Key Considerations that Impact the Selection of Electric Liner Actuators November 30, Right from automatic windows and cupboards to heavy-duty conveyors and fork lifts, electric linear actuators play a crucial role. Here are some basic yet critical considerations to consider before making a purchasing decision.

Are you interested in knowing more? Read the following post to understand complete knowledge of heavy duty linear actuators.

Ball Screw Assembly Capabilities: No standard ball screw can satisfy every application requirement. If you have any questions about the suitability of the current Beaver applications, don’t hesitate to call us.

October 14, One of the major application of linear actuators is conveyor system. The conveyor belts make use of linear actuators for material handling requirements. This post will discuss in detail the use of linear actuator in the conveyors. How Do They Differ? October 5, Acme lead screws and ball screws are two of the most effective lead screws used today.


What makes them different? How do they add value to equipment or systems? This post answers all these questions. September 15, Linear actuators provide accurate motion control in diverse applications, such as test equipment, assembly machinery, medical equipment, etc.

Electric linear actuators are one of the common linear actuators, which are known to provide highest precision-control positioning.

Ball Screw Assembly Capabilities

September 1, The demand for actuator driven devices in agricultural sector has increased. Actuators are designed to withstand rough weather conditions, environmental bumps and exposure to all sorts of fertilizers.

This post discusses about how actuators are adding value in various types of farming equipment. What are the different accessories of the 5th wheel landing gears? Read on the following post to get knowledge about different accessories that are important for the proper functioning of a landing gear.

How are Electric Linear Actuators Important for Solar Tracker System August 1, There are several advantages of using an electric actuator in a solar tracking system, some of which are as given in this post.

What are solar trackers? How do they work?

The terms form and threadform sometimes refer to all design aspects taken together cross-sectional shape, pitch, and diameters. In We're the Millers Rose quits her job as a stripper when her boss wants her to start having sex with the customers. These are usually called V-threads or vee-threads because of the shape of the letter V. The axle nuts, or less commonly, lug nuts on the left side of some automobiles.

Why are linear actuators important in solar tracking systems? These questions are also answered in this post. They play a vital role in several applications and are widely used to make the job easier.

A ball bearing screw is just that: a screw which runs on ball bearings. The screw and nut have matching helical grooves or races, and the ball bearings recirculate in these races.

June 20, The 12 volt linear actuators provide excellent repeatability and precision. Here is how these actuators can provide efficient performance, as well as cost benefits.

This post discusses five such linear actuator driven agricultural applications.

Guide to Working of Electric Linear Actuators December 5, Would you like to know in detail the exact working of these extremely popular actuators? Slaves are made in such ways!

Why are Actuators Important in Dental Chairs? Therefore, it is not necessary to multiply the stroke length by 2 as was required in the vertical application.

Using the same example presented for the vertical application, the calculation to determine the design life objective would instead be: The three factors that determine the safe speed of a ball bearing screw are the screw diameter, the screw length and the rigidity of the end mountings end fixity.

The critical speed formula will help you ensure that the model you have selected will operate safely within your speed requirements. If a sufficiently heavy load is applied to a long ball bearing screw it could buckle.

The three factors that determine a safe compression load are: The compression load formula on page 20 will allow you to verify that your selection meets safe compression load requirements.

There's nothing you can do about it, and it doesn't go away; your only choice is to turn your controller upside down and book it out of there. Lead error is cumulative based on the actual length of the ballscrew thread. Prior to its introduction, a rope drum drive controlled the rudder.

Excessive compression and tension loads should be avoided. Click here to view Mounting Requirements. LEAD You must determine what lead will be most appropriate for your application. The lead is the distance the nut will travel with one revolution of the ballscrew. Smaller leads will make the nut travel slower over the length of the screw for a given RPM while a larger lead will allow the nut to travel faster over the length of the screw at the same RPM.

The most commonly utilized inch leads are.

Lead Screw vs. Ball Screw Technology

The most common metric leads are 5mm and 10mm. The lead accuracy of a ballscrew is a measure of the cumulative lead error per foot. Units can also be supplied to ISO classes 1, 5, 7 and 9.
