I was going through the datasheet of a 17 CFM 230v fan...It was mentioned that there are two types of ball bearings i.e. terminal ball bearing and wire lead ball bearing...Is there any difference between them??
Just electrical connection physical details, if they're not
otherwise differentiated. One will have mini spade lugs,
the other a wire pigtail from the look of it.
It's not about the bearings, fan descriptions just concatenate
whatever details they think matter. Both are ball bearing
and balls is balls more or less.
