Long life: Fatigue life, Lubrication life, Sealing life.2. High speed performance;3. High sealing capacity;4. Excellent high & low temperature working condition;5. Low starting torque;6. Creep resistance.DESIGN STRUCTURE1. INNER RING, OUTER RING, STEEL BALL: Bearing rings manufactured with high purity special bearing quality steel;2. CAGE: Glass fibre reinforced polyamide cage;3. SEALING RINGS: 1. Inner rings with V-shaped groove; 2.Seal ring with triple-lip contact design4. GREASE: Synthetic oil (base oil)+Polturea-based (thickener) grease;5. OD with expansion nylon ring or "O" shaped rubber ringZXZ alternator bearings for automobileAlternator BearingsApplication:1. High-speed running of bearings inner ring;2.Temperature of operating environment above 120ºC;3. Surrounding of bearings with water vapor,dust;4. Contact with mud some times;5. Soak in water in special time;6. Use in high-temperature and alpine region;7. High requirement of limiting speed;8. Operate inside a magnetic field, prone to have white flaking;9. Can withstand operating conditions both of rapid acceleration and rapid deceleration.Performance:1.   The sealing performance requirements; do not allow water, vapor or dust leak into bearings;2.   Bearing requirements of high performance high speed;3.   High and low working temperature from -40ºC to 180ºC;4.   Low starting torque; the light contact seal;5.   The use of long life; in accordance with the requirements of more than 1000h.Advantage:The Material Selection of Bearings Components;1.    Rings adopted by high-purity specialty quality bearings steel;2.    Steel balls are from famous brand manufacturers; that effectively guarantee materials and processing accuracy;3.    Using glass fiber reinforced nylon cages;4.    Sealed with high quality acrylic rubber;5.    Using synthetic oil (base oil) + Polyurea (thichening agent) grease.Design Structure:1.    Sealed with tri-lips light contact structure-having supper sealing performance, and suitable for high-speed operation;2.    Using engineering plastics cages with oil reservoir structured-effectively increase the lubrication capability of bearings;3.    Optimize the groove curvature of outer ring and the raceway of inner ring-suitable for high-speed and reduce axial movement;4.    Some bearing`s OD with nylon expansion ring or [O"-type ring-prevent creeping.
