The Nachi 7216BMU angular contact ball bearing features a 40° contact angle and a machined brass cage, designed for high precision and durability. It has an inner diameter of 80mm, an outer diameter of 140mm, and a width of 26mm, with flush ground surfaces for smooth operation. This single-row bearing supports dynamic loads up to 77,100 N and static loads up to 65,000 N, with maximum speeds of 4,000 rpm using grease lubrication and 5,400 rpm with oil. Its C3 clearance allows for thermal expansion, making it suitable for high-speed, high-load applications requiring reliability and low noise. Manufactured in Japan, it is ideal for pump and machine tool applications.
