  • Is there a way to predict/calculate noise on a ball screw? A: No, there is no way to calculate the noise of a ball screw. There are ways to minimize the noise of an application though. Larger ball screws utilize larger ball bearings and are therefore inherently noisier. External return systems are also inherently noisier than internal return system. The use of spacer balls can reduce the noise of a ball nut. The selection and proper application of grease can also reduce the overall noise level.

  • A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. The inlet is not walled off from the outlet as is the case with positive dis- placement pumps,whether they are reciprocating or rotary in configuration. Rather, a cen- trifugal pump delivers useful energy to the fluid or “pumpage” largely through velocity changes that occur as this fluid flows through the impeller and the associated fixed pas- sageways of the pump; that is, it is a “rotodynamic” pump.

  • Rolling-element bearings, such as ball, cylindrical, or conical rolling bearings, are the bearings most widely used in machinery. Rolling bearings are often referred to as antifriction bearings. The most important advantage of rolling-element bearings is the low friction and wear of rolling relative to that of sliding.
