This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X70CA, 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 MAL20X70CA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X70CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 70mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X70CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X70CA
The AirTAC MAL20X70CA is a discontinued compact double-acting aluminum mini round cylinder. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, utilizing an 8 mm carbon-steel rod with 20 um hard chrome plating. Because this legacy unit is end-of-life, AirTAC replaced it with the MBL20X70CA, a direct alternative retaining the exact 20 mm bore, 70 mm stroke, G1/8 port, and CA pivot mounting.
This specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing loads, contrasting with rigid flat-end designs. Unlike the older MAL which uses threaded front and back covers on the barrel, the MBL replacement features a riveted rolling-packed body for equivalent structural integrity. Note that this unit lacks a magnet (-S), so it cannot accept a position sensor; if sensing is needed, the MBL replacement requires an -S designation and uses CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M sensors.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X70CA 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 MBL20X70CA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X70CA Is Used
PCB Depaneling Router
Actuates a cutting blade in a compact electronics assembly cell, using the 157 N push force at 0.5 MPa to cleanly separate individual printed circuit boards.
Pouch Diverter Arm
Swings a lightweight sorting flap on a packaging line conveyor, leveraging the CA pivot back cover to absorb arcing loads during rapid product redirection.
Small Parts Ejector
Pushes tiny plastic moldings out of a machining zone into a bin, relying on the self-lubricating front-cover bearing guide to maintain smooth operation without external grease.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X70CA with MBL20X70CA
To replace the MAL20X70CA, order the MBL20X70CA, confirming the 70 mm stroke, G1/8 port, and default PT thread. The CA pivot back cover must be retained to handle arcing loads. If your application requires position sensing, you must upgrade to an MBL20X70SCA and switch to the current CMSG, DMSG, or EMSG sensor family, as this non-S legacy SKU cannot accept a sensor. If you need an adjustable air cushion instead of the standard fixed rubber bumper, specify the MBLC20X70CA on the current line.
For sizing flexibility, stepping down to the 32 mm bore is not applicable here as 20 mm is the smallest available; however, stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa if your load demands more power. A plain MBL does not hold its position or load when air is lost, as the bumper only softens the end of stroke and is not a lock, so add an external rod lock or pilot-operated check valve for holding requirements. Since the 70 mm stroke is below 300 mm, side-load bending on the 8 mm rod is minimal, but the small rod inherently means low side-load tolerance.
Upgrade checklist
- ✓ Order the MBL20X70CA (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 MBL20X70CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X70CA FAQ
Yes, the MAL20X70CA is discontinued. The direct replacement is the MBL20X70CA, which matches the 20 mm bore, 70 mm stroke, G1/8 port, and CA pivot mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this SKU lacks an -S magnet, it cannot take a position sensor.
