20mm Left-Hand Ball Lead Screw 2003 Series 700mm | CNC Machinery & Automation

Product Details:

 Engineered for Precision and Reliability in Demanding Applications

The 2003 series left-hand ball lead screw is designed for applications where standard right-hand threads risk loosening under counterclockwise rotation—such as CNC spindles, vertical axes, and conveyor systems. Its 700mm travel length supports extended-range motion without compromising rigidity or accuracy.

Key Features:

Left-Hand Thread Design: Prevents unintended loosening in reverse-rotation environments.

Integrated Ball Nut: Pre-lubricated and preloaded for immediate installation and zero initial backlash.High Load Capacity: Supports axial loads up to 8,500N (depending on support configuration).

Low Friction & High Efficiency: >90% mechanical efficiency reduces motor strain and energy consumption.

Customizable Options:

• Length: Standard 700mm; custom from 100mm to 2,000mm

• Material: Carbon steel (45#), chrome steel, or stainless steel (304/316)

• Surface Treatment: Black oxide, zinc plating, or hard chrome for corrosion resistance

• Accuracy Grade: C7 (standard) or C5 (high-precision)

• Fast Turnaround: Samples in 3–5 days; bulk orders in 7–10 days.

Technical Specifications:

• Diameter: 20mm

• Lead: 3mm (standard for 2003 series)

• Length: 700mm (customizable)

• Thread Direction: Left-hand (LH)

• Material: 45# carbon steel (hardened raceways, HRC 58–62)

• Ball Nut Type: Single nut (standard); double nut available on request

• Operating Temperature: –20°C to +120°C

• Backlash: <0.02mm (with preload option)

Typical Applications:

• CNC milling machines and routers (Z-axis or specialized axes)

• 3D printers with dual-extruder systems

• Robotic arms requiring secure anti-loosening threads

• Packaging and labeling automation

• Semiconductor handling equipment

• Medical imaging devices
