1304-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1304-K-TVH-C3 is a metric double row angular contact ball bearing engineered for applications demanding high precision and robust performance. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing is designed to accommodate significant radial loads. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. The combination of a nylon cage and high-quality chrome steel construction ensures smooth operation, high rigidity, and reliable performance in demanding industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1304 | Basic bearing designation indicating bore diameter (20 mm) and series |
| K | Tapered bore with a 1:12 ratio for precise mounting on tapered shafts |
| TVH | Nylon cage (polyamide) design for reduced friction and quiet operation |
| C3 | Greater than normal radial internal clearance for thermal expansion compensation |
1304-K-TVH-C3 Bearing Structural Features & Performance Benefits
Double Row Design for Enhanced Rigidity: The double row ball bearing construction provides superior stiffness and load capacity compared to single row bearings, making it ideal for applications requiring high radial load support and minimal deflection.
Optimized Load Capacity: With a dynamic load rating of 3218 lbf and static load rating of 900 lbf, this bearing delivers reliable performance under substantial radial forces. The angular contact design enables effective load distribution across both rows of balls.
High-Speed Capability: The nylon cage (TVH) contributes to reduced friction and lower operating temperatures, supporting a limiting speed of 18,000 rpm. This makes the bearing suitable for high-speed applications while maintaining smooth operation.
Precision Tapered Bore: The 1:12 tapered bore (K designation) ensures precise mounting on tapered shafts, providing secure fixation and eliminating clearance between the bearing and shaft for optimal power transmission.
Controlled Internal Clearance: The C3 clearance provides greater than normal internal space, accommodating thermal expansion in applications with elevated operating temperatures or interference fits.
