1305-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1305-K-TVH-C3 is a double row angular contact ball bearing engineered for applications requiring high precision and exceptional rigidity. Featuring a tapered bore design (1:12), this bearing excels at handling combined radial and axial loads simultaneously. Its double row construction provides superior high rigidity and load-carrying capacity in a compact envelope. Pre-lubricated and featuring a nylon cage, it delivers reliable performance and is ideal for demanding industrial environments where precision and durability are paramount.
1305-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1305 | Standard bore diameter (25 mm) and dimension series |
| K | Tapered bore with a 1:12 ratio |
| TVH | Nylon (polyamide) cage, snap-type design |
| C3 | Greater than normal radial internal clearance |
1305-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides significantly increased rigidity and enables the bearing to support substantial combined loads (both radial and axial) from both directions.
- Tapered Bore for Secure Mounting: The K-suffix tapered bore allows for precise interference fit on a tapered shaft adapter or withdrawal sleeve, ensuring a secure and concentric mounting, which is critical for high-speed and high-precision applications.
- Optimized High-Speed Performance: The lightweight nylon cage (TVH) reduces centrifugal forces, lowers friction, and contributes to a high limiting speed of 15,000 rpm, making it a capable high-speed bearing.
- Pre-Lubricated for Immediate Service: The bearing comes pre-lubricated, facilitating easy installation and immediate operation without the need for initial greasing.
- Controlled Internal Clearance: The C3 clearance is larger than normal, making it suitable for applications with expected thermal expansion or where heavy interference fits are used.
1305-K-TVH-C3 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and precision equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Systems
- Agricultural Machinery
- Various machinery requiring a robust bearing solution for combined loads on a tapered shaft.
