• Superior Material: Constructed from high-carbon chromium bearing steel, professionally heat-treated to achieve the required hardness, and equipped with a precision cage to reduce friction loss, extend bearing life, and adapt to various working conditions.
• Manufacturing: Strictly adhering to ISO precision standards, the raceways are smooth and burr-free, ensuring high rotational accuracy. Pre-tensioning can enhance rigidity, preventing vibration during high-speed operation, making it suitable for machine tool spindles, precision motors, and other equipment.
• The unique angular contact geometry allows it to withstand both radial and single-direction axial loads simultaneously, making it ideal for applications requiring high rigidity and precise axial positioning, such as machine tool spindles, motors, and transmission systems.
• Precision-ground on advanced grinding machines, it ensures ultra-high roundness and surface finish of raceways and balls. Combined with high-quality grease, it achieves extremely low operating noise and vibration, providing a quiet and smooth working experience for your equipment.
• Wide Application: Compatible with machine tools, high-speed motors, precision instruments, air compressors, and other equipment, balancing rigidity and high-speed performance, offering excellent cost-effectiveness, and meeting the core needs of industrial transmission.
