Product Display
Ultra-high load capacity and high rigidity
The rolling elements and screw raceways adopt a line contact design. Compared with the point contact of ball screws, the contact area is significantly increased, and the load is distributed more evenly. This makes its load-bearing capacity far exceed that of products of the same specification, which can be easily adapted to high-load scenarios such as servo presses and heavy-duty electric cylinders. At the same time, it has excellent structural rigidity with minimal deformation under stress, effectively ensuring the accuracy of transmission and positioning.
High speed and high acceleration
The structural design without a return circulation device eliminates the restrictions of traditional circulation structures on the movement of rolling elements. The rolling elements run continuously and stably along the raceways, with greatly reduced frictional resistance and energy loss, enabling higher moving speed and rapid acceleration/deceleration response, which perfectly matches scenarios with high dynamic performance requirements such as humanoid robot joints and automated production lines.
High precision retention
The key transmission components reach a hardness of over HRC58 after quenching, with extremely strong surface wear resistance. It can effectively resist long-term frictional loss, reduce precision attenuation, and improve adaptability to harsh working conditions. Even in high-frequency work cycles, it can stably maintain the initial precision and extend the precision stability cycle of equipment.
