The NACHI 5203 Angular Contact Ball Bearing is a high-performance component designed for demanding applications. It features a 17 mm inner diameter, a 40 mm outer diameter, and a width of 17.5 mm. This double-row bearing has a contact angle of 20 degrees, allowing it to handle both radial and axial loads effectively. It offers a dynamic load capacity of 15,000 N and a static load capacity of 9,250 N. The bearing is suitable for high-speed operations, with a maximum speed of 12,000 rpm under grease lubrication and 17,000 rpm under oil lubrication. Its robust design makes it ideal for use in blower systems, vacuum pumps, and other machinery requiring precise rotational movement.
