Continuous use of a manual slack adjuster?

[Frank S]

Anyone on here ever use a manual slack adjuster for continuous operation as a speed reducer?
Just wondering how one would stand up.
Also I would like to know what the ratio is.

They are not exactly made to be used as a speed reducer there are no bearings inside of them just bushings
If you wanted to use one as reduction gear for something like a weld positioner they work great and last quite a long time if you keep the worm and gear well greased. You can turn them with a drill motor at low RPM intermittently.
I wouldn't want to use on as a speed reducer without remanufacturing it with bearings and a proper housing.
I turned 1 into a torque multiplier once, before I bought a real one But I don't remember the ratio though
