RE: [CAD_CAM_EDM_DRO] angular contact bearings for mill/drill ballscrews

Hi Dan

You can buy ABEC-1 angulars...$20-$40 or so. They are not that common,
but MSC has them.

TIMKEN tapered roller bearing can also be used if the rpm is low...also
cheap.

Subject: [CAD_CAM_EDM_DRO] angular contact bearings for mill/drill
ballscrews


I am reworking my CNC'd mill/drill. I set it up over 5 years ago and have
learned a lot
since then. I never did replace the thrust bearings for the X and Y
ballscrews. My mill still
has the originals- balls captured by a stamped steel retainer that are
purely for thrust. I
would like to replace them so that they can handle some side load (mainly
from timing
belt mounted motor arrangement). My day job has me sometimes sourcing
ballscrew
bearings for real machine tools (Barden matched sets @ $375 a set) and I
know I can't
afford the 'real thing'. I am interested in angular contact bearings that
are affordable.

I did a quick search through this list and DIY_CNC and didn't run across
any references to
this. So... What are people using for replacing the bearings on the endcaps
on these mill/
drills?

Thanks,

Dan
