Rolling Bearings: Invisible Heroes of Everyday Life - Functionality & Areas of Application
Rolling bearings - these inconspicuous machine elements encounter us daily, without us being aware of their significance. From brushing our teeth in the morning with an electric toothbrush to the commute to work in a car, and even to electricity generation through wind turbines: rolling bearings are in use wherever something rotates.
This blog post, the first in our series on rolling bearings, dives into the fascinating world of these little heroes and highlights their functionality, applications, and significance for our modern world.
What is a rolling bearing? Structure & Functionality!
A rolling bearing is a machine element that enables a low-friction and movable connection between two components, such as a shaft and a housing. It ensures efficient load transfer and thus allows the desired movement. The main components of a rolling bearing are:
- Inner ring: Sits on the wave and spins with it.
- Outer ring: Sits in the housing and is usually fixed.
- Rolling elements: Balls or rollers that are located between the inner and outer rings and transmit the load.
- Cage: Hält die Wälzkörper in gleichmäßigem Abstand und verhindert deren Berührung.
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 bearing: 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.
Diverse Applications of Rolling Bearings
The applications of rolling bearings are virtually limitless. They can be found in countless applications, including:
- Mobility: cars, airplanes, trains, bicycles, motorcycles, etc.
- Energy generation: Wind turbines, hydropower plants, generators, etc.
- Industry: Machine tools, robots, conveyor systems, pumps, compressors, etc.
- Household appliances: Washing machines, vacuum cleaners, refrigerators, etc.
- Sport & Leisure: Bicycles, inline skates, fitness equipment, etc.
