The history of bearings goes back centuries.A bearing is a component used in a machine to facilitate motion and reduce friction in moving parts. It is designed to provide free linear motion or rotation about a fixed axis.
Classification, ossification depends on the type of surgery, the movement required and the force applied.
The simplest classification is a plain bearing consisting of a shaft rotating in a bore. The most widely known bearing is the ball bearing, which uses jumps in the timing ring to allow smooth movement at a prescribed speed.
The invention of rolling bearings dates back centuries. The first form is a wooden roller that supports the motion of an object, better known as a wheel.
Bearings have become an integral part of
Bearings have been an integral part of the first industrial revolution, keeping machines running efficiently.
The first plain and rolling bearings were made of wood.
Throughout its history, it has been made of various materials viz. Ceramics, sapphire, glass, steel, etc., as well as plastics widely used today.
Ordinary sapphire bearings are mainly used by watchmakers who produce jewelry watches. It reduces friction, which is more precise in terms of timekeeping.
Wooden bearings, although uncommon, are still used in old clocks and water mills.History of Bearings
Today, ball and roller bearings are used in a variety of industrial applications, including rotating parts. For example, ultra-high speed bearings for dental drills, gearbox and wheel bearings in the automotive industry, flex bearings in optical alignment mechanisms, bicycle hubs, etc.
