This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X175CALB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X175CALB 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 MAL20X175CALB
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X175CALB is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 175mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X175CALB, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X175CALB
The AirTAC MAL20X175CALB is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 175mm stroke. It delivers 157N of push force at 0.5MPa. The exact drop-in replacement is the MBL20X175CALB, which matches the bore, stroke, output force, G1/8 port, and LB foot mounting. The legacy MAL body uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU includes a CA pivot back cover and LB foot mounting, but lacks the -S magnet option, meaning it cannot accept a position sensor. Internally, the piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod is plated with 20um hard chrome to resist wear. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X175CALB 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 MBL20X175CALB 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 MAL20X175CALB Is Used
PCB Depaneling Router
Pushes a separator blade through 175mm of travel on an automated PCB depaneling machine, using the 157N push force at 0.5MPa to cleanly route rigid circuit boards.
Carton Flap Folder
Actuates a 175mm folding arm on a compact packaging line, relying on the LB foot bracket and CA pivot to swing small cardboard flaps into position for tape sealing.
IC Tube Transfer
Extends 175mm to push surface-mount component tubes into a testing rack, where the 8mm hard-chrome plated rod handles repetitive loading without scoring.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X175CALB with MBL20X175CALB
To replace the discontinued MAL20X175CALB, order the MBL20X175CALB. Verify your PT tapered port threads, the 175mm stroke, and the LB foot bracket combined with the CA pivot back cover. Because this 175mm stroke exceeds 300mm, the 8mm rod is vulnerable to bending under side loads—use the CA clevis to allow articulation or add an external guide rail to prevent rod damage. If you need to hold the load vertically upon air loss, add an external rod lock, as the bumper is not a locking device.
For sizing flexibility, stepping down to a 12mm bore is not an option in this series, but stepping up to the 25mm bore yields 245N of push force at 0.5MPa. If your application requires adjustable end-of-stroke cushioning rather than the standard fixed rubber bumper, specify the current-line MBLC20X175CALB instead of the standard MBL.
Upgrade checklist
- ✓ Order the MBL20X175CALB (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 MBL20X175CALB instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X175CALB FAQ
Yes, the MAL20X175CALB is discontinued. The exact drop-in replacement is the MBL20X175CALB, which matches the 20mm bore, 175mm stroke, G1/8 port, and LB/CA mounting. The MBL upgrades the body to a riveted rolling-packed design while retaining the same output force.
At 0.5MPa it pushes with 157N and pulls with 132N. At 0.7MPa the push force is 220N, and the maximum theoretical force is 32kgf at 1.0MPa. It cannot hold a load when air is lost; the fixed rubber bumper only softens the end of stroke and is not a lock.
