Ceramic Hybrid Ball Bearings utilize Silicon Nitride balls with steel inner and outer rings. These hybrids out perform traditional steel bearings in many ways. They eliminate electrical arcing or fluting. Bearing service life is two to five times longer as the ceramic balls exhibit reduced surface and adhesive wear. Running speeds can be up to 50% higher while providing higher upper end temperature limits. The higher modulus of elasticity also improves spindle rigidity which improves vibration characteristics and performance. Recommended applications include: Machine Tools, Electric Motors and Generators, Traction motors, Woodworking machinery, Food Processing, Centrifuges, X Ray tubes and Robotics.
