Conical Metal Pivots for Sapphire and Glass Vee Bearing
Jewel Bearings
Vee bearings are available in sapphire, ruby, hard Pyrex glass and tungsten carbide materials.
Vee and cup type jewel bearings afford one of the lowest coefficient of friction in the miniature instrument bearing field. (Approximately 0.12 steel on sapphire) Several reasons account for this. Foremost, vee bearings provide point contact with the moving shaft element. Other miniature bearing types have line contact. Secondarily, the sapphire and glass materials offer low elastic deformation characteristics.
