7206CD/HC Angular Contact Ball Bearing 30×62×16mm for CNC Equipment Product Overview 7206CD/HC is single row hybrid ceramic angular contact ball bearing with 15° contact angle. It adopts GCr15 steel raceways matched with silicon nitride ceramic balls. This bearing can withstand combined radial and one-direction axial loads. Ceramic balls reduce centrifugal force under high-speed operation, lower heat build-up and block electric current to prevent electric corrosion, perfectly
