I purchased some bearings from McMaster.
While waiting for the bearings I searched out a company Igus and ordered some pillow blocks.
Ends up that the bearings I ordered from McMaster was also from Igus!
I went with the ESTM-20 20mm pillow block.
Good for long term axial loading of 155lbs, and short term 315 lbs.
Needs spacers for mounting holes and adapter to fit cable.
