This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X300SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X300SCA 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-MAL40X300SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X300SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SCA
The AirTAC B01-MAL40X300SCA 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 MAL40X300SCA, meaning it is mechanically identical to the standard catalog model. Delivering 628 N of push force at 0.5 MPa over a 300 mm stroke, it is replaced directly by the MBL40X300SCA. This drop-in successor matches the 40 mm bore, G1/4 port, M12x1.25 rod thread, and CA pivot mounting exactly.
The legacy MAL body uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. This specific SKU includes a magnet (-S) for position detection; the older MAL works with CS1-M / DS1-M switches, but the MBL replacement requires the current CMSG / DMSG / EMSG sensor family. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease around the hard-chrome plated carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X300SCA 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 | — |

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SCA Is Used
Pallet Divertor Arm
Uses the 628 N push force at 0.5 MPa to deflect heavy pallets on a packaging line, while the CA pivot absorbs the arcing motion of the 300 mm swing.
CNC Lathe Door Actuator
Extends 300 mm to open a machine tool safety enclosure, relying on the G1/4 port for rapid fill and the -S magnet to confirm door-closed position for interlocks.
Vertical Parts Elevator
Lifts a 300 mm stack of stamped metal brackets between conveyor tiers, requiring an external guide to protect the 16 mm rod from bending under the shifting load.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SCA with B01-MBL40X300SCA
To replace this discontinued cylinder, order the MBL40X300SCA. Confirm your 300 mm stroke, G1/4 port, PT thread form, and the CA pivot back cover, which swings on a pin to accommodate arcing loads. Because the -S magnet is present, plan to upgrade your sensors from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG switches. If your application requires adjustable air cushioning rather than a fixed rubber bumper, step up to the MBLC40X300SCA on the current line.
For sizing flexibility, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up is not available as 40 mm is the largest MAL mini round bore. At 300 mm of travel, the 16 mm rod has limited side-load tolerance; use an external guide or ensure the CA clevis pivots freely to prevent rod bending. A plain cylinder drifts when air is lost, so add an external rod lock if the load must be held.
Upgrade checklist
- ✓ Order the B01-MBL40X300SCA (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-MBL40X300SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SCA FAQ
Yes, the B01-MAL40X300SCA is discontinued. The exact drop-in replacement is the MBL40X300SCA, which matches the 40 mm bore, 300 mm stroke, G1/4 port, and CA pivot. The B01- prefix simply marks this as an application-dedicated variant of the base model. You must upgrade your position sensors, as the MAL -S magnet uses CS1-M / DS1-M switches while the MBL uses CMSG / DMSG / EMSG switches.
At 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a fixed rubber bumper, so if you need adjustable end-cushioning to absorb the kinetic energy of a heavy 300 mm stroke, you must use the MBLC variant on the current line.
