7006 ACB/HCP4A Bearing Product Overview & Core Advantages
The 7006 ACB/HCP4A is a single-row angular contact ball bearing engineered for applications demanding high precision and high-speed operation. Designed to accommodate primarily axial loads in one direction, combined with radial loads, it features a 25° contact angle for optimal load distribution. Its construction with ceramic balls and P4 (ABEC-7) tolerance class ensures exceptional rotational accuracy, low heat generation, and extended service life in demanding environments.
7006 ACB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 13mm width). |
| AC | Angular Contact design, optimized for combined loads. |
| B | A 40° contact angle variant. (Note: The provided spec indicates a 25° angle. The 'B' suffix in this context may refer to a specific internal design or preload class. Please consult factory documentation for precise interpretation). |
| HC | Hybrid Ceramic, indicating the use of ceramic balls for reduced weight, lower friction, and higher speed capability. |
| P4 | Specifies the P4 tolerance class (ABEC-7), denoting very high precision levels for running accuracy. |
| A | Indicates that the bearing is supplied with a specific preload for enhanced rigidity. |
7006 ACB/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and allows for a limiting speed of 60,000 rpm. This makes it an ideal high-speed bearing.
High Rigidity & Load Capacity: The angular contact design and available preload provide high axial and radial stiffness, enabling the bearing to handle significant combined loads with minimal deflection.
Precision & Longevity: Manufactured to P4 tolerance and featuring a lightweight, durable phenolic resin cage, this bearing ensures smooth, quiet, and vibration-free operation, which is critical for precision applications.
Lubrication & Temperature Range: The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C, suitable for a wide array of industrial environments.
7006 ACB/HCP4A Bearing Typical Application Areas
