Description

HYBRID BALL BEARINGS Ball bearings with a material combination of bearing steel (inner and outer rings) and ceramic (balls) are called ‘hybrid’ ball bearings. All ball bearings can be supplied as hybrid ball bearings. ADVANTAGES OF HYBRID BALL BEARINGS LONG LIFE Due to their characteristic material properties, hybrid ball bearings last more than twice as long as steel bearings. Machine run times are significantly increased. HIGH RPM’S Due to their tribological properties and lower mass forces – compared to bearings with steel balls – speed increases of up to 30 % can be achieved with hybrid ball bearings. LOWER-COST LUBRICATION The maximum RPM for grease and oil lubrication is increased. Thus hybrid ball bearings can frequently use grease lubrication instead of more expensive oil lubrication. HIGHER PROCESSING EFFICIENCY The higher bearing rigidity, reduced thermal expansion and lower vibration excitation of hybrid ball bearings ensure maximum machining accuracy. GREATER STIFFNESS General radial and axial stiffness increases due to the material characteristics of hybrid ball bearings. The benefits are increased precision and displacement at critical own frequencies. APPLICATION EXAMPLES FOR HYBRID BALL BEARINGS _Machine tool spindles _Fast running machine bearings _Durability-optimized precision bearings
