Better bearings?
I'm looking for bearing recommendations and suppliers.
I've been using in-line/skateboard bearings for my projects. They spin great, are easy to source and cheap.
The difference in spin among brands/ratings are significant. An ABEC 1 is poor. An ABEC 7 is much better. But even 2 different brands of ABEC 7 will spin differently.
The BEST is Bones Swiss!
However, the bore size of skate bearings is small (ID- inner dimension): 8mm (about 5/16")
Now I'm looking for a bore size of 1/2" or 5/8".
I've tried a number of other bearings: pillow blocks, flange, trailer hubs, insert and needle.
On a scale of 1 to 10, Bones Swiss is a 10, ABEC 7 is a 7, then all these others are like a 2.
They are packed in heavy grease and are designed mostly for being driven by large horsepower.
So I'm looking for bearings with spin like the Bones Swiss - but have a bore size of like 1/2" or 5/8".
I get most of my stuff from:
MSC: http://www1.mscdirect.com/CGI/NNSRHM
and
Grainger: http://www.grainger.com/Grainger/wwg/start.shtml
and super priced pillow blocks etc. from
http://www.thebigbearingstore.com
Without having a bearing in my hand to spin - I don't know how it performs.
What bearings should I use?
Any bearings suit the bill from the links I gave?
Any other US supplier links?
What bearings have YOU had success with and recommend?
Comments?
Thanks!
