The Nachi 7215BMU angular contact ball bearing features a 75mm inner diameter, 130mm outer diameter, and 25mm width with a 40° contact angle, designed for high axial and radial load capacity. It includes a machined high-strength brass cage and is flush ground for precision fit. The bearing has a dynamic load rating around 71,700 N and a static load rating near 60,000 N, with a C3 internal clearance for optimal performance. It supports speeds up to 4,300 rpm with grease lubrication and 5,800 rpm with oil, operating reliably up to 120°C. This single-row bearing is ideal for high-speed, high-load applications requiring durability and precision.
