1305KJ Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row ball bearing configuration provides exceptional stiffness, making it suitable for applications requiring minimal deflection under load. The optimized internal geometry ensures stable operation even under demanding conditions.
Superior Load Capacity: Engineered to handle substantial radial loads with a dynamic rating of 4275 lbf and static rating of 1215 lbf. The bearing's construction allows for reliable performance in various loading scenarios.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and CN radial internal clearance for precise positioning applications. The tapered bore facilitates accurate mounting and adjustment on tapered shafts.
Material Excellence: Constructed from chrome steel for both rings and balls, ensuring high wear resistance and long service life. The steel cage provides robust support and maintains ball alignment under high-speed operation.
