Core Product Advantages

Superior Load Capacity: Expanded contact areas between rolling elements and raceways distribute loads more evenly, providing maximum support across radial, reverse radial, lateral, and moment loads.
High Structural Rigidity: Optimized carriage geometries and strict preload management minimize elastic deformation during heavy cutting, resulting in better cutting stability and operational consistency.
Smooth Recirculating Motion: The precision rolling contact mechanism ensures low friction, low driving resistance, and high-frequency movement capabilities compared to sliding guide systems.

Typical Applications

CNC Machine Tools: Vertical/horizontal machining centers, milling machines, grinding equipment, and heavy-duty cutting systems.
Machine Tool Builders: Custom machine design, specialized industrial machinery, and scalable production equipment integration.
Industrial Automation: Robotic transfer systems, automated assembly lines, and high-reliability material handling systems.

Structural Design Features

Precision Ground Raceway: Engineered for exact ball-to-surface contact, optimizing load distribution, running smoothness, and positioning stability.
Reinforced Carriage Design: Built to withstand multi-directional loading (vertical, horizontal, reverse, and moment loads) without compromising structural integrity.
Optimized Recirculating Ball System: Internal circulation channels enable continuous, high-frequency rolling movement with minimal frictional resistance.

Accuracy Grade and Preload Selection

Accuracy Grades
