This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X150-S-CM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL20X150-S-CM
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X150-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CM
The AirTAC MAL20X150-S-CM is a discontinued compact double-acting aluminum mini round cylinder engineered for tight spaces. Delivering 157 N of push force and 132 N of pull force at 0.5 MPa, it features a 20 mm bore, a 150 mm stroke, and a G1/8 port. Because this legacy series has reached end-of-life, the direct replacement is the MBL20X150-S-CM, which matches the exact bore, stroke, output force, port size, and mounting interface.
This specific SKU includes a built-in magnet (-S) for position sensing and a CM round-end back cover. The original MAL body utilized threaded front and back covers, whereas the modern MBL upgrade features a riveted rolling-packed body for enhanced structural integrity. Furthermore, while the MAL magnet interfaces with legacy CS1-M or DS1-M reed switches, the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way grease-retaining seal alongside a self-lubricating front-cover bearing guide.

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CM Is Used
PCB Depaneling Router
Provides 157 N of push force at 0.5 MPa to actuate the cutting blade assembly in compact desktop PCB routing machines.
Chip Tray Ejector
Uses the 150 mm stroke to push populated integrated circuit trays out of a testing oven, relying on the -S magnet for precise timing.
Small Bag Diverter
Employs the CM round-end cover to pivot smoothly and deflect lightweight pouches on a packaging conveyor belt.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CM with MBL20X150-S-CM
To replace the MAL20X150-S-CM, order the MBL20X150-S-CM, ensuring you keep the CM round-end back cover and the -S magnet option. Be aware that upgrading means switching your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG families. The 150 mm stroke on an 8 mm rod necessitates an external guide or pivot mount to prevent rod bending under side loads. If you need to step down, the smallest available bore is this 20 mm (157 N push at 0.5 MPa); if you need more force, step up to the 25 mm bore (245 N push at 0.5 MPa). Note that the fixed rubber bumper is not an adjustable cushion; for cushioning control, specify an MBLC on the current line. A plain MAL or MBL will not hold a load if air pressure drops, so add an external rod lock for vertical applications.
Upgrade checklist
- ✓ Order the MBL20X150-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 MBL20X150-S-CM instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CM FAQ
Yes, the MAL20X150-S-CM is discontinued. The direct replacement is the MBL20X150-S-CM, offering the same 20 mm bore, 150 mm stroke, 32 kgf max force, G1/8 port, and CM round-end mounting. You must update your sensors from the older CS1-M/DS1-M to the current CMSG/DMSG/EMSG family.
This 20 mm bore cylinder has a G1/8 port and an 8 mm rod. The output force is 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa.
