7010 CD/HCP4ADBA Bearing Product Overview & Core Advantages
The 7010 CD/HCP4ADBA is a precision angular contact ball bearing supplied as a duplex back-to-back (DB) matched set. Engineered for the most demanding applications, this bearing features an Extra Light (Class A) preload and a P4A super-precision tolerance class, ensuring exceptional running accuracy and minimal vibration. Its duplex DB arrangement provides high rigidity and excellent stability, making it ideally suited for machine tool spindles and other high-performance machinery requiring superior rotational accuracy under combined loads.
7010 CD/HCP4ADBA Bearing Model Code Explained, Specifications & Naming Convention
- 7010: Basic designation denoting a 50 mm bore and 80 mm outside diameter.
- C: Signifies a 15-degree contact angle.
- D: Indicates the bearing is part of a duplex (matched) pair.
- HC: Denotes a hybrid ceramic construction, featuring steel rings and ceramic balls.
- P4A: Identifies the tolerance class, specifying extremely tight dimensional and running accuracy standards.
- A: Specifies an Extra Light preload within the matched set.
- DB: Defines the Back-to-Back mounting arrangement of the duplex pair.
7010 CD/HCP4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists moment loads, ensuring exceptional operational stability for precision spindles.
Enhanced High-Speed Performance: The use of lightweight ceramic balls reduces centrifugal forces and internal friction, while the phenolic resin cage offers excellent strength-to-weight ratio and guidance. This combination significantly contributes to a high limiting speed of 46,000 rpm.
Superior Precision: Manufactured to P4A tolerance class with a controlled preload, this bearing guarantees minimal runout and superior rotational accuracy, which is critical for high-precision machining and finishing.
Reduced Heat Generation & Long Service Life: The hybrid ceramic design provides superior hardness, reduced thermal expansion, and electrically insulating properties, leading to lower operating temperatures, extended bearing service life, and improved reliability.
