Rolling bearings: Invisible heroes of everyday life – how they work and areas of application
Rolling bearings - we encounter these inconspicuous machine elements every day without being aware of their importance. From brushing your teeth in the morning with an electric toothbrush to driving to work in a car to generating electricity using wind turbines: rolling bearings are used wherever something rotates.
This blog post, the first in our series on rolling bearings, delves into the fascinating world of these little heroes and sheds light on how they work, where they are used and how they matter for our modern world.
What is a rolling bearing? Structure and function!
A rolling bearing is a machine element that enables a low-friction and flexible connection between two components, such as a shaft and a housing. It ensures efficient load transfer and thus enables the desired movement. The main components of a rolling bearing are:
Inner ring: Sits on the shaft and rotates with it.
Outer ring: Sits in the housing and is usually fixed.
Rolling elements: Balls or rollers located between the inner and outer rings that transfer the load.
Cage: Keeps the rolling elements at an equal distance and prevents them from touching.
Rolling bearing types: ball bearings & roller bearings
Rolling bearings can be divided into two main types:
Ball bearings: Suitable for high speeds and low to medium loads. Examples: deep groove ball bearings, angular contact ball bearings.
Roller bearings: Suitable for high loads and shock loads. Examples: cylindrical roller bearings, tapered roller bearings, needle bearings.
The choice of the right type of rolling bearing depends on various factors such as load, speed, operating temperature and installation conditions.
Wide range of applications for rolling bearings
The possible uses of rolling bearings are almost unlimited. They can be found in countless applications, including:
Mobility: cars, planes, trains, bicycles, motorcycles, etc.
Energy generation: wind turbines, hydroelectric power plants, generators, etc.
Industry: machine tools, robots, conveyor systems, pumps, compressors, etc.
Household appliances: washing machines, vacuum cleaners, refrigerators, etc.
Sports & Leisure: Bicycles, inline skates, fitness equipment, etc.
