When I worked on them, quite a few different bearing companies. A lot of them were Brenco, Timken, SKF and Hyatt, but FAG, Koyo and others were often seen as well.

The design of the bearings themselves are tapered rollers. Here's a cutaway:

They get packed with high pressure grease, one of the specifications is that the grease has to be certified to last 500,000 miles.

How many bearings per rail car?

I will say this, I bought some Timken wheel bearings for my Dodge A-100 (Front.11" drums) two months ago, and was Amazed that they were Made in USA ! They were fresh stock too. A Big thumbs up for Timken.

How many bearings per rail car?

Each axle has a bearing on each end, so one per wheel. Not all cars have four wheels, some depressed flats can have up to a dozen. And some articulated car sets have more than one car sharing a single truck of two axles..
