Specification

Advantages

Load Capacity & Service Life
The HGKH series features an advanced four-direction equal load design with optimized raceway geometry, providing approximately 20-30% higher load capacity than standard models. The raceways are manufactured from high-grade steel hardened to HRC 58+, ensuring excellent wear resistance and impact load capability. The precision ball recirculation system with larger diameter balls distributes stress effectively, while enhanced multi-layer sealing protects against contaminants, guaranteeing extended service life in demanding industrial environments.

Precision Performance & Accuracy
Utilizing precision grinding technology and rigorous quality control, the HGKH maintains exceptional running parallelism within tight tolerances. The adjustable preload mechanism allows precise clearance control, enabling selection from multiple preload levels to match specific application requirements. This engineering approach ensures micron-level positioning accuracy and excellent repeatability for precision machining and measurement applications.

High-Speed Capability & Stability

The optimized ball recirculation system with special retainer design enables smooth operation at speeds up to 5 m/s. The reinforced structure maintains outstanding stability during rapid acceleration and deceleration cycles. Even under frequent start-stop conditions and directional changes, the HGKH consistently delivers reliable performance, making it ideal for high-speed automation applications.

Application
Widely used in CNC machining centers, precision grinding machines, industrial robotics, semiconductor equipment, and automated welding systems. The series is particularly suitable for applications requiring high precision, heavy-load capacity, and reliable performance in demanding conditions.
