Why Ceramic? Why World Wide Bearings?
Each bearing is made in house at World Wide by hand, assembled from only the best components available on the market.
These ceramic bearings can reduce rolling friction by up to 40% over traditional steel bearings, typically last approximately twice as long before needing replacement, and reduce rotating weight by up to 60% per bearing.
With high-grade balls and cages utilized, runout on Worldwide Bearings is minimized, reducing heat generated internally in the bearing.
