1306-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1306-K-TVH-C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate use. Its primary advantage lies in its ability to accommodate combined loads—significant radial loads with moderate axial loads in both directions—making it an ideal, compact solution for high-reliability machinery where space and performance are critical.
1306-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Basic bearing designation indicating a metric series double row angular contact ball bearing. |
| K | Signifies a tapered bore with a 1:12 ratio, enabling precise interference fit on adapter sleeves or withdrawal sleeves for secure mounting. |
| TVH | Denotes a glass fiber reinforced polyamide (Nylon) cage. This cage design contributes to lower friction, reduced weight, and is suitable for high-speed operation. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications with significant thermal gradients or where interference fits are used, preventing preload and potential seizure. |
1306-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior high rigidity, enabling the bearing to handle substantial combined loads effectively.
- High-Speed Capability: The lightweight and robust TVH nylon cage ensures stable operation and low centrifugal forces, supporting the bearing's high limiting speed of 13,000 rpm.
- Tapered Bore for Secure Mounting: The K-designation tapered bore allows for precise axial positioning and a secure, slip-free fit on the shaft when used with appropriate adapter sleeves.
- Optimized Internal Clearance: The C3 clearance group ensures reliable performance in applications prone to thermal expansion, preventing performance degradation due to excessive preload.
- Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, ensuring long service life and consistent performance under demanding conditions.
