1210-K-TVH Bearing Product Overview & Core Advantages
The 1210-K-TVH is a double row angular contact ball bearing engineered for applications requiring high rigidity and precision. Featuring a tapered bore (1:12) and open construction, this metric bearing is designed to accommodate combined loads—simultaneously handling significant radial forces. Its double row ball design provides enhanced stiffness and load-carrying capacity compared to single row alternatives, making it ideal for high-reliability machinery where precise shaft positioning and stability are critical. The bearing comes pre-lubricated and is optimized for efficient operation within a broad temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bore diameter (50 mm) and series designation |
| K | Tapered bore with a 1:12 ratio |
| TVH | Nylon (polyamide) cage, glass fiber reinforced |
1210-K-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing configuration provides superior radial stiffness and enables the bearing to support substantial combined loads. With a dynamic load rating of 5962 lbf and static load rating of 2059 lbf, it ensures reliable performance under demanding conditions.
- Precision Tapered Bore: The K-designation tapered bore (1:12) allows for precise axial positioning and secure mounting on tapered shaft seats, minimizing inner ring creep and enhancing system stability.
- Optimized High-Speed Performance: The lightweight nylon cage (TVH) reduces centrifugal forces, lowers friction, and contributes to a high limiting speed of 10,000 rpm. Pre-lubrication ensures smooth operation from startup.
- Wide Operating Temperature Range: Manufactured from chrome steel and compatible with standard lubricants, the bearing operates effectively from -30°C to 110°C.
- Standard Internal Clearance: The CN radial internal clearance is suited for most industrial applications, providing an optimal balance between fit, temperature management, and load conditions.
