Ok... I'm kind of at a loss here. When I was looking at spindle design, and lead screw fixed end supports the thing seemed to be to get matched pairs of angular contact bearings that load up back to back or front to front when you clamp them together. Basically loads the bearing, end eliminates endplay until the bearings start to wear. In my ever expanding often misguided pursuit of knowledge I can't help but notice that there are nearly as many Double Row ACBs available as single row bearings. Are the double row just more surface area for greater load carrying capacity or are they preloaded in a "back to back" type internal configuration to eliminate endplay in place of two single row ACBs?
