This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X155SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X155SCM 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 MAL20X155SCM
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155SCM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 155mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X155SCM, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155SCM
The AirTAC MAL20X155SCM is a discontinued double-acting aluminum mini round cylinder featuring a 20mm bore, 155mm stroke, and a built-in magnet. It delivers 157N of push force and 132N of pull force at 0.5MPa. The exact drop-in replacement is the MBL20X155SCM, which matches the bore, stroke, output force, G1/8 port, and CM round-end mounting. This legacy cylinder uses a fixed rubber bumper for end-of-stroke damping and a heterogeneous two-way seal that retains grease for long-term lubrication.
This specific SKU includes a CM round-end back cover, ideal for accommodating slight rotational misalignment in pivot-mount assemblies. The 8mm carbon-steel rod features 20um hard-chrome plating to resist wear. If you relied on the -S magnet for position sensing, note that the MAL used older CS1-M or DS1-M switches, whereas the modern MBL replacement requires CMSG, DMSG, or EMSG sensors. The legacy MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body for enhanced structural integrity.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X155SCM 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 MBL20X155SCM 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 MAL20X155SCM Is Used
Textile Loom Guide
Actuates a 155mm yarn guide arm in a textile loom, utilizing the 157N push force at 0.5MPa to shift the threading mechanism smoothly between tension gates.
PCB Edge Conveyor
Extends 155mm to push populated PCB panels out of an inspection station, with the CM round-end absorbing slight angular misalignment on the ejection arm.
Carton Flap Folder
Drives a compact folding blade inside a tight packaging machine cavity, retracting 132N at 0.5MPa to pull the cardboard flap squarely against the sealing rollers.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155SCM with MBL20X155SCM
To replace the MAL20X155SCM, order the MBL20X155SCM. Confirm your 155mm stroke requirement, the G1/8 port size, and the default PT tapered thread form. The CM round-end back cover must be retained to maintain your existing pivot joint mechanics. Because this SKU includes the -S magnet, you must update your position sensors from the legacy CS1-M/DS1-M family to the current CMSG/DMSG/EMSG switches used on the MBL.
With a 155mm stroke, the 8mm rod is susceptible to bending under offset loads; use an external guide rail or a pivot joint to manage side-load forces. If you need to step down to the smallest available bore, the neighbouring 20mm bore is the minimum size. If your application requires more force, step up to the 25mm bore, which provides 245N of push force at 0.5MPa. Remember that the fixed rubber bumper is not a lock; the rod will drift if air pressure is lost, so add an external rod lock for position holding. If end-of-stroke impact is too harsh, the current-line MBLC offers an adjustable air cushion the MAL never had.
Upgrade checklist
- ✓ Order the MBL20X155SCM (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 MBL20X155SCM instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155SCM FAQ
Yes, the MAL20X155SCM is discontinued. The exact drop-in replacement is the MBL20X155SCM, which offers the same 20mm bore, 155mm stroke, 157N push force at 0.5MPa, G1/8 port, and CM round-end mounting.
At 0.5MPa it provides 157N push and 132N pull force, 220N push at 0.7MPa, and a maximum theoretical force of 32kgf at 1.0MPa. The -S magnet works with legacy CS1-M/DS1-M switches, but the MBL replacement requires CMSG/DMSG/EMSG sensors.
