The front bearing on my TS Arbor is labeled as 6202RS. When I Google that
number I get tons of hits for 6002-2RS. Many pages use both numbers for
the same part. Is there a difference?

One example is this listing on eBay which lists the model number as 6202-2RS
but uses 6202RS in the detailed description. Even the link uses both 6202-2rs
and 6202rs.
