The 7310BMU Nachi angular contact ball bearing features a 50mm bore, 110mm outer diameter, and 27mm width, designed with a 40° contact angle for high axial and radial load capacity. It has a brass cage and is flush ground for precision fit, with an open design and ABEC 1 (ISO P0) tolerance. The bearing supports a dynamic load rating of approximately 68,000 to 70,500 N and a static load rating near 49,500 N, with a maximum speed around 5,500 rpm. This single-row bearing is ideal for applications requiring high rigidity and accuracy, made in Japan for quality assurance.
