This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X15UH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X15UH in place of this model. 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 MAL20X15UH
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X15UH is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 15mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X15UH, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X15UH
The AirTAC MAL20X15UH is a discontinued, double-acting compact aluminum mini round cylinder with a 20mm bore and 15mm stroke. It delivers 157N of push force and 132N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL20X15UH, which matches the original bore, stroke, output force, G1/8 port, and U flat-end mounting.
This legacy SKU features a U flat-end back cover for rigid rear mounting and uses a PT tapered port thread. Because this specific model lacks the -S magnet code, it cannot accept a position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equivalent durability. Both utilize 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 MBL20X15UH 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 MBL20X15UH produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X15UH Is Used
PCB Component Placement
Using its 157N push force at 0.5 MPa, this 15mm stroke cylinder precisely seats electronic connectors onto printed circuit boards within tight machine envelopes.
Micro-Valve Actuation
The compact 20mm aluminum body and 8mm carbon-steel rod provide rapid, responsive switching for small pneumatic manifold valve clusters in lab automation.
Small Carton Flap Folding
Ideal for packaging lines, the rigid U flat-end mounting stabilizes the cylinder while it folds lightweight cardboard flaps on miniature parcel sealing machines.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X15UH with MBL20X15UH
To replace the discontinued MAL20X15UH, order the drop-in MBL20X15UH. Verify your 20mm bore, 15mm stroke, PT port thread, and the U flat-end back cover. Since this unit has no -S magnet, it cannot support a position sensor; if you ever require position feedback, you must upgrade to an MBL20X15S model and switch to the current CMSG, DMSG, or EMSG sensor family, as the older CS1-M and DS1-M switches are obsolete.
For sizing flexibility, stepping down is not possible as 20mm is the smallest available bore. Stepping up to the 32mm bore yields a higher 402N push force at 0.5 MPa. Note that a plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift. The fixed rubber bumper only softens the end of stroke and is not a locking mechanism. If adjustable cushioning is required for your application, look to the current MBLC line, as the MAL never offered this feature.
Upgrade checklist
- ✓ Order the MBL20X15UH (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 MBL20X15UH instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X15UH FAQ
Yes, the MAL20X15UH is discontinued. The exact drop-in replacement is the MBL20X15UH, offering identical bore, stroke, force, G1/8 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the 20mm bore provides 157N push and 132N pull force, 220N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
