Benefits of Lead Screw for Our Customers
- Solve Customers' Problems. it will greatly enhance the customer's professionalism, reputation, and brand while solving customers’ design problems or others.
- Because the lead screw has a self-locking effect, which prevents the machine from reversing due to load changes.
- Because it has large torque and high efficiency due to friction between the screw thread and the screw nut.
- Because the high precision of the lead screw can meet the needs of some precision driving.
- Importantly, we are a professional manufacture and solution provider, pretty many customers always refer their customers to contact us for purchase. Johoty is surely worthy of your trust!

Features of Lead Screw
- Lead screw is made of a screw and nuts, its function is to mainly transfer rotary motion to straight linear motion.
- Its working environment is high temperature, certain corrosion, strong wear, and high torque. So, lead screw will not deform under high temperature, high life cycle with high wear resistance. Its raw materials have strong corrosion resistance.
- High strength, capable of withstanding high torque and high rotational speed. Small residual stress, and small thermal deformation after heat treatment.
ACME Screw
- It is a special trapezoidal screw for industry application, it has screw thread profile of trapezoidal screw, but its angle is 29° witch providing high efficiency and stiffness,
- ACME screws have high loading capacity and are ideal for heavy-duty applications. they commonly used in CNC machine tools, lathes, and milling machines.
Ball Screw
- Compared to ACME screw, ball screw is to smoothly move by adding steel balls between the screw and nut, it can greatly reduce friction loss and keep high efficiency (90%) and precision.
- It can reduce the requirements of motor driving and save costs. And, 90% of ball screws can archive their design life cycles, and 50% of ball screws have long life cycle exceeding the design life cycle by 2~4 times.
- Ball screw has a very low starting torque force, it has very low noise during operation, no leakage, no filtration required, energy saving, and high reproducibility.
- Ball screw is very suitable for high-speed, is typically used in the aerospace, automotive, medical industry, electronic machinery including measuring instruments, X-Y platforms, factory automation equipment, PCB drilling machines, IC packaging machines, semiconductor equipment, factory automation equipment, etc.
- Industry including aircraft flaps, airport load equipment, tail brake, brakes used for antennas, valve switching devices, solar panel telescoping mechanisms, electron microscope focusing mechanisms, etc
Square lead screw
- The thread profile can achieve a close fit between the screw and nut, achieving highly efficient motion transmission. Its sturdy structure makes it resistant to wear and tear, making it a reliable choice for high-load and frequently used applications.
- With our precision machining and our professional design, square lead screw is crucial for manufacturing processes that require precise positioning and movement
Trapezoidal Screw
- Its precision tolerance is very small because its shaft has high precision and high wear resistance. tensile strength is 275~314N/mm2, tensile endurance (0.2%) is 216~245N/mm2.
- Compressive strength is 539~686N/mm2, compression endurance (0.2%) is 294~343N/mm2, fatigue strength is 294~343N/mm2 , charpy impact value is 132N/mm2X102 , Its angle is 30° for screw thread, but ACME screw is 29°，
- The small angle differences provide higher carrying capacity and efficiency, Trapezoidal screw is typically used in industrial applications, such as linear actuators, sliding doors and conveyor systems.
