Lead Screw Parameter


A broad range of lead nuts are available,other nut type or size can be made upon drawing


When selecting the right nut for an application,there are a few things to keep in mind.Bronze nuts provide superior service at high working loads.They should be well lubricated with a good quality,Extreme Pressure(EP)grease compatible with the operating environment.Plastic nuts can be used without lubrication and are popular for low load applications.

Comparison Between Lead Screw And Ball Screw

1.Features and advantages:compared with ball screw,lead screw cost is lower,from the material,nut specification and shape,lead screw diameter and lead in the design modification more diversity,to meet customer needs.


2.Vibration and noise:The lead screw is made of various wear-resistant,temperature-resistant,self-lubricating,maintenance-free materials,long-life composite engineering plastics and anti-backlash nuts.Lead screw will not cause vibration,noise is lower than ball screw.


3.Operating environment requirements:Lead screw assemblies are less stringent to dust contamination through surface treatment and the use of engineering plastic nuts than ball screws.


4.Structure and weight:lead screws use a variety of structural styles and material nuts,so that the design structure and weight of nuts are light and easy to install.


5.Design load and application:Rolled lead screw assembly can be used in high,medium,light load in vertical and horizontal applications,automatic and manual adjustment of a variety of patented backlash nuts using thread or flange installation.Provide an effective cost solution.


6.Lubrication:lead screw can use a variety of wear-resistant,temperature resistant,self-lubricating,maintenance-free and long life composite engineering plastic nuts and screw with solid lubrication coating,correct lubrication must achieve satisfactory working life.Special grease for molybdenum disulfide lead screw(spray)is recommended for use in long fine rod assembly applications.The lead screw assembly needs to be lubricated frequently to keep a uniform layer of lubricant on the lead screw at all times.The lubrication interval is determined according to the actual application condition.Note:CJ composite engineering plastic nuts are self-lubricating and non - lubricating.For maximum life,it is recommended to use an initial coating lubricant.

 

7.Efficiency:Efficiency increases with the increase of the lead,except for particularly large leads.Although lead screws with self-lubricating composite engineering plastic nuts have very low friction coefficient and excellent lubrication performances.Ball screw transmission efficiency is higher than the lead screw.High efficiency and good cost performance of high speed lead screw can replace ball screw in a certain range.


ALM factory


ALM originally established in year of 2005.From a small factory,ALM nowadays has four production workshops for ball screw,lead screw,linear motor,linear actuator,linear guideways and related CNC machining parts for automation industry.Total areas over 7000 square meters,109 employees.Above 8 technical engineers are with over 20 years’ experience in linear motion filed.
