  • How can different materials affect bearing

    2019-3-12 · Ceramic ball bearings can be around 60% lighter, 120% harder and around 70% stiffer than their steel counterparts, while still achieving a much higher temperature rating of over 700°C. Ceramic balls also require less lubrication – often being capable of lubrication-free operation – offer lower friction levels and remain cool at high speeds.
