NRB Bearings Program Manager Interview Questions and Answers

Bearing types include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearings use cylindrical, tapered, or spherical rollers to reduce friction and support radial and axial loads.

• Plain bearings have a sliding surface and are used for low-speed, high-load applications.

• Fluid bearings use a thin layer of fluid to suppo...read more

The tolerance range for bearings depends on the type and application of the bearing.

• Tolerance range is the acceptable deviation from the specified dimension or value.

• For example, the tolerance range for a ball bearing used in a high-speed application will be smaller than that of a bearing used in a low-speed application.

• Factors such as load, speed, temperature, and lubrication also affect the tolerance range.

• Manufactur...read more
