The NACHI 5213 angular contact ball bearing is designed for high-performance applications, featuring a 65 mm inner diameter, 120 mm outer diameter, and a width of 38.1 mm. It is a double-row open bearing with a dynamic load capacity of 89,000 N and a static load capacity of 77,000 N. The bearing operates at a contact angle of 20 degrees, making it suitable for applications requiring both radial and axial load support. It is commonly used in machinery such as blowers, vacuum pumps, and transmissions, where high rotational speeds and reliability are crucial. The bearing's open design allows for easy maintenance and inspection.
