This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X300SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X300SCA 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-MAL20X300SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X300SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCA
The AirTAC B01-MAL20X300SCA is a discontinued double-acting aluminum mini round cylinder. The B01- prefix designates an application-dedicated, customer-specified variant that is mechanically identical to the base MAL20X300SCA, delivering 157 N of push force at 0.5 MPa. AirTAC replaced this legacy series with the MBL20X300SCA, a true drop-in upgrade retaining the exact 20 mm bore, 300 mm stroke, G1/8 port, and CA pivot mounting.
This cylinder features a fixed rubber bumper and a heterogeneous two-way grease-retaining seal. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it was designed for the older 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-MBL20X300SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCA Is Used
PCB Depaneling Router
Pushes a linear cutting tool carriage across 300 mm to singulate printed circuit boards, relying on the 157 N push force and CA pivot to absorb slight carriage misalignments.
Small Part Sorting Diverter
Extends a flap over 300 mm to route small plastic injection-molded components on a conveyor belt, using the compact 20 mm bore to fit within tight machine guarding.
Test Handler Escapement
Actuates a 300 mm sliding gate to release semiconductor packages into test trays, requiring the -S magnet and CS1-M sensor to confirm gate open/close positions.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCA with B01-MBL20X300SCA
To replace this discontinued cylinder, order the MBL20X300SCA. Verify your 300 mm stroke, G1/8 port, PT thread, and CA pivot back cover. The CA clevis allows the body to swing on a pin, which is critical for absorbing arcing rod movements over this long 300 mm travel. If your application requires adjustable end-cushioning instead of the standard fixed rubber bumper, step up to the MBLC20X300SCA on the current line. Note that a plain cylinder does not hold position if air pressure drops; add an external rod lock for vertical loads.
When sizing, consider stepping down to the 12 mm bore class for lighter duty, or stepping up to the 25 mm bore (245 N push at 0.5 MPa) if you need more force. With an 8 mm rod extending 300 mm, side-load tolerance is minimal; you must use an external guide rail or rely on the CA pivot to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBL20X300SCA (same bore/stroke/force)
- ✓ Same G1/8 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-MBL20X300SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCA FAQ
Yes, the B01-MAL20X300SCA is discontinued. The exact drop-in replacement is the MBL20X300SCA, offering the same 20 mm bore, 300 mm stroke, G1/8 port, and CA pivot. The B01- prefix simply marks it as an application-dedicated variant of the base MAL model. You must upgrade your -S magnet sensors from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches.
The bore is 20 mm with a G1/8 port. At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It uses an 8 mm rod with an M8x1.25 rod-end thread.
