I'm building an engraving spindle using a high speed bldc motor made
for a model airplane. Today I'll be testing the first iteration at
about 14,400 rpm. This is the highest speed my motors will go. If the
test goes OK I'll be buying higher speed motors and will need
bearings. My plan is to use ER8 collets in an ER8 holder that has a
10mm OD. So the ER8 holder will be the spindle. Which means the
bearings will have a 10mm ID and a max OD of 30mm in order to fit into
the spindle housing which will fit into a 1.5 ID tool holder. I think
what I want is a couple deep groove bearings. The axial and radial
loads will be small but the RPM so high that the dynamic load may be
high. I will try using the load calculator at the SKF website but
would also appreciate advice from folks here who do this kind of thing
and can steer me in the right direction. Even though the SKF website
has all sorts of great info I have been unable to find an SKF ball
bearing catalog online. I need this in order to plug the right SKF
part number into the bearing calculator.
Thanks,
Eric

I think you can't be looking very hard on the SKF site as I've always
been able to find the technical information for bearings quite easily.
From Dan's suggestion of a 6200 here is the shielded version

Greetings David,
I spent over an hour last night looking for specific bearings on the
SKF website. I must be blind or stupid because you found it right off.
I was looking for a bearing catalog. I see I should have been looking
at the product tables.
Thanks,
Eric
