1205-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1205-K-TVH-C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision performance. This metric bearing features a tapered bore (1:12 ratio) that enables precise interference fits for enhanced system stability. Engineered to handle significant combined loads including radial forces and bidirectional axial loads simultaneously, this bearing delivers exceptional performance in demanding industrial environments. With its optimized internal geometry and C3 radial internal clearance, it accommodates thermal expansion while maintaining operational precision.

1205-K-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under heavy combined loads.
Optimized Load Capacity: With a radial dynamic load rating of 3218 lbf and static load rating of 900 lbf, this bearing handles substantial radial and bidirectional axial loads simultaneously, ensuring reliable performance in demanding conditions.
Precision Engineering: The tapered bore (K-designation) allows for precise mounting on adapter sleeves or tapered shafts, ensuring optimal fit and reducing vibration. The nylon cage (TVH) provides excellent guidance for the balls while reducing weight and friction.
Thermal Management: The C3 radial clearance accommodates differential thermal expansion between bearing components and housing, preventing preload issues in applications with temperature variations up to 110°C.
High-Speed Capability: The combination of nylon cage and optimized internal geometry supports operation at limiting speeds of 18,000 rpm, making it suitable for high-speed applications.
