The NACHI 5312 is a double-row angular contact ball bearing designed for demanding electrical and industrial applications, featuring a 60 mm bore, 130 mm outer diameter, and 54 mm width for robust performance in compact spaces. With a dynamic load capacity of 128,000 N and a static load rating of 101,000 N, this bearing handles high radial and axial loads efficiently. It operates smoothly at speeds up to 3,800 rpm with grease lubrication and 5,000 rpm with oil, thanks to its precision-engineered JIS SUJ2 steel construction. The open design, 20-degree contact angle, and ISO P0 precision ensure reliable operation, making it ideal for machinery requiring durability, high load capacity, and long service life.
