This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X700-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X700-S-CM 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 700mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X700-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM
The AirTAC MAL20X700-S-CM is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and a 700mm non-standard made-to-order stroke. It delivers 157N of push force at 0.5MPa and uses a G1/8 port with an 8mm hard-chrome plated carbon-steel rod. The exact drop-in replacement is the MBL20X700-S-CM, which matches the bore, stroke, output force, port, and CM round-end mounting.
This legacy unit features a built-in magnet (-S) for position detection and a CM round-end back cover. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Additionally, the MAL -S magnet interfaces with older CS1-M or DS1-M reed switches, while the MBL upgrade requires the current CMSG, DMSG, or EMSG sensor families. The MAL relies on a fixed rubber bumper, so if adjustable end-cushioning is needed for this long stroke, the MBLC variant on the current line should be specified instead.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X700-S-CM 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 MBL20X700-S-CM 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM Is Used
PCB Conveyor Diversion
Pushes lightweight PCB trays across a 700mm conveyor belt using 157N of force, with the -S magnet confirming full extension via a CS1-M sensor.
Carton Flap Folding
Extends 700mm to fold long cardboard flaps on a packaging line, relying on the CM round-end cover to absorb minor trajectory misalignments.
Textile Yarn Guiding
Cycles continuously to shift a yarn carrier across a wide weaving loom, benefiting from the self-lubricating front-cover bearing guide.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM with MBL20X700-S-CM
To replace the MAL20X700-S-CM, order the MBL20X700-S-CM. Confirm the 20mm bore, 700mm stroke, PT thread, G1/8 port, and CM round-end back cover. Because this SKU includes the -S magnet, you must update your sensing electronics: the older CS1-M and DS1-M switches will not fit the MBL, so select a CMSG, DMSG, or EMSG sensor. The 700mm stroke is non-standard and exceeds the 500mm maximum standard stroke, making it a special-order item.
When sizing, verify if the 157N push force at 0.5MPa is sufficient. Stepping up to the 25mm bore neighbor yields 245N, while stepping down to the smallest 20mm class leaves no smaller mini round option in this family. A 700mm stroke on an 8mm rod creates a severe bending risk; the compact rod has low side-load tolerance. You must use an external guide rail or a pivot mount to prevent rod damage. Furthermore, a plain MAL or MBL cylinder does not hold its load when air pressure drops—the rod drifts. Use an external rod lock or pilot-operated check valve for vertical loads. If end-of-stroke impact is an issue, upgrade to the MBLC for adjustable air cushions instead of the fixed rubber bumper.
Upgrade checklist
- ✓ Order the MBL20X700-S-CM (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 MBL20X700-S-CM instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X700-S-CM FAQ
Yes, the MAL20X700-S-CM is discontinued. The exact drop-in replacement is the MBL20X700-S-CM, offering identical bore, stroke, force, G1/8 port, and mounting. You must swap your CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches on the new MBL.
At 0.5MPa, the 20mm bore provides 157N of push force and 132N of pull force. At 0.7MPa, push increases to 220N. The theoretical maximum force is 32kgf at 1.0MPa.
