This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X210SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X210SCM 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-MAL20X210SCM
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X210SCM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 210mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X210SCM, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X210SCM
The AirTAC B01-MAL20X210SCM 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 MAL20X210SCM, meaning it is mechanically identical to the standard catalog model. Delivering 157 N of push force at 0.5 MPa, it features a 20 mm bore, a 210 mm stroke, and a built-in magnet. AirTAC replaced the entire MAL line with the MBL series, making the MBL20X210SCM your exact drop-in replacement.
This legacy unit has threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body. The CM round-end back cover on this SKU is designed for clevis mounting to accommodate slight arcing motions. Because it carries the -S magnet option, it originally paired with CS1-M or DS1-M reed switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X210SCM 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-MAL20X210SCM Is Used
PCB Conveyor Diverter
Pushes lightweight circuit boards laterally across a tight electronics assembly conveyor using 157 N of force at 0.5 MPa.
Connector Insertion Press
Provides a precise 210 mm extension to seat ribbon cable connectors into chassis motherboards within cramped enclosures.
Parts Ejection Gate
Actuates a small pivot gate using the CM round-end cover to release plastic injection-molded components from a sorting bin.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X210SCM with B01-MBL20X210SCM
To replace the B01-MAL20X210SCM, order the MBL20X210SCM. This drop-in upgrade matches the 20 mm bore, 210 mm stroke, G1/8 port, PT thread, and CM round-end back cover exactly. If you need to adjust the force, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa. Since the 210 mm stroke exceeds 300 mm, the 8 mm piston rod has a low tolerance for side loads; use an external guide rail or a pivot clevis to prevent rod bending. If your application requires adjustable cushioning instead of the standard fixed rubber bumper, look to the MBLC variant on the current line. Note that a plain cylinder does not hold position when air is lost, so add an external rod lock for vertical loads.
Upgrade checklist
- ✓ Order the B01-MBL20X210SCM (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-MBL20X210SCM instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X210SCM FAQ
Yes, the B01-MAL20X210SCM is discontinued. The exact drop-in replacement is the MBL20X210SCM, which matches the 20 mm bore, 210 mm stroke, G1/8 port, and CM mounting. The B01- prefix simply designated an application-specific build of the standard MAL cylinder. When upgrading, your -S magnet sensors must change from the older CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG families.
At 0.5 MPa, the 20 mm bore provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
