General Aptitude question

Q1. What is bearing and types?
Ans. 
Bearings are mechanical components that allow for smooth rotation or linear motion between two parts.
• Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to reduce friction between two surfaces.

• Roller bearings use cylindrical rollers to support radial and axial loads.

• Plain bearings have a sliding surface instead of balls or rollers.

• Fluid bearings use a thi...read more
