I'm trying to determine load ratings for a deep groove roller bearing for use in a roller skate. I suspect I'll be looking at 100kg x 9.8N / 4 (2 bearings per wheel, likely only every to have a single set of wheels, front or back - 4 bearings - on the ground) * 2 (but this could be a landing!) for the Radial and I *think* Axial load should be 25% of that rating. Any thoughts? Thanks in advance!
