This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X50CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X50CA 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-MAL40X50CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X50CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50CA
The AirTAC B01-MAL40X50CA is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL40X50CA, meaning it is mechanically identical to the standard model but grouped for specific customer builds. Delivering 628 N of push force at 0.5 MPa, it features a 40 mm bore, a 50 mm stroke, and a G1/4 port.
AirTAC replaced this legacy unit with the MBL40X50CA, a true drop-in replacement retaining the exact bore, stroke, output force, port size, and CA pivot mounting. The original MAL utilizes threaded front and back covers, whereas the upgraded MBL features a riveted rolling-packed body. Additionally, because this specific SKU lacks an -S magnet, it cannot accept a position sensor. If sensing is required on the new MBL, you must order the -S version and use the current CMSG, DMSG, or EMSG switch families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X50CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X50CA 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-MAL40X50CA Is Used
Injection Mold Ejection
Drives ejection pins on a 40-ton injection molding press, utilizing the 628 N push force at 0.5 MPa to break plastic parts free from the mold cavity.
Package Divert Arm
Actuates a pivoting diverter arm on a packaging conveyor, where the CA clevis mount accommodates the arcing motion of the sorting mechanism.
Pallet Stop Gate
Raises and lowers a physical stop gate at a palletizing station, relying on the 528 N pull force to retract the barrier clear of incoming loads.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50CA with B01-MBL40X50CA
To replace this discontinued cylinder, order the MBL40X50CA. Confirm your 40 mm bore, 50 mm stroke, PT thread, and CA pivot back cover (which swings on a pin to absorb arcing loads). If you need to step down in force, the 32 mm bore neighbor provides 402 N of push at 0.5 MPa; if you need more power, you would step out of the MAL/MBL mini range entirely to a larger profile cylinder. Note that the fixed rubber bumper on this MAL softens end-of-stroke impacts but is not an adjustable cushion—choose the current-line MBLC if you need adjustable air damping. Furthermore, a plain double-acting cylinder drifts when air is lost, so add an external rod lock if the load must be held safely during an outage.
Upgrade checklist
- ✓ Order the B01-MBL40X50CA (same bore/stroke/force)
- ✓ Same G1/4 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-MBL40X50CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50CA FAQ
Yes, the B01-MAL40X50CA (an application-dedicated variant of the base MAL40X50CA) is discontinued. The exact drop-in replacement is the MBL40X50CA, which offers the same 40 mm bore, 50 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and CA pivot mounting. The main difference is the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The full force figures are: 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If sensing is needed on the MBL replacement, order the -S option and use CMSG, DMSG, or EMSG switches.
