7013 ACE/HCP4BVG275 Bearing Product Overview & Core Advantages
The 7013 ACE/HCP4BVG275 is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single-row bearing features a 25° contact angle and is supplied with a preload, delivering superior running accuracy and high rigidity. Its construction with a phenolic cage and ceramic balls enables outstanding high-speed performance, making it an ideal solution for machine tool spindles and other precision machinery where reliability under combined loads is critical.
7013 ACE/HCP4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Standard bearing series designation, indicating a 65mm bore, 100mm OD, and 18mm width. |
| ACE | Internal design code, typically signifying optimized internal geometry and a 25° contact angle. |
| HC | Hybrid Ceramic: Denotes the use of ceramic balls, which reduce friction, heat generation, and allow for higher speeds. |
| P4 | Tolerance Class P4 (ABEC-7), indicating very high dimensional and running precision. |
| BVG275 | Lubrication code, specifying a high-performance grease suitable for the specified temperature range and high-speed operation. |
7013 ACE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls (Si3N4) significantly reduces centrifugal forces, minimizes friction and heat buildup, and extends service life, especially in high-speed applications.
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction at high rotational speeds, contributing to the bearing's high limiting speed of 20,000 rpm.
- 25° Contact Angle & Preload: This configuration provides high rigidity and precise axial positioning, enabling the bearing to effectively handle combined radial and axial loads.
- Super-Precision P4 Tolerance: Ensures minimal runout and vibration, which is essential for applications demanding extreme running accuracy and smooth operation.
- Optimized Lubrication: Pre-lubricated with a specialized grease (BVG275) that performs reliably within a temperature range of -30°C to 110°C.
7013 ACE/HCP4BVG275 Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Robotic Drives and Servo Motors
- High-Frequency Spindles for PCB drilling and routing
- Aerospace & Defense Systems (Gyroscopes, navigation instruments)
