SNL Bearings Interview Questions, Process, and Tips

Gearbox is a mechanical device that transmits power from an engine to the wheels.

• Understand the gear ratios and their corresponding speeds

• Use the clutch to engage and disengage gears

• Shift gears smoothly and at the appropriate time

• Maintain the gearbox regularly to ensure proper functioning

There are several types of bearings used in production engineering.

• Plain bearings

• Rolling element bearings

• Jewel bearings

• Fluid bearings

• Magnetic bearings

• Flexure bearings

Bearings are used to reduce friction between two moving parts and to support loads.

• Bearings are used in machines and equipment such as motors, pumps, and turbines.

• They are used to support rotating shafts and to reduce friction between moving parts.

• Bearings can be classified into different types such as ball bearings, roller bearings, and plain bearings.

• Ball bearings are used in applications where high speed and low fri...read more

Four stroke engines have four distinct phases while two stroke engines have only two phases.

• Four stroke engines have separate intake, compression, power, and exhaust strokes.

• Two stroke engines combine intake and compression in one stroke, and power and exhaust in another stroke.

• Four stroke engines are more fuel efficient and produce less pollution compared to two stroke engines.

• Examples of four stroke engines include m...read more

Diesel engines are more fuel-efficient and have higher torque, while petrol engines have higher power output and are more responsive.

• Diesel engines use compression ignition while petrol engines use spark ignition.

• Diesel engines have a higher compression ratio than petrol engines.

• Diesel engines are more suitable for heavy-duty vehicles while petrol engines are more suitable for light-duty vehicles.

• Diesel engines produce...read more
