Le 7205B Angular Contact Ball Bearing is a high-speed precision bearing designed with a 40° contact angle, allowing it to support higher axial loads compared to standard angular contact bearings. It is ideal for applications requiring both high rotational speed and strong axial load capacity.
Manufactured from premium chrome steel, and available in stainless steel and ceramic options, the 7205B bearing offers excellent rigidity, low friction, and reliable performance under demanding conditions. Its optimized internal geometry ensures smooth operation, reduced heat generation, and extended service life.
The 7205B bearing is commonly used in paired or duplex configurations to support axial loads in both directions, making it suitable for high-speed spindles, precision machinery, and industrial equipment.
