This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X50SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X50SCA 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 B01-MAL Special Purpose Cylinder B01-MAL25X50SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X50SCA 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 B01-MBL25X50SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X50SCA
The AirTAC B01-MAL25X50SCA is a discontinued, double-acting aluminum mini round cylinder. The "B01-" prefix designates this as an application-dedicated (customer-specified) variant of the base MAL25X50SCA, meaning it shares the exact same 25mm bore, 50mm stroke, and mechanical specs. This cylinder delivers 245N of push force at 0.5 MPa. AirTAC replaced the MAL line with the MBL series, making the MBL25X50SCA your exact drop-in replacement, matching the bore, stroke, output force, G1/8 port, and CA pivot mounting.
Mechanically, the legacy MAL features threaded front and back covers, whereas the current MBL body utilizes a riveted rolling-packed construction. This SKU includes the -S magnet for position sensing; note that the MAL uses older CS1-M or DS1-M switches, while the replacement MBL requires the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 um hard-chrome plating. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X50SCA 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 B01-MBL25X50SCA 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 B01-MAL Special Purpose Cylinder B01-MAL25X50SCA Is Used
PCB Depaneling Router
Pushes a 25mm stroke pin to clamp circuit boards during routing, using the 245N force at 0.5 MPa to prevent substrate vibration.
Carton Flap Folder
Deploys the 50mm stroke at high speed to fold small corrugated box flaps, relying on the CA pivot to self-align during the arc motion.
Connector Insertion Press
Drives a 10mm rod with 343N at 0.7 MPa to seat pin headers into plastic housings without damaging the delicate components.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X50SCA with B01-MBL25X50SCA
To replace the B01-MAL25X50SCA, order the MBL25X50SCA. It drops directly into your existing setup with the same 25mm bore, 50mm stroke, PT thread form, G1/8 port, and CA pivot back cover. Because your SKU has the -S magnet, you must update your sensors: the MBL will not accept the older CS1-M/DS1-M switches and requires CMSG, DMSG, or EMSG models. If you need to adjust the bore size, stepping down to the 20mm bore yields 157N of push force at 0.5 MPa, while stepping up to the 32mm bore provides 402N.
The CA back cover acts as a pivot clevis, allowing the cylinder to swing on a pin to absorb arcing loads. Keep in mind the fixed rubber bumper softens end-of-stroke impacts but is not an adjustable air cushion; if your application requires precise end-of-stroke deceleration, look at the current MBLC line. Additionally, a plain cylinder does not hold its position if air pressure drops—the rod will drift. For vertical loads, install an external rod lock or pilot-operated check valve.
Upgrade checklist
- ✓ Order the B01-MBL25X50SCA (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 B01-MBL25X50SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X50SCA FAQ
Yes, the B01-MAL25X50SCA is discontinued. The exact drop-in replacement is the MBL25X50SCA, which matches the 25mm bore, 50mm stroke, CA pivot, and G1/8 port. The B01- prefix simply marks it as an application-dedicated variant, so the MBL replacement functions identically.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it supports position sensing; the MAL uses CS1-M or DS1-M switches, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
