1304J Bearing Product Overview & Core Advantages
The 1304J metric double row angular contact ball bearing is engineered for applications requiring high radial load capacity and precision performance. Featuring an open design with CN radial internal clearance, this bearing delivers exceptional rotational accuracy and stability. Its double row construction provides superior rigidity compared to single row alternatives, making it ideal for machinery demanding high precision and reliability. The bearing comes pre-lubricated for immediate installation and optimal performance across a wide temperature range from -30° to 110°C.
