Lead Screw
A lead screw, also known as a tension screw or threaded spindle, is a mechanical component used in various machines and devices. It serves to precisely control motion and transmit forces. Lead screws are used in mechanical engineering, the automotive and furniture industries, and many other fields where accurate linear motion is required.
Types of Lead Screws
- Trapezoidal Thread Screws: These screws have a trapezoidal thread profile and are robust and durable. They are commonly used in applications requiring high force transmission.
- Ball Screws: Featuring a rounded thread profile, these screws offer high efficiency and precision. They are ideal for precise motion control and are often used in CNC machines.
- Fine Thread Screws: With a fine thread profile, these screws are suitable for applications requiring high precision with low force transmission.
- Specialty Screws: Designed for specific applications, these screws may have various thread profiles and materials.
Features and Functions
- Precision: Enables accurate linear motion, essential in precision mechanics and machine construction.
