This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X55CA, 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 MAL20X55CA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X55CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 55mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X55CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X55CA
The AirTAC MAL20X55CA is a discontinued compact double-acting aluminum mini round cylinder. Delivering 157 N of push force and 132 N of pull force at 0.5 MPa, it uses a G1/8 port and an Ø8 mm carbon-steel rod with 20 um hard-chrome plating. Because this legacy series has ended production, AirTAC provides the MBL20X55CA as the direct replacement. The MBL successor matches the 20 mm bore, 55 mm stroke, output force, port size, and CA pivot mounting, ensuring a seamless physical retrofit.
Two distinct engineering details define this SKU. First, the CA back cover is a pivot clevis designed to swing on a pin, making it ideal for mechanisms with arcing travel rather than rigid linear constraints. Second, because this specific code lacks the -S suffix, it has no internal magnet and cannot accept a position sensor; furthermore, the original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for faster assembly.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X55CA 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 MAL20X55CA Is Used
Textile Loom Guide
Actuates a lightweight thread guide on a textile loom, where the 157 N push force at 0.5 MPa is sufficient for shifting yarn paths and the compact aluminum body fits tight machine frames.
PCB Shuttle Pivot
Pivots a small PCB shuttle using its CA clevis, accommodating the slight arcing motion of the transfer arm while cycling 55 mm to move light electronic boards.
Bottle Deflector Arm
Extends 55 mm to push small plastic bottles on a packaging conveyor, utilizing the self-lubricating front-cover bearing to maintain smooth operation without external grease lines.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X55CA with MBL20X55CA
To replace the MAL20X55CA, order the MBL20X55CA. Verify your existing hardware matches the default PT tapered thread and the CA pivot back cover. Since this SKU lacks a magnet, you cannot mount a sensor; if you need position detection, upgrade to an MBL20X55SCA and note that the modern MBL uses CMSG, DMSG, or EMSG switches instead of the legacy CS1-M/DS1-M family. If you need an adjustable air cushion to soften end-of-stroke impacts—which the fixed rubber bumper on this MAL cannot provide—select the MBLC variant on the current line.
For sizing flexibility, the next size down is the 12 mm bore (if available in your series) or you can step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. A plain MBL cylinder does not hold its load when air pressure drops; the rod will drift. For safety under suspended loads, install an external rod lock or a pilot-operated check valve. At 55 mm stroke, side-load risk is minimal, but the small Ø8 mm rod still demands careful alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBL20X55CA (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 MBL20X55CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X55CA FAQ
Yes, the MAL20X55CA is discontinued. The direct replacement is the MBL20X55CA, which matches the 20 mm bore, 55 mm stroke, 157 N push force, G1/8 port, and CA pivot mounting.
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa it provides 220 N push, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this SKU lacks the -S magnet suffix, it cannot accept a position sensor.
