This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X420SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X420SCA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 420mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X420SCA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA
The AirTAC MAL25X420SCA is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 420mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. Because this legacy series has reached end-of-life, the exact drop-in replacement is the MBL25X420SCA, which matches the bore, stroke, force, port size, and CA pivot mounting perfectly.
This SKU includes a built-in magnet (-S) for position sensing; however, the older CS1-M and DS1-M switches used on the MAL are superseded by the current CMSG, DMSG, and EMSG sensor family on the MBL replacement. Structurally, the MAL relies on threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for enhanced integrity. Both generations use 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 MBL25X420SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X420SCA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA Is Used
Pallet Diverters
Steers small pallets along curved conveyor sections using the CA pivot bracket to accommodate the arcing motion over the 420mm extension.
PCB Shuttle Ejection
Pushes populated circuit board shuttles out of a test fixture, relying on the 245N force at 0.5MPa and the -S magnet to confirm ejection.
Carton Flap Folding
Folds corrugated carton flaps in tight packaging lanes where the compact 25mm aluminum body fits between adjacent guide rails.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA with MBL25X420SCA
To replace your MAL25X420SCA, order the MBL25X420SCA and confirm the PT thread form, CA pivot back cover, and magnet option are retained. If your application requires position holding, note that neither the MAL nor the MBL locks the rod when air pressure is lost—you will need an external rod lock or pilot-operated check valve. If a cushion is needed to absorb kinetic energy at the end of this 420mm stroke, the fixed rubber bumper cannot be adjusted; instead, look at the current-line MBLC variant which offers adjustable air cushioning.
For sizing flexibility, stepping down to the 20mm bore yields 157N of push force at 0.5MPa, while stepping up to the 32mm bore provides 402N. Because the 420mm stroke is substantial for a 10mm rod, side-load tolerance is low; the CA pivot back cover on this unit is essential for arcing loads, but you should still use an external guide rail to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X420SCA (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 MBL25X420SCA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420SCA FAQ
Yes, the MAL25X420SCA is discontinued. The exact drop-in replacement is the MBL25X420SCA, offering the same 25mm bore, 420mm stroke, CA pivot mounting, and G1/8 port. The MBL body uses a riveted rolling-packed design instead of threaded covers, and its -S magnet requires CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
At 0.5MPa, the push force is 245N and the pull force is 206N. At 0.7MPa, the push force is 343N. The maximum theoretical force is 50kgf at 1.0MPa. The cylinder operates at speeds of 30-800mm/s and uses a fixed rubber bumper for end-of-stroke damping.
