This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X125SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X125SCA 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-MAL20X125SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X125SCA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X125SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X125SCA
The AirTAC B01-MAL20X125SCA 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 MAL20X125SCA, meaning it is mechanically identical to the standard model. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC replaced the entire MAL family with the MBL line, making MBL20X125SCA the exact drop-in replacement. It shares the same 20 mm bore, 125 mm stroke, G1/8 port, and CA pivot mounting.
This legacy unit features a threaded front and back cover assembly, whereas the modern MBL utilizes a riveted rolling-packed body. The -S magnet on this SKU was designed for older CS1-M or DS1-M reed switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor families. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear. End-of-stroke deceleration relies on a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure drops.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X125SCA 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 | — |
| Max (@1.0 MPa) | 32 kgf | |
The B01-MBL20X125SCA 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-MAL20X125SCA Is Used
PCB Routing Gate
Actuates a lightweight diverter gate on a printed circuit board conveyor, using the 125 mm stroke to route panels into testing stations with 157 N of push force.
Carton Flap Folder
Extends 125 mm to fold minor flaps on small packaging cartons, where the CA pivot bracket absorbs slight misalignment during the folding arc.
Lab Tube Ejector
Pushes sample racks out of a centrifuge carousel, relying on the compact 20 mm body to fit within tight laboratory automation spaces.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X125SCA with B01-MBL20X125SCA
To replace the B01-MAL20X125SCA, order the MBL20X125SCA. Confirm your PT thread form, the G1/8 port, and the CA clevis back cover, which allows the cylinder body to swing on a pin to accommodate arcing loads. Because this is a 125 mm stroke on an 8 mm rod, side-load tolerance is low; ensure your CA pivot or an external guide absorbs any radial stress. If your application requires adjustable air cushioning instead of the fixed rubber bumper, step up to the MBLC equivalent. Note that a plain cylinder drifts when air is lost, so add an external rod lock for vertical or gravity-loaded applications.
When sizing, verify if the 20 mm bore fits your requirements. Stepping down is not an option as this is the smallest available size. If you need more force, the next size up is the 32 mm bore, which provides 402 N of push force at 0.5 MPa. If you need to detect piston position, remember the MBL replacement mandates a sensor upgrade from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG switches.
Upgrade checklist
- ✓ Order the B01-MBL20X125SCA (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-MBL20X125SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X125SCA FAQ
Yes, the B01-MAL20X125SCA is discontinued. The exact drop-in replacement is the MBL20X125SCA, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and CA mounting. The B01- prefix simply denotes an application-dedicated variant of the base cylinder, so the MBL functions identically. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG if you use the magnet.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. The cylinder operates at 30-800 mm/s and uses a fixed rubber bumper for end-of-stroke cushioning.
