In response to a previous posting, on the UP 9000 series 4-12-2 steamers, Practical Pig asks:

“How much better would they run with roller bearings all around?  I wonder how expensive these were compared to the normal floating bushings on crankpins?  How much were those?  They were just some kind of soft babbitt metal, I think.  Were roller bearings as much as ten times more expensive at the start of it all?”

Timken Roller Bearing Assembly -- 100209

This image from Wikipedia is of an early Timken roller bearing — note the use of grooved rollers.  Obviously, this isn’t very exciting to look at…or is it?  This tapered bearing race on rollers alone made the mechanical late-modern completely possible, and it is difficult if not impossible to imagine how so many of the gizmoes we take for granted could even have existed without it.  It reduced the inertial resistance of huge static weights and masses to a fraction and made the more efficient transmission of power in vehicles, most of all, economically possible.  Indeed, I would go further and say that only with antigravity (or at least magnetic levitation!) may we even speak of any sort of historical movement era beyond roller bearings. 

Now here is a postmodern descendent from (more…)
