This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X50SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X50SCA 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-MAL40X50SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50SCA 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-MBL40X50SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50SCA
The AirTAC B01-MAL40X50SCA is a discontinued, double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant, mechanically identical to the standard MAL40X50SCA. It delivers 628 N of push force at 0.5 MPa and features a 16 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced the MAL series with the MBL line, making the MBL40X50SCA your exact drop-in replacement.
This 40 mm bore unit uses a G1/4 port and a CA pivot back cover designed to swing on a pin for arcing loads. The legacy MAL body relies on threaded front and back covers, whereas the current MBL utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it originally paired with CS1-M / DS1-M switches; upgrading to the MBL requires switching to the current CMSG / DMSG / EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X50SCA 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-MBL40X50SCA 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-MAL40X50SCA Is Used
Pneumatic Stamping Press
Drives a short 50 mm stroke stamping die with 628 N of push force at 0.5 MPa to crimp small sheet metal enclosures.
Package Divert Arm
Uses the CA pivot back cover to swing a sorting arm smoothly through an arc, routing medium-weight cartons on a distribution line.
Pallet Lift Gate
Actuates a 50 mm lifting gate to lower heavy product trays, relying on the 16 mm hard-chrome plated rod to resist deflection.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50SCA with B01-MBL40X50SCA
To replace this cylinder, order the MBL40X50SCA. It matches the 40 mm bore, 50 mm stroke, G1/4 port, PT thread, and CA pivot back cover exactly. If you need to adjust the force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, while no larger mini round bore exists in this family. The -S magnet on your current unit means you must migrate from the older CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG switches on the MBL. The fixed rubber bumper softens end-of-stroke impact, but if your application requires adjustable cushioning, look at the MBLC variant on the current line. A plain bumper does not hold position; install an external rod lock if the load must be prevented from drifting upon air loss.
Upgrade checklist
- ✓ Order the B01-MBL40X50SCA (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-MBL40X50SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X50SCA FAQ
Yes, the B01-MAL40X50SCA is discontinued. The exact drop-in replacement is the MBL40X50SCA, which shares the same 40 mm bore, 50 mm stroke, CA pivot back cover, and G1/4 port. The B01- prefix simply denotes an application-dedicated variant of the base model, so the MBL replacement functions identically.
At 0.5 MPa it provides 628 N push and 528 N pull force, increasing to 880 N push at 0.7 MPa, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it uses the older CS1-M / DS1-M switches; if you upgrade to the MBL replacement, you must switch to the current CMSG / DMSG / EMSG sensor family.
