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.

Super-precision angular contact ball bearings includes bearings in the following dimension series:

• Ultra light 718 series    • Extremely light 719 series     • Light 70 series       • Robust 72 series

Application of High Speed Bearing 71802 CD/HCP4

These super-precision, high-capacity, single row angular contact ball bearings accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures. Being universally matchable, they can be used together in arrangements to provide effective load sharing, within a predetermined preload range, without the use of shims or similar devices.

• Very high running accuracy

• Very high load carrying capacity

• Relatively high speed and stiffness

• Universally matchable
