Notes

The spiral bearing design by open source Chris Log (based on a proprietary design) can be engineered for different force specifications. If we can replace a $30 bronze sleeve bearing, that means $600 savings for the drive system right in the bearings. Note that Plastic Gears are the Future, and likewise, high performance, high temperature plastics can go far in replacing metal counterparts. Plastic is 10x weaker than steel, but still - 5-10 ksi compressive strength of plastic is not insignificant.

It is useful to develop 8, 25, 50, and 75 mm versions (8 mm to 3" shaft) of these bushings for rapid prototyping, and possible applications even in tractor drive applications.
