This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X300-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X300-U 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 MAL25X300-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X300-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-U
The AirTAC MAL25X300-U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Operating at 0.5 MPa, it generates 245 N of push force and 206 N of pull force over a 300 mm stroke. The exact drop-in replacement is the MBL25X300-U, which matches the original 25 mm bore, G1/8 port, and flat-end rear cover perfectly.
This legacy SKU features a U-type flat-end back cover for rigid, non-articulating mounting and lacks a built-in magnet, meaning it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for equally robust performance. Both designs rely on a fixed rubber bumper at the stroke ends rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X300-U 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 MBL25X300-U 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 MAL25X300-U Is Used
PCB router gate
Actuates a routing diverter on a printed circuit board assembly line, using the 245 N push force at 0.5 MPa to reliably shift lightweight aluminum pallets along a 300 mm path.
Pouch reject arm
Extends a paddle over 300 mm to knock defective sealed pouches off a packaging conveyor, relying on the compact 25 mm round body to fit between tight belt rollers.
Tray pusher
Transfers small component trays into a testing fixture, utilizing the rigid U-type flat-end back cover to maintain strict perpendicular alignment without pivot drift.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-U with MBL25X300-U
To replace the MAL25X300-U, order the MBL25X300-U. It is a true drop-in swap: confirm the 25 mm bore, 300 mm stroke, G1/8 port, and default PT tapered thread. Because this specific SKU has no -S magnet, it cannot support a position sensor. If you ever require end-of-stroke detection later, you must order an MBL25X25S variant and upgrade to the current CMSG or DMSG switch family, as the older CS1-M and DS1-M sensors are phased out.
When sizing, verify if 245 N push at 0.5 MPa is sufficient. Stepping down to a 20 mm bore drops the push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. Because this is a 300 mm stroke on a 10 mm rod, side-load tolerance is very low. You must use an external guide rail to prevent rod bending, as the fixed rubber bumper only softens end impacts and cannot hold the load if air pressure drops. For adjustable end-cushioning rather than a rubber bumper, look at the current MBLC line.
Upgrade checklist
- ✓ Order the MBL25X300-U (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 MBL25X300-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-U FAQ
Yes, the MAL25X300-U is discontinued. The exact drop-in replacement is the MBL25X300-U, offering the same 25 mm bore, 300 mm stroke, 245 N push force at 0.5 MPa, and G1/8 port. The main difference is the MBL uses a riveted rolling-packed body instead of the original threaded covers.
At 0.5 MPa, the push force is 245 N and pull is 206 N. At 0.7 MPa, push increases to 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M position sensors.
