1304TN Bearing Product Overview & Core Advantages
The 1304TN is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design without seals, optimized for high-speed operation with a limiting speed of 18,000 rpm. Its double row construction provides superior rigidity and enables it to handle significant combined loads (radial and axial) simultaneously. The precision-ground chrome steel components and nylon cage contribute to smooth operation and extended service life in demanding environments.
