The 7308BMU Nachi angular contact ball bearing is engineered for high-performance applications requiring combined radial and axial loads, featuring a 40 mm inner diameter, 90 mm outer diameter, and 23 mm width for precise fitment in demanding environments. With a dynamic load rating of 46,000 N and a static load rating of 31,000 N, this bearing delivers robust durability and reliability. It utilizes a brass cage for enhanced strength and smooth operation, offers a 40° contact angle for optimal axial load capacity, and comes with C3 radial clearance for flexibility in mounting. The maximum grease speed is 6,300 rpm, making it suitable for high-speed machinery, while its all-steel construction ensures long service life and consistent performance under heavy loads.
