• What's the difference between repeatability and accuracy in linear motion systems?

  Accurate and repeatable,often used interchangeably.When someone says a ball screw is very accurate,they may really mean it is repeatable.In fact,accuracy and repeatability are unrelated.A system can be very accurate,but not very repeatable,and vice versa.Here's the difference:Accurate,but not repeat

• What are the types of ball screw seals?

  In most applications,the best way to protect ball screws from contamination is to use ball screw wiper on each end of the ballnut.Manufacturers use different terms to describe the various ball screw sealing options,but most offer 3 basic types of seals:non-contact,full-contact and high performance v

• What are methods for inducing preload in a double ballnut？

  A double ballnut is essentially two single ballnuts that are tensioned against each other to induce preload.The three common methods of inducing preload in a double ballnut are：

• What are the recirculation ways of ball screws?

  Ball Screws are available in four different ball-recirculation options including tube,deflector,end-cap and end-deflector ball-recirculation designs.●Tube-type recirculation ball screw The standard and most economical option is tube-type recirculation.The ball is recirculated through the ball return

• What should you consider when mounting linear guides?

  Linear guides are designed for applications that require precise motion with high load bearing capacity.However,improper mounting can add unnecessary load,shorten service life,and destroy the inherent travel accuracy of a linear guide system.Understanding and following the three mounting specificati

• How to avoid ball screw buckling?

  Determining the buckling load is an important step in ball screw selection.The buckling(compression)load can be easily calculated based on the root diameter of the screw,the overhead length and the end bearing configuration. Where:Fc=maximum compressive load(N)fb =end bearing factord1=root diameter

• What is the difference between plain and rolling linear guide?

  A linear guide(or linear bearing)is a mechanical element that allows for relative motion between two surfaces,with one surface supporting the other and with minimal friction between the two.There are two basic types of linear guides:plain and rolling element.While their general function is the same,

• What may make your ball screw failure?

  The ball screw must be mounted in such a way as to ensure proper alignment with the guidance system to avoid bending moments and binding during travel.

• ​What factors should not be ignored when choosing a linear system?

  When choosing a linear system,the first application parameters that come to mind are likely to be travel,load and speed.In addition,detailed information on load placement,move profiles and duty cycles are needed to accurately calculate bearing life,which are typical criteria for evaluating a linear
