The NACHI NU307EG is a high-capacity, single-row cylindrical roller bearing designed for demanding electrical and industrial applications, featuring a 35 mm inner diameter, 80 mm outer diameter, and 21 mm width for precise fit and robust performance. Engineered in Japan, this bearing offers a dynamic load rating of 66,500 N and a static load rating of 65,500 N, ensuring reliable operation under heavy radial loads. Its advanced glass-reinforced nylon (PA66) cage reduces noise and heat generation, while the open design allows for easy maintenance and lubrication. The NU307EG’s large rollers and optimized internal geometry maximize load capacity and service life, making it an ideal choice for high-speed, high-load environments where durability and efficiency are critical.
