For individual balls used in this kind of bearing that are sometimes incorrectly called “ball bearings” themselves, see Ball (bearing). Working principle for a ball bearing; red dots show direction of rotation. A 4-point angular contact ball bearing A ball bearing…
 Hybrid ball bearings using ceramic balls

Hybrid ball bearings using ceramic balls

Ceramic bearing balls can weigh up to 40% less than steel ones, depending on size and material. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate 20% to 40% faster than conventional bearings. This means that the…

Fully ceramic bearings

These bearings make use of both ceramic balls and race. These bearings are impervious to corrosion and rarely require lubrication if at all. Due to the stiffness and hardness of the balls and race these bearings are noisy at high…

Riding with friend is the best feeling in the world

Most bearings are meant for supporting loads perpendicular to axle (“radial loads”). Whether they can also bear axial loads, and if so, how much, depends on the type of bearing. Thrust bearings (commonly found on lazy susans) are specifically designed for axial loads…
