8483900090
Tr3.5x1.22 lead screw is suitable for small and space limited application.T3.5 trapezoidal lead screw pitch is 1.22mm.3.5x1.22 lead screw with POM nut has the characteristics of corrosion resistance,wear resistance and self-lubricated.
| Product name | Pitch 1.22mm T3.5 Miniature Tr3.5x1.22 Trapezoidal Lead Screw |
| Lead screw model | Diameter 3.5mm,Lead 1.22mm,Pitch 1.22mm |
| Lead screw material | ASTM1045,SUS303,SUS304,SS316,SS316L (other customized materials,according to customer requirements) |
| Lead nut material | Brass,Tin bronze,Phosphor bronze,Aluminum bronze,POM,PEK,nylon,POK,Stainless steel,1045,Zinc alloy,Brass+Plastic,Aluminum alloy+Plastic,Brass+Steel,Self lubricating(No oil type) |
| Lead screw quality standard | ISO2901-4,DIN103 |

For more information,pls contact the salesman.
| Lead Screw Thread Types |
1.T ISO Trapezoidal Thread Din103
For transmission and position adjustment,widely used in the mechanical industry.
2.H High-helix Screws
A high-helix lead screw,speedy multi-start lead screw,or steep lead screw features a high pitch that is used to transform a smaller radial movement into a large axial movement.
3.M ISO Metric Thread (60°)
The most common form of thread used for fastening and precision transmission.
4.A ACME Thread (29°)
Inch threads can also be used for fastening connections,but not for high accuracy.
5.R Knuckle Thread
With the same arc thread as ball screw,the transmission is smoother.
6.G Gothic thread
Gothic double arc thread,offering the advantages of ball screw,is similar a new kind of lead screw.
7.X Self-reversing thread
A screw that makes the slide block reciprocate without changing the rotation direction of the spindle.

| Lead Screw Application |
Lead screws are commonly used in instrument-level applications that require smooth,precise,clean,and maintenance-free operation.The common application industry of the lead screw are shown in the figure below.
| 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.
Other ready lead screw models are available
