Các 7318-B-TVH is a specific type of angular contact ball bearing. Here’s a breakdown of its key features and typical applications:
Key Features:
- Kiểu: Angular Contact Ball Bearing
- Designed to handle combined radial and axial loads.
- The contact angle allows for higher axial load capacity compared to deep groove ball bearings.
- Kích thước:
- Các “7318” indicates the bearing size:
- 7: Series (angular contact bearing).
- 3: Medium duty.
- 18: Bore diameter of 90 Mm (calculated as 18 x 5 = 90 Mm).
- Các “7318” indicates the bearing size:
- Designation:
- B: Indicates a contact angle of 40°, which is suitable for higher axial loads.
- TVH: Refers to the cage material and design:
- T: Phenolic resin (thermosetting) cage.
- V: Filled with a specific type of lubrication.
- H: Indicates special internal design or tolerances.
- Material:
- Typically made from high-quality steel (e.g., chrome steel) for durability and performance.
- The cage is made of phenolic resin, which is lightweight and suitable for high-speed applications.
- Lubrication:
- The bearing is pre-lubricated with grease, as indicated by the “V” in the designation.
- Precision:
- Angular contact bearings are often manufactured to high precision standards, making them suitable for applications requiring accurate rotation.
Applications:
Angular contact bearings like the 7318-B-TVH are commonly used in applications where high axial and radial loads are present, such as:
- Machine tool spindles
- Pumps
- Hộp số
- Industrial motors
- Aerospace systems
- High-speed applications
Installation:
- Angular contact bearings are typically mounted in pairs (back-to-back or face-to-face) to handle axial loads in both directions.
- Proper preload and alignment are critical for optimal performance and longevity.
If you need further details, such as load ratings, exact dimensions, or specific technical data, consult the manufacturer’s datasheet or contact a bearing supplier.
