Bearing Edge Confusion?


Platinum Member
Can anyone explain the bearing edge lingo being used by Mapex for their new Panther snare lines? Some of the snare list bearing edges as "5:1, 9:2"--stuff like that. What does this mean? How does it translate to a degree-based edge?

I might be wrong but I think it refers to the angle of the bearing in ratio form, just like gradient markers for roads, so for example 9:2 might mean for the bearing every 9mm of in of thickness it has 2mm in height. It's basically a fancy way of expressing the angle of the bearing edge.

Does that man any sense?

I'm thinking it means the edge is 9mm wide for every 2mm of height. Are we saying the same thing.??

Yeah, instead of expressing the edge angle in degrees it's just in ratio form. A pain the ass if you ask me if you have any intention of comparing them to other manufacturers bearing edge angles.

Now, where did my graphics calculator go?
