This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X350SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X350SCA 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-MAL40X350SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 350mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X350SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350SCA
The AirTAC B01-MAL40X350SCA is a discontinued double-acting aluminum mini round cylinder built for a 350 mm stroke. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base MAL40X350SCA, meaning it is mechanically identical to the standard catalog model. Delivering 628 N of push force at 0.5 MPa, it features a G1/4 port, a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating, and a CA pivot back cover. AirTAC replaced this legacy series with the MBL40X350SCA, a drop-in upgrade retaining the exact same bore, stroke, output force, port size, and mounting interface.
The original MAL body used threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for equally robust performance. Because this SKU includes the -S magnet, it was designed to work with the older CS1-M and DS1-M reed switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke deceleration and uses a heterogeneous two-way seal that retains grease for long service life.

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-MBL40X350SCA 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-MAL40X350SCA Is Used
Pallet Divertor Arm
Uses the 628 N push force at 0.5 MPa to deflect heavy cardboard pallets on a packaging line, relying on the CA pivot to accommodate the arc of the swing mechanism.
CNC Lathe Door Operator
Cycles a sliding machine tool door over the 350 mm stroke, where the self-lubricating front-cover bearing guide ensures smooth operation without external grease maintenance.
Warehouse Lift Gate
Raises a lightweight loading ramp in a logistics sorter, benefiting from the two-way grease-retaining seal that prevents dry running in high-frequency duty cycles.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350SCA with B01-MBL40X350SCA
To replace the discontinued B01-MAL40X350SCA, order the MBL40X350SCA. This drop-in solution matches the 40 mm bore, 350 mm stroke, G1/4 port, PT thread form, CA pivot back cover, and built-in magnet. If you need to adjust the bore size, stepping down to the 32 mm neighbor yields 402 N of push force at 0.5 MPa, while stepping up is not an option as 40 mm is the largest available MAL/MBL mini round bore. Because the -S magnet is present, remember that your existing CS1-M or DS1-M switches will not fit the MBL body; you must migrate to CMSG, DMSG, or EMSG sensors.
With a 350 mm stroke, the Ø16 mm rod is susceptible to bending under lateral stress. The CA clevis back cover is specifically designed to accommodate this by pivoting on a pin to absorb arcing loads, but you should still verify external guide rails are used for heavy loads. The fixed rubber bumper softens impact but does not lock the rod; if position holding is required when air pressure drops, install an external rod lock or pilot-operated check valve. If your application requires adjustable end-cushioning to handle the kinetic energy of this long stroke, look at the MBLC40X350SCA variant on the current line instead of the standard MBL.
Upgrade checklist
- ✓ Order the B01-MBL40X350SCA (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-MBL40X350SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350SCA FAQ
Yes, the B01-MAL40X350SCA is discontinued. The exact drop-in replacement is the MBL40X350SCA, which shares the same 40 mm bore, 350 mm stroke, G1/4 port, and CA pivot mounting. The B01- prefix simply designated an application-specific build of the standard MAL cylinder, so the MBL matches it mechanically. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade your CS1-M/DS1-M sensors to the CMSG/DMSG/EMSG family.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. The cylinder operates at 30-800 mm/s and uses a fixed rubber bumper, not an adjustable air cushion.
