Balkrishna Industries Mechanical Shift Engineer Interview Questions and Answers

Bearing is a machine element that allows one part to bear another part's weight and facilitate relative motion between the two parts.

• Bearing is used to support rotating shafts in machinery.

• It reduces friction between moving parts.

• Common types include ball bearings, roller bearings, and plain bearings.

• Examples: wheel bearings in cars, bearings in electric motors.

The strongest bearings are typically made of materials like steel, ceramic, or titanium for high durability and load capacity.

• Steel bearings are commonly used for their strength and durability.

• Ceramic bearings are known for their high resistance to corrosion and wear.

• Titanium bearings are lightweight yet strong, making them ideal for certain applications.

There are three main types of maintenance: preventive, predictive, and corrective.

• Preventive maintenance involves regularly scheduled inspections and maintenance to prevent breakdowns.

• Predictive maintenance uses data and analytics to predict when equipment will fail and perform maintenance before it happens.

• Corrective maintenance is done after a breakdown occurs to restore equipment to working condition.

• Examples: Chang...read more

Preventive maintenance involves regularly scheduled inspections, repairs, and replacements to prevent equipment breakdowns.

• Regularly inspecting equipment for signs of wear and tear

• Replacing worn out parts before they fail

• Cleaning and lubricating machinery to prevent corrosion and friction

• Creating a maintenance schedule based on manufacturer recommendations

• Using predictive maintenance techniques such as vibration analys...read more

There are various types of bearings used in mechanical systems, each with specific uses such as reducing friction and supporting loads.

• Ball bearings: used for low friction applications like wheels and conveyor belts

• Roller bearings: used for heavy radial loads like in car transmissions

• Thrust bearings: used for axial loads like in propellers

• Plain bearings: used for high load capacity and shock resistance like in cranksha

A compressor works by increasing the pressure of a gas to compress it into a smaller volume.

• Compressors use a motor to drive a piston or rotor that compresses the gas.

• The compressed gas is then stored in a tank or released for use in various applications.

• Common types of compressors include reciprocating, rotary screw, and centrifugal compressors.
