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.

Hybrid ceramic ball bearings, thanks to their unique material properties, have been widely used in a variety of high-tech fields:

-1-  Aerospace

Under high-speed, high-temperature environments, the lightweight (density is only 40% of steel) and high-temperature stability (withstands 1000°C) of silicon nitride ceramic balls significantly improve the reliability and lifespan of aircraft propulsion systems.

-2- New Energy Vehicles

Suitable for motor bearings, their low density reduces centrifugal force and improves speed performance; their insulation properties prevent galvanic corrosion and extend the lifespan of electric drive systems.

-3- Precision Medical Equipment

In MRI equipment, the insulation and low magnetic loss of ceramic balls ensure imaging accuracy; surgical robot joints rely on their high wear resistance to achieve millions of precise movements.

-4- Semiconductors and Vacuum Equipment

Silicon nitride's corrosion resistance and lubrication-free self-lubricating properties make it a key component in vacuum pumps and chip manufacturing equipment.

-5- Wind Power and Industrial Robots

Stable performance remains stable in extreme temperatures (-60°C to 800°C), adapting to the low-temperature environments of wind turbine towers and the high-load scenarios of industrial robots.

-6- High-speed, low-noise equipment

For precision instruments or high-speed motors, optimizing surface precision reduces operating noise while also providing insulation to prevent spark interference.

Extended service life 

TKW hybrid bearings provide superior grease  life, especially in situations with difficult operating conditions. 

Small to medium sized sealed TKW hybrid  deep groove ball bearings are lubricated with  TKW electric motor grease. Tests have shown  that these bearings provide a longer service  life than all-steel bearings. 

What is Hybrid Bearings and Why Hybrid bearings?

Hybrid angular contact ball bearings (designation suffix HC, Or the other suffix) 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
