodate the mechanism's arcing motion.
PCB Edge Conveyor
Pushes a small stopper pin on an electronics assembly line conveyor, fitting easily into tight machine bays thanks to the 20mm aluminum body.
Vial Sorting Divert
Swings a small deflector gate on a pharmaceutical vial sorting track, where the CA clevis absorbs side-to-side swing without binding the 8mm rod.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X45CA with MBL20X45CA
To replace the MAL20X45CA, order the MBL20X45CA, ensuring you keep the PT thread and CA pivot back cover. If your application requires an adjustable air cushion to soften end-of-stroke impacts, note that the MAL only had a fixed rubber bumper; you will need to upgrade to the MBLC version on the current line. If sizing up or down, the next size up is the 25mm bore (245N push at 0.5 MPa), and the 20mm is the smallest available bore in this series. Because this is a double-acting cylinder, a plain MBL does not hold its load when air pressure is lost; the rod will drift. For safety, add an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL20X45CA (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 MBL20X45CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X45CA FAQ
Yes, the MAL20X45CA is discontinued. The direct replacement is the MBL20X45CA, which matches the 20mm bore, 45mm stroke, G1/8 port, and CA pivot mounting. The MBL uses a riveted body instead of threaded covers, but the performance is identical.
At 0.5 MPa, the push force is 157N and pull is 132N. At 0.7 MPa, push is 220N, with a maximum theoretical force of 32 kgf at 1.0 MPa. It has a fixed rubber bumper, not an adjustable cushion, and it cannot hold a load if air pressure drops.
