Pallolaakereihin, often translated as ball bearings, are a type of rolling-element bearing. They are designed to reduce rotational friction and support axial loads. A ball bearing consists of an inner ring, an outer ring, balls, and a cage. The balls are placed between the inner and outer rings, allowing them to roll freely and minimize friction. The cage separates the balls, preventing them from rubbing against each other and ensuring smooth operation.

Ball bearings are widely used in many applications due to their efficiency and versatility. Common examples include automotive wheels, electric motors, bicycles, and industrial machinery. They are favored for their ability to handle moderate loads and high speeds. The design of a ball bearing can vary depending on the specific requirements of its application. For instance, deep groove ball bearings are the most common type, suitable for both radial and axial loads. Angular contact ball bearings are designed to handle combined loads, while thrust ball bearings are specifically for axial loads.

The proper functioning and longevity of ball bearings depend on factors such as lubrication, cleanliness, and correct installation. Contamination by dust or debris can significantly reduce their lifespan. Regular maintenance and appropriate lubrication are crucial for optimal performance. The development of ball bearing technology has played a vital role in the advancement of mechanical engineering and continues to be an essential component in countless machines and devices.
