1308-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1308-K-TVH-C3 is a double row angular contact ball bearing engineered for applications requiring exceptional rigidity and the capacity to handle combined loads. Featuring a Metric tapered bore (1:12), this precision bearing is designed to accommodate significant radial loads while managing axial loads in both directions. Its compact design, with optimized bearing dimensions (40mm bore, 90mm OD, 23mm width), makes it ideal for high-reliability machinery where space constraints and performance are critical. The C3 radial internal clearance ensures optimal operation under varying thermal conditions.
1308-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Basic bearing series designation, indicating the core dimensions (40mm bore, 90mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting on adapter sleeves or withdrawal sleeves. |
| TVH | Indicates a Nylon (Polyamide) cage. This cage design contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
| C3 | Specifies a greater than normal radial internal clearance. This is essential for applications with significant thermal expansion or where interference fits are used, preventing preload and ensuring smooth operation. |
1308-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial combined loads (radial and bidirectional axial loads) simultaneously, as evidenced by its dynamic load rating of 7605 lbf.
- Optimized for High-Speed Operation: The lightweight Nylon cage (TVH) reduces centrifugal forces, allowing for a high limiting speed of 9,500 rpm, making it an excellent high-speed bearing.
- Tapered Bore for Secure Mounting: The K designation for the tapered bore ensures a tight, slip-free fit on a shaft when used with an adapter sleeve, enhancing operational stability.
- Pre-Lubricated for Immediate Service: The bearing comes lubricated from the factory, ready for installation and initial operation, reducing setup time.
- Durable Material Construction: Manufactured from Chrome Steel for both rings and balls, ensuring high durability and resistance to wear under demanding conditions.
1308-K-TVH-C3 Bearing Typical Application Areas
