1308-TVH Bearing Product Overview & Core Advantages
The 1308-TVH is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric bearing features an open design without integral seals, making it ideal for systems where external sealing is provided or where maximum speed is critical. Its double row construction enables it to accommodate significant combined loads—simultaneously handling radial forces and axial loads from both directions. Manufactured with chrome steel rings and balls, and a nylon cage, it offers excellent performance in high-speed operations, as indicated by its limiting speed of 9,500 rpm. The bearing comes pre-lubricated and is characterized by its compact dimensions (40 mm bore, 90 mm OD, 23 mm width), providing a robust solution for demanding industrial environments.
Model Code Breakdown
| Suffix | Technical Meaning |
|---|---|
| 1308 | Basic bearing designation indicating metric dimensions: 40mm bore, 90mm OD. |
| TVH | Signifies a nylon cage (polyamide cage) and a CN radial internal clearance. The "V" may indicate special design features for vibration control or optimized internal geometry. |
1308-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior rigidity compared to single row bearings, enabling stable operation under heavy combined loads (radial and bidirectional axial loads). With a dynamic load rating of 7605 lbf and static load rating of 2520 lbf, it delivers reliable performance in strenuous applications.
- Optimized High-Speed Performance: The lightweight nylon cage (TVH) reduces centrifugal forces, minimizes friction, and contributes to the high limiting speed of 9,500 rpm. This makes it suitable for high-speed applications.
- Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.012mm to 0, OD: -0.015mm to 0), ensuring precise fit and smooth operation. The standard CN radial internal clearance is suitable for most operating conditions.
- Pre-Lubricated & Ready-to-Use: The bearing is supplied with initial lubrication, facilitating easy installation and immediate operation within a temperature range of -30°C to 110°C.
1308-TVH Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for supporting shafts in medium-duty motors requiring high-speed capability and rigidity.
- Industrial Gearboxes: Used in gearbox assemblies where combined loads are present and space is constrained.
- Material Handling Equipment: Suitable for conveyor pulleys, rollers, and other components demanding robust bearing performance.
- Agricultural Machinery: Applied in tractor transmissions and implement drives where reliability under varying loads is essential.
- General Industrial Machinery: A versatile choice for pumps, fans, and other machinery requiring a durable, double row ball bearing.
