Re: [atlas_craftsman] Re: headstock bearing replacement
- For the most part bearing pricing is a function of volume and
competition....unique items available from a single source tend to be at the high end of
range while garden variety available from several sources tend to be modestly
priced. Bearing supplier makes more
profit selling a quantity of modestly priced bearings and carries the
oddball rare items
only as a service to their customers who might need one once every couple of

At $42, I hope you bought two sets! I can't explain the difference,
either. There are a signficant range of prices (I found a part for my
hot-tub pump ranged from $109 to $13 depending upon whom on the
internet that I bought it from).
Different companies price differently according to business model and
market conditions. Some price high and expect low volume, high
margin. Some price low and expect high volume on a low margin. Some
folks (mostly naive or overly hopeful ebay newbies) price ridiculously
high or low. Like the South Bend Heavy Ten that went a few weeks ago
for a buy-it-new price of $300.
For Timken bearings the "A" suffix means different OD/ID or roller
complement. "B" means flanged, so your lathe may use retaining rings
or a different bore/shoulder configuration I guess.
Thanks for the lead about EB Atmus. I plan to reassemble my lathe
after cleaning and and painting to see what my runout looks like
before I pop for new bearings. In case others would find it useful:
http://www.ebatmus.com/ is the link for this Springfield, Mass,
company (I have no affiliation with them).
