7011 CD/HCP4ADGB Bearing Product Overview & Core Advantages
The 7011 CD/HCP4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed capability. As a universal matchable (SU) bearing supplied in a pre-loaded pair, it delivers superior high rigidity and stable running performance. Its construction with ceramic balls and a phenolic cage enables operation at limiting speeds up to 34,000 rpm, making it an ideal solution for high-performance spindles and other precision machinery.
7011 CD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
- 7011: Basic designation indicating a 55mm bore, 90mm OD, and 36mm width
- C: 15° contact angle
- D: Light preload (Class B)
- HC: Hybrid Ceramic construction (steel rings with ceramic balls)
- P4A: High precision tolerance class equivalent to ABEC 7
- ADGB: Universal matchable (SU) designation, supplied as a pre-adjusted pair
7011 CD/HCP4ADGB Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and silicon nitride ceramic balls significantly reduces centrifugal forces, enabling higher operating speeds while providing electrical insulation and extended service life.
Pre-loaded Universal Match: As a universally matchable (SU) pair with light preload, these bearings deliver immediate high rigidity without requiring additional adjustment, ensuring precise shaft positioning and minimal runout.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and operates effectively at high speeds, while the 15° contact angle optimizes the balance between radial and axial load capacity for high-speed applications.
Precision Performance: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring consistent high-precision performance in demanding applications.
