Bearing loads for roller skates or skateboards

[adamjbradley]

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!

Shock loading will be significant for jumps with hard landings .

That will do for the static load but the dynamic load can be much, much greater:



(your units don't make sense by the way, the 9.8N should be 9.8 m/s² )
