This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X50-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X50-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 MAL25X50-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-CM is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X50-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-CM
The AirTAC MAL25X50-CM is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 50 mm stroke. It delivers 245 N push and 206 N pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X50-CM, which matches the bore, stroke, output force, G1/8 port, and CM round-end mounting exactly. You can install the MBL without modifying your existing fixture.
This legacy MAL cylinder features a threaded front and back cover design, whereas the modern MBL replacement utilizes a riveted rolling-packed body for structural rigidity. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. Internally, the piston relies on a heterogeneous two-way seal that retains grease, running alongside a self-lubricating front-cover bearing guide.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-CM Technical Specifications

| Stroke | 50 mm |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X50-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 MBL25X50-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 MAL25X50-CM Is Used
Pouch Sealing Jaw Pivot
Uses the 245 N push at 0.5 MPa to close sealing jaws on a vertical form-fill-seal machine, with the CM round-end accommodating the slight arc of the linkage.
PCB Test Socket Actuation
Drives a 50 mm stroke to lower an electrical test probe onto printed circuit boards, relying on the compact 25 mm aluminum body to fit dense testing arrays.
Carton Flap Folder
Pushes minor flaps inward on a packaging line, where the 206 N pull force safely retracts the rod despite minor mechanical friction from the cardboard.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-CM with MBL25X50-CM
To replace the MAL25X50-CM, order the MBL25X50-CM. Confirm your 50 mm stroke, G1/8 port, and PT thread form. The CM round-end back cover provides a pivot point for slight arcing loads, differing from a rigid flat-end U cover. If your application requires an adjustable air cushion instead of the standard fixed rubber bumper, step up to the current MBLC series. If you ever need position sensing, note this SKU has no magnet; you would need an MBL25X50S-CM which uses the modern CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M.
For sizing flexibility, stepping down to a 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. Remember that a plain cylinder does not hold a load when air pressure is lost; the bumper only softens end-of-stroke impact. For secure positioning, add an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL25X50-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 MBL25X50-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-CM FAQ
Yes, the MAL25X50-CM is discontinued. The exact drop-in replacement is the MBL25X50-CM. It shares the exact same 25 mm bore, 50 mm stroke, G1/8 port, and CM round-end mounting. The main physical change is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. This specific CM configuration operates at speeds of 30-800 mm/s.
