Sales Executive Engineer Interview Questions and Answers

For heavy loads, roller bearings are typically used due to their ability to support higher loads.

• Roller bearings are commonly used for heavy loads due to their larger contact area compared to ball bearings

• Types of roller bearings include cylindrical, spherical, and tapered roller bearings

• Examples of heavy load applications include industrial machinery, construction equipment, and automotive components

Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings: use balls to reduce friction between two surfaces (e.g. deep groove ball bearings)

• Roller bearings: use cylindrical rollers to reduce friction (e.g. tapered roller bearings)

• Plain bearings: use a sliding surface to reduce friction (e.g. bushings)

• Fluid bearings: use a fluid film to reduce friction (e.g. hydrodynamic bearings)
