What is Hybrid Bearings and Why Hybrid bearings?
Hybrid angular contact ball bearings (designation suffix HC) have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (ceramic). As ceramic balls are lighter and have a higher modulus of elasticity and lower coefficient of thermal expansion than steel balls, hybrid bearings can provide the following advantages:
• higher degree of rigidity
• higher speed capability
• reduced centrifugal and inertial forces within the bearing
• minimized stress at the outer ring rolling contacts at high speeds
• reduced frictional heat • less energy consumption
• extended bearing and grease service life
• less prone to skid smearing damage and cage damage when subject to frequent rapid starts and stops
• less sensitive to temperature differences within the bearing
• more accurate preload/clearance control
