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.

ADVANTAGES OF BALL BEARINGS

• Good wear resistance
• Do not need much lubrication
• Provide low friction, thus little energy loss
• Long service life
• Easy to replace
• Small general dimensions
• Comparatively cheap
• Can handle thrust loads

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 bearings 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.
