CERAMIC BALLS 

Ceramic hybrid bearings deliver advanced performance  characteristics that can be transformational in machine tools. TKW offers silicon nitride (Si3N4) ceramic balls as a standard option  for angular contact ball bearings to achieve ultra-high machining  speeds, in addition to a considerable array of advantages: 

› Higher rigidity and rotational accuracy, enabling high-accuracy  machining 

› Lower sliding friction in high-speed applications 

› Lower heat generation

› Higher seizure resistance 

› Longer grease life due to low heat generation.

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
