A study on plastic rolling bearings (Coefficient of friction of plastic ball bearings)

摘要

The precision of products in plastic rolling bearings has been significantly improved by advances in molding technology and assembly technology. However, the idea that these bearings are still used only as miscellaneous mechanical parts is one of the problems that has not yet been wiped away. The reason why reliability has not yet been recognized is the lack of detailed reports about the character- istics of these bearings capable of supporting designs as data.
