7205CD/HC Hybrid Ceramic Angular Contact Ball Bearing 25×52×15mm for High Frequency Motor

• 7205CD/HC is single row hybrid ceramic angular contact ball bearing with 15° contact angle. It uses steel raceways paired with silicon nitride ceramic balls. The bearing can bear combined radial and one-direction axial loads. Ceramic balls greatly reduce centrifugal force at high speed, cut heat generation and prevent electric corrosion, ideal for high-precision high-speed rotating systems.
