This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X330CA, 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 MAL20X330CA
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X330CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 330mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X330CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X330CA
The AirTAC MAL20X330CA is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 330mm stroke. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The direct replacement is the MBL20X330CA, which matches the original bore, stroke, force, G1/8 port, and CA mounting. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This specific CA back cover configuration incorporates a pivot clevis that swings on a pin, making it ideal for arcing loads rather than rigid mounting. Because this SKU lacks the -S magnet, it cannot accommodate a position sensor. Internally, a heterogeneous two-way seal retains grease, and the 8mm carbon-steel rod features 20 um hard-chrome plating for wear resistance. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X330CA 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 MAL20X330CA Is Used
Textile Loom Guide
Drives a 330mm yarn guide arm on a weaving loom, where the CA pivot absorbs the mechanism's arcing motion and the 157 N push force at 0.5 MPa shifts the lightweight carrier.
Package Diverter Arm
Actuates a 330mm routing flap on a compact packaging conveyor, using the fixed rubber bumper to soften the end-of-stroke impact without needing external shock absorbers.
Bin Pick-and-Place
Extends a small vacuum gripper 330mm into a dense parts bin, relying on the self-lubricating front-cover bearing guide to maintain smooth travel despite the long 8mm rod extension.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X330CA with MBL20X330CA
To replace the MAL20X330CA, order the MBL20X330CA. Verify your 8mm rod-end thread (M8x1.25) and the PT port thread form. The CA pivot back cover is retained directly on the MBL. Because this unit has no -S magnet, you cannot mount a position switch; if you need sensing, order an MBL20X330SCA and upgrade to the modern CMSG, DMSG, or EMSG sensors, as the older CS1-M/DS1-M switches are obsolete. If your load requires adjustable end-cushioning, step up to the MBLC variant, as the MAL only offered a fixed rubber bumper.
For sizing flexibility, stepping down to the 12mm bore class reduces your force significantly, while stepping up to the 25mm bore yields 245 N push at 0.5 MPa. At 330mm of stroke, the 8mm rod has low side-load tolerance; you must use the CA pivot to absorb arcing moments or add an external guide rail to prevent rod bending. Note that a plain MBL does not hold its position or load when air is lost—the rod drifts. For load holding, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL20X330CA (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 MBL20X330CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X330CA FAQ
Yes, the MAL20X330CA is discontinued. The direct replacement is the MBL20X330CA, which offers the same 20mm bore, 330mm stroke, CA pivot mounting, and G1/8 port. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
At 0.5 MPa, it pushes with 157 N and pulls with 132 N. At 0.7 MPa, push force is 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot take a position sensor; sensing requires the -S variant and the newer CMSG/DMSG/EMSG switches.
