1305KTN Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle combined loads effectively. With a dynamic load rating of 4275 lbf and static load rating of 1215 lbf, it offers reliable performance under demanding conditions.
Precision Performance: Manufactured with CN radial internal clearance and tight dimensional tolerances, this bearing ensures smooth operation and precise positioning in high-precision applications.
Optimized Speed Capability: The lightweight nylon cage (TN) reduces centrifugal forces, contributing to a limiting speed of 15,000 rpm. This makes it suitable for high-speed applications requiring stable rotation.
Easy Mounting & Maintenance: The tapered bore (K) facilitates precise mounting and adjustment on tapered shafts, while the open design allows for customized lubrication strategies based on application requirements.
