About the AirTAC MSAL20
Discontinued: AirTAC has replaced the MSAL series with the MSBL series. Every MSAL code on this page is supplied as the current MSBL with the same code after the prefix, for example MSAL20X10CA ships as MSBL20X10CA. The specifications on this page are those of the MSBL you receive.
The AirTAC MSAL20 is a single-acting, spring-return aluminium-barrel mini cylinder (push type) with a 20 mm bore and an 8 mm piston rod. Compressed air extends the rod and a built-in spring retracts it when the air is released, so the rod rests retracted; only one port takes air. Catalog output with the spring force already deducted is 109.9 N push at 0.5 MPa and 172.7 N at 0.7 MPa. The spring stroke has no air behind it, so it must not carry a load.
All MSAL20 versions share 1/8" air ports, an M8×1.25 rod thread and rubber bumpers at both ends. The cylinder runs on filtered air between 0.2 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 50 to 800 mm/s. This page lists 56 stock order codes with strokes from 10 to 150 mm; the catalog maximum stroke is 150 mm.

AirTAC catalog values for the single-acting push type: air force on the full bore less the return-spring force. The spring stroke delivers no rated force.

Where the MSAL20 Is Used
Small pushers and stoppers
About 109.9 N at 0.5 MPa suits light pushers, stoppers, gates and ejectors.
Packaging and assembly
Compact strokes for feeders, diverters and assembly stations.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right MSAL20 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the back cover and mounting. The back cover sets how the rear of the cylinder is fixed or where its air enters (CA clevis-end cover, U flat-end cover). Mounting brackets on this page: LB foot bracket, SDB rear pivot bracket. A clevis-end cover with an SDB pivot bracket lets the cylinder swing; flat or round covers with an FA flange or LB foot hold it rigid.
Finally pick the version: S adds a magnet for position sensors.
AirTAC MSAL20 FAQ
Discontinued: AirTAC has replaced the MSAL series with the MSBL series. Every MSAL code on this page is supplied as the current MSBL with the same code after the prefix, for example MSAL20X10CA ships as MSBL20X10CA. The specifications on this page are those of the MSBL you receive.
Air extends the rod with about 109.9 N at 0.5 MPa (catalog value, spring force deducted); the internal spring retracts it when the port is vented. The force does not depend on the stroke code.
No. The return stroke is driven only by the internal spring, and AirTAC specifies that single-acting cylinders must not be loaded on it. Use a double-acting model if both directions must do work.
1/8" ports, PT thread as standard.
Back covers: CA clevis-end cover, U flat-end cover. Brackets: LB foot bracket, SDB rear pivot bracket. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.2 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single MSAL20. Orders are processed and handed to the carrier within 3-5 business days.
