This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X450-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X450-CM 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 MAL25X450-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-CM is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X450-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-CM
The AirTAC MAL25X450-CM is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 450 mm stroke, delivering 245 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL25X450-CM, which matches the bore, stroke, output force, G1/8 port, and CM round-end mounting. The legacy MAL features threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for equally robust performance.
This specific SKU lacks a built-in magnet, meaning it cannot support a position sensor. The Ø10 mm carbon-steel rod features 20 um hard-chrome plating and rides on a self-lubricating front-cover bearing guide. A heterogeneous two-way seal retains grease for consistent friction, while end-of-travel impacts are absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X450-CM 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 MBL25X450-CM 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 MAL25X450-CM Is Used
PCB Conveyor Diversion
Actuates a routing gate on a printed circuit board conveyor, using the 450 mm stroke to shift panels between parallel processing lanes with 245 N of push force.
Carton Flap Folding
Extends to fold secondary corrugated carton flaps prior to tape sealing, relying on the CM round-end back cover to accommodate slight angular misalignment during the 450 mm travel.
Textile Yarn Guide
Traverses a yarn guide carriage across a weaving loom beam, where the lightweight aluminum body and 343 N force at 0.7 MPa provide reliable lateral positioning.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-CM with MBL25X450-CM
To replace the MAL25X450-CM, order the MBL25X450-CM. Confirm the 25 mm bore, 450 mm stroke, PT tapered port thread, and CM round-end back cover are correct for your assembly. Because this unit has no -S magnet, it cannot accept CS1-M or DS1-M sensors; if position detection is required, switch to an MBL25X450S-CM and use the current CMSG, DMSG, or EMSG switch family.
For sizing flexibility, stepping down to a 20 mm bore yields 157 N of push at 0.5 MPa, while stepping up to a 32 mm bore provides 402 N. At 450 mm, the stroke is highly susceptible to side-loading and rod bending on the 10 mm rod; use external guide rails or ensure the CM round-end pivots freely to prevent premature seal wear. The fixed rubber bumper softens end stops, but if your load requires adjustable deceleration, specify the current-line MBLC variant. A plain cylinder does not hold position upon air loss, so add an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL25X450-CM (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 MBL25X450-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-CM FAQ
Yes, the MAL25X450-CM is discontinued. The exact drop-in replacement is the MBL25X450-CM. It offers the same 25 mm bore, 450 mm stroke, G1/8 port, CM round-end cover, and 245 N push force at 0.5 MPa. The primary upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 25 mm bore generates 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific MAL25X450-CM SKU lacks an -S magnet, it cannot accept position sensors like the CS1-M or DS1-M; you must order a magneted version for detection.
