This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X350SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X350SU 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).

The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X350SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 350mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X350SU, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL20X350SU is a discontinued compact double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the base MAL20X350SU, meaning it is mechanically identical to the standard model with a 20mm bore, 350mm stroke, and 157N push force at 0.5MPa. AirTAC replaced the legacy MAL line with the MBL series, making the MBL20X350SU your exact drop-in replacement. It delivers the same output force, G1/8 porting, and mounting interface.
This SKU features a built-in magnet (-S) for position sensing and a U flat-end back cover. Two engineering details define this cylinder: it relies on a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion, and its 8mm carbon-steel rod uses a 20um hard-chrome plating paired with a heterogeneous two-way grease-retaining seal. Because the original MAL uses threaded front and back covers while the newer MBL features a riveted rolling-packed body, upgrading is purely structural; the operational ratings remain unchanged.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X350SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The B01-MBL20X350SU 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.

Pushes a lightweight guide flap on a conveyor routing bare printed circuit boards, using the 350mm stroke to clear the production line during model changeovers.
Provides the 132N pull force at 0.5MPa to retract a small pick-head after seating delicate ribbon connectors into electronics housings.
Extends 350mm to fold the minor side flaps of small pharmaceutical cartons before they enter the case sealer, fitting easily into tight machine clearances.
To replace this discontinued cylinder, order the MBL20X350SU to match the 20mm bore, 350mm stroke, U flat-end back cover, and G1/8 port. Because this SKU includes the -S magnet, note that your older CS1-M or DS1-M switches will not fit the MBL; you must upgrade to the current CMSG, DMSG, or EMSG sensor family. The 350mm stroke on an 8mm rod means low side-load tolerance; use an external guide or pivot mount to prevent rod bending. If you need adjustable end-cushioning to soften impacts, step up to the MBLC20X350SU on the current line.
For sizing flexibility, you can step down to the smaller MAL16 bore (confirm from datasheet for exact force) if space is tight, or step up to the MAL25 bore (245N push at 0.5MPa) if your application requires more clamping power. Remember that a plain cylinder does not hold its load when air pressure drops; the bumper only softens the stroke end and is not a lock. Install an external rod lock or pilot-operated check valve if you need fail-safe position holding.
Upgrade checklist
Yes, the B01-MAL20X350SU is discontinued. The exact drop-in replacement is the MBL20X350SU, which matches the 20mm bore, 350mm stroke, U flat-end cover, and G1/8 port. The B01- prefix simply designated an application-specific build of the standard cylinder. The MBL upgrade uses a riveted body instead of threaded covers, but performance is identical.
At 0.5MPa it provides 157N push and 132N pull force; at 0.7MPa it provides 220N push, with a maximum theoretical force of 32kgf at 1.0MPa. Because this SKU has the -S magnet, it works with older CS1-M and DS1-M switches. When you switch to the MBL replacement, you must upgrade to CMSG, DMSG, or EMSG sensors.
