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.

PROBLEM:
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.
