The 7319-B-TVH is a specific model of angular contact ball bearings. Here’s a breakdown of its key features and specifications:
1. Type of Bearing:
- Angular Contact Ball Bearing: Designed to handle combined radial and axial loads, with the load capacity depending on the contact angle. These bearings are typically used in pairs or sets to accommodate axial loads in both directions.
2. Dimensions:
- The 7319-B-TVH follows standard ISO dimensions for metric bearings.
- Inner Diameter (d): 95 Mm
- Outer Diameter (D): 200 Mm
- Amplada (B): 45 Mm
3. Design and Configuration:
- B: Indicates a 40° contact angle, which is optimized for higher axial load capacity.
- TVH: Refers to the cage material and design:
- T: Denotes a glass fiber-reinforced polyamide (plastic) cage.
- VH: Indicates a special heat stabilization process for the cage, making it suitable for high-temperature applications (up to 150°C or 300°F).
4. Load Capacity:
- Angular contact bearings are designed to handle both radial and axial loads simultaneously.
- The 7319-B-TVH has a high axial load capacity due to its 40° contact angle.
5. Applications:
- Commonly used in applications requiring high precision and rigidity, such as:
- Machine tool spindles
- Gearboxes
- Pumps
- Compressors
- High-speed applications
6. Lubrication:
- These bearings are typically lubricated with grease or oil, depending on the application requirements.
7. Mounting:
- Angular contact bearings are often mounted in pairs (back-to-back or face-to-face) or in sets of three or more to handle axial loads in both directions.
8. Manufacturer Variations:
- The 7319-B-TVH is produced by various bearing manufacturers (e.g., SKF, FAG, NSK, Timken). While the basic dimensions and design are standardized, there may be slight variations in materials, tolerances, or cage designs.
