This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X620SCA, 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 MAL20X620SCA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X620SCA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 620mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X620SCA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X620SCA
The AirTAC MAL20X620SCA is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and a 620mm non-standard, made-to-order stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa. AirTAC replaced this legacy unit with the MBL20X620SCA, a direct alternative retaining the exact bore, stroke, port size, and CA pivot mounting. The 620mm length exceeds the 500mm standard catalog maximum, meaning it was engineered as a special order for deep-reach applications.
This SKU features a built-in -S magnet for position detection. On the MAL, this magnet interfaces with older CS1-M and DS1-M reed switches, whereas the MBL replacement transitions to modern CMSG, DMSG, and EMSG solid-state sensors. Additionally, the MAL employs threaded front and back covers on its barrel, while the MBL utilizes a riveted rolling-packed body. Both designs share a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X620SCA 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 MAL20X620SCA Is Used
Textile Yarn Guide
Moves a yarn guide carriage across a 620mm loom width; the 157N push force at 0.5MPa easily overcomes guide friction while the CA pivot absorbs carriage sway.
Package Diverter Arm
Actuates a long diverter arm over a packaging conveyor, utilizing the 620mm stroke to reach across multiple product lanes without needing a larger bore.
Cold Storage Pusher
Ejects frozen food cartons from a blast freezer shelf; the self-lubricating front-cover bearing guide ensures smooth motion despite temperature fluctuations.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X620SCA with MBL20X620SCA
To replace the MAL20X620SCA, order the MBL20X620SCA, ensuring you match the G1/8 port, M8x1.25 rod-end thread, CA pivot back cover, and PT thread form. Because this is a 620mm stroke on a small 8mm rod, side-load tolerance is extremely low; you must use an external guide rail to prevent rod bending and premature seal wear. The CA pivot clevis is essential here to absorb arcing loads during the long travel. If you need adjustable cushioning for heavy loads at the end of this long stroke, step up to the MBLC20X620SCA on the current line, as the MAL only offers a fixed rubber bumper. For sizing flexibility, stepping down is not an option below 20mm, but stepping up to the 32mm bore yields 402N of push force at 0.5MPa if you need more power. Note that a plain MBL does not hold its load when air is lost; the rod drifts, so add an external rod lock or pilot-operated check valve for vertical safety.
Upgrade checklist
- ✓ Order the MBL20X620SCA (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 MBL20X620SCA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X620SCA FAQ
Yes, the MAL20X620SCA is discontinued. The direct replacement is the MBL20X620SCA, which matches the 20mm bore, 620mm stroke, CA pivot mounting, G1/8 port, and force output. You must update your sensors, as the MAL -S magnet uses CS1-M/DS1-M switches while the MBL uses CMSG/DMSG/EMSG switches.
The 20mm bore double-acting cylinder provides 157N push and 132N pull at 0.5MPa, 220N push at 0.7MPa, and a maximum theoretical force of 32kgf at 1.0MPa. It operates at 30-800mm/s with a fixed rubber bumper.
