7013 ACE/HCP4AQBCB Bearing Product Overview & Core Advantages
The 7013 ACE/HCP4AQBCB is a high-precision quadruplex matched bearing set designed for demanding applications requiring exceptional rigidity and accuracy. This metric angular contact ball bearing configuration features a back-to-back arrangement (QBC) and is manufactured to P4A tolerance class for superior running accuracy. Its core advantages include the ability to handle combined loads (radial and axial) simultaneously, providing high rigidity and stable rotational characteristics under complex loading conditions. The use of ceramic balls and a phenolic cage contributes to its high-speed capability and reduced weight, making it ideal for high-performance, high-reliability machinery.
7013 ACE/HCP4AQBCB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing series, defining the standard boundary dimensions: 65 mm bore, 100 mm OD, 72 mm width. |
| ACE | Indicates a 25° contact angle and light preload (Class B). |
| HC | Signifies the use of Hybrid Ceramic balls (ceramic balls with steel rings). |
| P4A | Denotes a high-precision tolerance class superior to ABEC 7, ensuring minimal runout and vibration. |
| QBC | Specifies the Quadruplex Back-to-Back matched arrangement of four bearings. |
7013 ACE/HCP4AQBCB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The quadruplex back-to-back (QBC) arrangement creates a highly rigid bearing system that effectively resists moment loads and supports combined radial and axial loads. The 25° contact angle is optimized for sustaining significant axial loads.
- High-Speed Performance: The combination of hybrid ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic resin cage allows for a high limiting speed of 31,000 rpm. This design minimizes friction and heat generation.
- Precision Operation: Manufactured to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, this bearing set ensures exceptional running accuracy, low noise, and minimal vibration.
- Pre-Lubricated for Immediate Use: The bearings are pre-lubricated, facilitating easy installation and providing immediate operational readiness within the specified temperature range.
