7006 ACEGA/HCP4AL1 Bearing Product Overview & Core Advantages
The 7006 ACEGA/HCP4AL1 is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single bearing features an extra light preload (Class A) and is manufactured to P4A super-precision tolerance, ensuring smooth, quiet operation with minimal runout. Its ceramic balls and phenolic cage contribute to superior high-speed capabilities and reduced rotational mass. Designed to handle combined radial and axial loads simultaneously, it offers outstanding rigidity and operational reliability in precision systems.
7006 ACEGA/HCP4AL1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |

| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 13mm width). |
| AC | Angular Contact design with a 25° contact angle. |
| EGA | Designates a Universal Matchable (SU) bearing, supplied in a set of 4 for precise preload configuration. |
| HC | Indicates the use of Hybrid Ceramic balls (ceramic balls with steel rings). |
| P4A | Specifies the super-precision tolerance class, exceeding ABEC 7 standards. |
| L1 | Identifies the light preload category applied to the bearing. |
7006 ACEGA/HCP4AL1 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) ceramic balls significantly reduces friction, heat generation, and wear. This construction enables higher limiting speeds (71,500 rpm), provides electrical insulation, and extends service life, especially in contaminated or poorly lubricated environments.
Phenolic Resin Cage: The lightweight and robust phenolic cage offers excellent dimensional stability and low friction at high rotational speeds, contributing to the bearing's overall high-speed performance and smooth operation.
Precision & Rigidity: Manufactured to P4A tolerance with an extra light preload, this bearing delivers exceptional running accuracy and system rigidity. This minimizes deflection under load, making it ideal for applications where precise shaft positioning is critical.
Universal Matching Design (SU): Supplied as a set of four universally matchable bearings, they can be arranged in various configurations (back-to-back, face-to-face, or tandem) to achieve the desired preload and stiffness for the specific application without selective mounting.
