Product Grade

1. High precision transmission

Positioning accuracy: Through precision grinding technology and optimized cyclic structure, the repeated positioning accuracy can reach ± 0.01mm, meeting the micro level control requirements of CNC machine tools, semiconductor equipment, and other devices.

Stability: Pre pressing is used to eliminate gaps (double nuts or spring pre pressing), ensuring no backlash error during continuous movement.

2. Efficient transmission

Low friction loss: The rolling friction design achieves a transmission efficiency of over 90% and reduces energy consumption by 60% compared to traditional sliding screws.

Quick response: With minimal friction resistance, it supports high-speed operation and is suitable for high-speed positioning scenarios in automated production lines.

3. Long lifespan and reliability

Wear resistant material: using alloy steel for quenching, grinding or surface hardening treatment, with strong fatigue resistance and a service life of 5-10 times that of ordinary screw rods.

Sealed protection: The dust collector and waterproof design effectively resist the erosion of dust and moisture, and are suitable for harsh working conditions such as automobiles and injection molding machines.

4. High rigidity load capacity

Structural strengthening: Through pre pressing and reversing optimization, the axial stiffness is increased, which can withstand heavy load impacts (static loads up to hundreds of kilonewtons).

Customized adaptation: Supports variable designs such as heavy-duty and high-speed models to meet differentiated load requirements in industrial robots, aerospace, and other fields.

5. Mute and environmental adaptability

Low noise operation: Special groove design and precision ball guide reduce vibration noise, suitable for sensitive scenarios such as medical equipment and laboratory instruments.

Lubrication optimization: Self lubricating or maintenance free design reduces manual intervention, suitable for clean rooms, food processing and other oil-free environments.

6 Dustproof and corrosion-resistant

Customized dust-proof and corrosion-resistant coating for ball screws, capable of maintaining stable operation in harsh working environments

Nominal diameter (outer diameter):

The outer diameter of the screw directly affects its load-bearing capacity, with larger diameters resulting in higher loads.

Lead (pitch):

The distance that the nut moves in a straight line per revolution of the screw.

Effective itinerary and total length:

Total length=effective travel+nut length+design allowance+support end length+coupling connection length;

Thread length ≥ effective travel+nut length+collision allowance

Load capacity:

Dynamic rated load (Ca): the maximum axial load in motion;

Static rated load (C0a): the maximum load in a static state;

Selection rule: Actual load/Ca ≤ 0.7 to extend lifespan.

Accuracy level: C3, C5, C7
