Ar 7006 ACD is a specific type of Angular Contact Ball Bearing. Here’s a breakdown of its key characteristics:
1. Bearing Type: Angular Contact Ball Bearing
- Angular contact ball bearings are designed to handle combined radial and axial (thrust) loads. They have raceways in the inner and outer rings that are displaced relative to each other, allowing them to support axial loads in one direction.
2. Size and Dimensions:
- Ar 7006 refers to the bearing’s size designation.
- Typical dimensions for a 7006 bearing are:
- Inner Diameter (d): 30 milímetro
- Outer Diameter (D): 55 milímetro
- Ancho (B): 13 milímetro
3. Contact Angle:
- Ar ACD suffix indicates a 25-degree contact angle. This angle determines the bearing’s ability to handle axial loads. A 25-degree contact angle is common for applications requiring moderate axial load capacity and high-speed performance.
4. Design and Configuration:
- Ar 7006 ACD is typically a single-row bearing, meaning it has one row of balls.
- It is often used in pairs or sets (duplex arrangements) to handle axial loads in both directions or to increase rigidity.
5. Applications:
- Angular contact ball bearings like the 7006 ACD are commonly used in:
- Machine tool spindles
- Pumps
- Gearboxes
- High-speed applications
- Automotive components (e.g., wheel hubs)
6. Material and Lubrication:
- These bearings are usually made from high-quality steel (e.g., chrome steel) for durability and performance.
- They may come pre-lubricated with grease or require external lubrication depending on the application.
7. Precision and Clearance:
- Ar 7006 ACD may be available in different precision classes (e.g., ABEC-1, ABEC-3, etc.) depending on the manufacturer.
- Internal clearance can also vary based on the application requirements.
