Electromechanical or Fluid Power – Which Linear Actuation Option is Best for Your Industrial System?

Linear actuation plays a critical role in a wide range of products and processes in factory automation, packaging, medical devices, and many other fields.

Linear actuators are commonly divided into two main types: fluid power actuators that operate on differential pressure and electromechanical actuators driven by an electric motor. The type of actuator used plays a critical role in the machine’s performance, initial cost and operating costs.

This article provides an honest look at the pros and cons of each of the main types of linear actuators, with the goal of providing a general guide for their selection and application.

Is there a way to predict or calculate noise on a ball screw?

SOLUTION: There is no way to calculate the noise of a ball screw, but there are ways to minimize noise in an application.

Larger ball screws utilize larger ball bearings and are therefore inherently noisier, and external return systems are inherently noisier than internal return systems.

Additionally, the use of spacer balls can reduce the noise of a ball nut. Selecting and properly applying the right grease can also reduce the overall noise level. Minimizing or eliminating backlash can also reduce overall assembly noise.
