Pallolaakeri

Pallolaakeri is a Finnish term that translates to "ball bearing" in English. It refers to a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support loads.

Ball bearings are commonly found in a wide range of applications, from everyday items like inline skates and bicycles to industrial machinery and automotive components. Their design allows for relatively low friction movement, making them efficient for transmitting power and supporting rotational motion. The balls are typically made of hardened steel, ceramic, or other durable materials.

The basic structure of a ball bearing consists of an inner ring, an outer ring, the balls themselves, and a cage that keeps the balls evenly spaced. The specific configuration and materials used can vary depending on the intended application and the types of loads the bearing is expected to handle. Different types of ball bearings exist, including deep groove ball bearings, angular contact ball bearings, and self-aligning ball bearings, each designed for specific performance characteristics and load conditions. Regular maintenance, such as lubrication, is often necessary to ensure the longevity and optimal performance of pallolaakerit.
