Vmc Systems Mechanical Engineer Interview Questions and Answers

The bearing types used in axially split centrifugal pumps are mainly ball bearings and sleeve bearings.

• Ball bearings are commonly used in axially split centrifugal pumps due to their high load capacity and low friction.

• Sleeve bearings, also known as journal bearings, are used in pumps that operate at lower speeds and lower loads.

• Other types of bearings, such as roller bearings, may also be used depending on the specifi
