7013 CD/HCP4ADBC Bearing Product Overview & Core Advantages
The 7013 CD/HCP4ADBC is a precision duplex angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. This matched back-to-back (DB) arrangement is preloaded to Moderate Class C, providing superior stiffness and rotational accuracy for handling combined loads (radial and axial) simultaneously. Featuring a ceramic ball and phenolic cage construction, it is engineered for high-speed operation up to 31,000 rpm, making it an ideal solution for high-performance machinery requiring reliable, long-term operation.
7013 CD/HCP4ADBC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing series and size designation (65mm bore, 100mm OD). |
| CD | Indicates a duplex pair in a back-to-back (DB) arrangement. |
| HC | Signifies the use of hybrid ceramic balls (Silicon Nitride). |
| P4A | Denotes a high precision tolerance class, superior to ABEC 7. |
| DBC | Specifies a moderate preload (Class C) applied to the duplex set. |
7013 CD/HCP4ADBC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back configuration creates a wide, stable support system that significantly increases moment rigidity, enabling the bearing to withstand heavy combined loads and complex force scenarios effectively.
Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage reduces centrifugal forces and inertial friction, allowing for the high limiting speed of 31,000 rpm. The standard 15° contact angle provides an excellent balance between radial and axial load capacity at speed.
Precision & Longevity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration for ultra-precise applications. The open design allows for custom lubrication schemes tailored to specific operational environments within the specified temperature range.
