Diameter 12mm Lead 2.5mm Tr12x2.5 Trapezoidal Lead Screw.The pitch of the lead screw is 2.5mm.The lead screw can operate in very challenging environments,including some conditions that the ball screw cannot withstand.One reason for this is that lead screws have no circulating elements,which are highly susceptible to debris and contamination.But another reason is that lead screw nuts can be made of a variety of materials,including bronze and various plastics,to adapt to environmental conditions.Lead screw shafts can be made of carbon steel,stainless steel or aluminum,and they usually come with a surface coating to provide additional protection against contamination.

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.
Other ready models are available
What's the difference between lead screw designs?
In power transmission applications,there are two main types of screw drives:screw drives that use a recirculating ball or roller for applications requiring high rigidity,excellent positioning accuracy,and high duty cycle ratio,and screw drives that rely on sliding contact for applications requiring corrosion resistance,self-locking operation,and customizable nut designs.
The second type - screw drivers with sliding contact between the nut and the screw shaft - is called lead screw,Acme screw or trapezoidal screw.Although these names are often used interchangeably,they actually refer to different screw geometrics and sizes.Here is a breakdown of the different types of sliding contact screws and what the terms "lead screw," "Acme screw," and "trapezoidal screw" really mean.
Lead Screws
The most commonly used of the three terms "lead screw" refers only to a powered screw that relies on the sliding motion between the nut and the screw shaft.There are two variations of the lead screw:the screw with square thread and trapezoidal thread.
Lead screw designs for power transmission use almost exclusively trapezoidal threads,which are easier to manufacture and have higher load capacity than screws with square threads.However,trapezoidal threads do have higher friction and are therefore less efficient than the square thread form.
A power screw is a screw that transmits power by converting rotating motion into linear motion.The lead screw and ball screw are the types of power screws.
ACME Screws
As mentioned above,the lead screw for power transmission uses the trapezoidal thread form.But the trapezoidal screw design can be threaded at 29° or 30° angles,which means that the trapezoidal screw comes in two versions.
The first version(called the Acme screw)has a thread angle of 29° and is manufactured in inch size.Acme screw size is usually specified by the screw shaft diameter and the number of threads per inch or TPI.
Trapezoidal Screws
Trapezoidal screws also use the trapezoidal screw form of lead screw,but the trapezoidal screw thread angle is 30° and manufactured in metric size.The size of the trapezoidal screw is specified by the shaft diameter of the screw and the pitch of the screw thread.Trapezoidal screws are sometimes called "metric screw" or "metric Acme screw".
ALM originally established in year of 2005.From a small factory,ALM nowadays own factory 7000 square meters,109 employees.Above 8 technical engineers are with over 20 years' experience in linear motion filed.
