This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X250-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X250-S-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 MAL25X250-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X250-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-S-U
The AirTAC MAL25X250-S-U is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 250 mm stroke. It delivers 245 N push and 206 N pull at 0.5 MPa, utilizing a G1/8 port and a 10 mm carbon-steel rod with 20 um hard-chrome plating. The exact drop-in replacement is the MBL25X250-S-U, matching the bore, stroke, force, port, and U flat-end mounting. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This SKU includes the -S magnet for position sensing. On the MAL, this magnet pairs with older CS1-M or DS1-M reed switches, but upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and a heterogeneous two-way seal that retains grease. Because it lacks an adjustable cushion, buyers needing softer deceleration should specify the MBLC variant on the modern line.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X250-S-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 MBL25X250-S-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 MAL25X250-S-U Is Used
PCB Panel Reject Gate
Pushes a diverter gate on a SMT conveyor to route defective 250 mm wide PCB panels off the main belt using 245 N of push force at 0.5 MPa.
Carton Flap Tucker
Extends 250 mm to fold the minor side flaps of small corrugated shipping cartons prior to tape sealing, fitting within tight machine clearances.
Tooling Ejector Pin
Retracts a 10 mm ejector pin in a pneumatic press fixture, using the -S magnet and a CS1-M switch to verify the pin is clear before the cycle starts.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-S-U with MBL25X250-S-U
To replace the MAL25X250-S-U, order the MBL25X250-S-U. Confirm the 25 mm bore, 250 mm stroke, G1/8 port, and the default PT tapered thread. The U designation indicates a rigid flat-end back cover. Retain the -S magnet, but note the sensor family changes from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG switches. If 245 N push at 0.5 MPa is insufficient, step up to the 32 mm bore (402 N push); if you need less force, step down to the 20 mm bore (157 N push). For end-of-stroke damping, remember the MAL has a fixed rubber bumper, while the current MBLC offers an adjustable air cushion.
At 250 mm of travel, the 10 mm rod is susceptible to bending under lateral stress. Use an external guide rail to support the payload, as the fixed rubber bumper softens impact but does not lock the rod. A plain MAL or MBL cylinder will drift if air pressure is lost, so add an external rod lock or pilot-operated check valve if the load must be held vertically.
Upgrade checklist
- ✓ Order the MBL25X250-S-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 MBL25X250-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-S-U FAQ
Yes, the MAL25X250-S-U is discontinued. The exact drop-in replacement is the MBL25X250-S-U, offering the same 25 mm bore, 250 mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted body instead of threaded covers, and the -S magnet now requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The cylinder operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
