Ceramic bearings for high speed.

Bearing design is a critical part of today's high-speed machine tools. Traditionally, spindle manufacturers use a small ball configuration, a modified internal design, and oil/air lubrication to spe up the spindle. on the other hand lately, they have been using hybrid ceramic bearings.

Machine tool spindles sporting hybrid bearings with ceramic balls have significant performance advantages above traditional steel ball bearings. According to ceramic bearing makers, spindles reach make hastes up to 40% faster and last longer because of the hybrid bearing's cooler operating temperatures. Hybrid
