THSL-8D 8mm Lead Screw

THSL-8D 8mm Lead Screw

Specifications:

1. Material:

• Screw Material: Stainless steel, carbon steel, or other durable materials (typically with anti-corrosion coatings).
• Nut Material: Usually brass or POM (Polyoxymethylene) for low-friction, wear-resistant performance.

2. Dimensions:

• Screw Diameter (Outer Diameter): 8 mm
• Pitch: 2 mm (the distance between threads)
• Lead: 8 mm (distance the nut moves per revolution of the screw)
• Thread Type: 4-start (the screw has 4 independent thread paths, which is why the lead is 8 mm even though the pitch is 2 mm)
• Length: Varies (typically available in lengths such as 100 mm, 200 mm, 300 mm, 500 mm, or custom sizes)

3. Lead (Travel per Revolution):

• Lead: 8 mm (This means that for each full rotation of the lead screw, the nut moves 8 mm along the axis.)

4. Performance:

• Efficiency: Typically high for lead screws of this type, especially when paired with an appropriate anti-backlash nut.
• Anti-backlash: Can be used with an anti-backlash nut to minimize backlash, enhancing precision.
• Linear Motion: Provides smooth and precise linear motion.
• Max Speed: Depends on the application, but generally suited for speeds of up to 500 RPM or more in light-duty applications.
• Axial Load: Can typically handle light to moderate loads (depends on material and nut used).

5. Nut Type:

• Available with a variety of nut types, including:
  • Brass Nut: Offers good durability and is typically used in industrial applications.
  • POM Nut (Delrin Nut): Provides smoother operation with lower friction, ideal for applications like 3D printers where frequent movement is required.

6. Applications:

• 3D printers
• CNC machines
• Linear actuators
• Automation equipment
• Precision positioning systems

Key Benefits of THSL-8D 8mm Lead Screw:

• Precision Movement: The 8mm lead provides a balance between speed and precision.
• Self-locking: Lead screws can have self-locking properties depending on the angle of the threads, which can be advantageous in vertical applications.
• Durable: Stainless or carbon steel construction ensures good wear resistance.
