PurPose of Bearings

The main purpose of bearings is to prevent friction, heat generation and ultimately, the wear and tear of parts.

• It also reduces energy consumption as sliding motion is replaced with low friction rolling.

• They also transmit the load of the rotating element to the housing.

rolling element Bearings

• Rolling element bearings contain rolling elements in the shape of balls or cylinders. Rolling element bearings are used to facilitate the free movement of parts in rotational motion. Even when we need linear motion in applications, it is easy to convert rotational motion to sliding motion.

Ball Bearings

• Ball bearings are one of the most common types of bearing classes used. It consists of a row of balls as rolling elements.

Very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races.

of Ball Bearings

wear resistance

not need much lubrication

low friction, thus little energy loss

DisaDVantages

May break due to shocks

Can be quite loud

Cannot handle large weights

WHen to use Ball Bearings?

•Some of working conditions that require ball bearing.

Thrust loads are present. Ball bearings’ design makes them capable of withstanding axial loads.

No heavy loads. Due to having ball-shaped rolling elements, the bearings concentrate all the force onto a few points of contact. This can result in early failure with high loads.

High speeds. The ball bearing’s small point of contact also means less friction. So there is less resistance to overcome and thus it is easier to achieve high speeds with these types of bearings.
