Roller Bearing

Thanks to ThinkingandTinkering (https://www.thingiverse.com/thing:6898888) for the idea of a cylinder bearing and the profound explanation in the linked video on how to create in Tinkercad, very appreciated.

Some viewers of the video found serious wear when using the model. The wear is caused by the cone-shaped surface of the raceways and the cylindrical-shaped surface of the roller. They don’t match well.

This model here uses cone-shaped rollers that match the cone-shape of the raceway. As in the above referenced model, the rollers may be positioned in two ways which are roughly 90 degrees apart. The larger diameter of the roller always points to the outside of the race.

This model is more of a proof of concept than a ready to use mechanical part.

The following parts are needed:

* 10 (identical) rollers
* 2 (identical) races
* 1 cage
* 1 fixture (optional and intended when used without cage)

The geometry was designed with sketchometry. Many thanks to the Universität of Bayreu
