All about bearings
The concept of using a bearing to reduce friction between an object and the surface over which it is moved – or to “bear” the burden – is almost as old as man himself.
What is a Bearing?
A bearing is a mechanical element that supports rotating or moving parts and helps reduce friction between them. It allows for constrained motion—usually rotation or linear movement—between two surfaces while carrying radial, axial, or combined loads.
Rolling Through Time: A Brief History of Bearings.
The concept of bearings dates back thousands of years. Ancient Egyptians used rolling logs to move heavy stones during pyramid construction—an early form of reducing friction. In the 15th century, Leonardo da Vinci sketched the first known design of a ball bearing for rotating systems.
Modern bearing development began in the 18th and 19th centuries, especially during the Industrial Revolution, when machines required smoother and more efficient rotational movement. In 1794, Philip Vaughan, a Welsh inventor, patented the first recorded ball bearing design. As metallurgy and manufacturing techniques advanced, so did bearing performance and precision.
How Do Bearings Work?
Bearings work by placing rolling elements (balls or rollers) between two surfaces—the inner and outer raceways—allowing smooth motion with minimal friction. As the inner ring rotates, the rolling elements reduce contact between surfaces, enabling efficient rotation and load distribution. Lubrication (oil or grease) is often used to minimize wear and heat generation.
BEARINGS ELEMENTS
1. Inner Ring
Mounted on the rotating shaft.
Rotates along with the shaft and provides a raceway for rolling elements.
2. Outer Ring
Fixed inside the housing.
Provides a raceway for the rolling elements and remains stationary.
3. Rolling Elements
Balls or rollers placed between the inner and outer rings.
Allow smooth rotation by reducing contact surface and friction.
4. Cage (Retainer)
Holds rolling elements at equal distances.
Prevents them from rubbing against each other and ensures even load distribution.
5. Seals/Shields
Protect the bearing from contaminants like dust, dirt, and moisture.
Help retain lubrication inside the bearing.
