> Screw Rod

Through rolling friction to achieve motion conversion, compared to a sliding screw,  resulting in higher transmission efficiency. This component is widely used in various high-end equipment fields.

Cycloidal Planetary Roller Screw

Cycloidal Planetary Roller Screw

The recirculating planetary roller screw is a high-precision, high-rigidity precision planetary roller screw. With its unique structure and extremely small lead, it achieves ultra-high positioning capability, making it very suitable for applications requiring high accuracy and relatively moderate motion speeds. It is applicable to precision CNC grinding machines, high-performance simulation test benches, optical focusing systems, and similar products.

High-Load End-Cap Recirculating Ball Screw

High-Load End-Cap Recirculating Ball Screw

The high-load end-cap circulation ball screw can be seen as the “reinforced version” of the standard end-cap circulation series. While retaining the advantages of compact structure, low noise, and high precision, it significantly improves load capacity and rigidity through special circulation and contact angle designs, achieving a combination of high load, high speed, and high rigidity. It is suitable for CNC machining centers, large injection molding machines, heavy-duty automated production lines, and similar products.
