7013 CE/HCP4BVG275 Bearing Product Overview & Core Advantages
The 7013 CE/HCP4BVG275 is a single-row angular contact ball bearing engineered for applications demanding ultra-high precision and superior performance. Its defining features include a P4 (ABEC-7) tolerance class for exceptional running accuracy and a 15° contact angle optimized for handling combined radial and axial loads simultaneously. The use of ceramic balls and a phenolic cage contributes to lower friction, higher limiting speeds, and extended service life, making it an ideal choice for high-reliability, high-speed machinery.
7013 CE/HCP4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| CE | High-Precision, Low-Noise Design | Indicates optimized internal geometry for smooth, quiet operation at high speeds. |
| HC | Hybrid Ceramic (Ceramic Balls) | Utilizes silicon nitride balls for reduced weight, lower friction, and increased durability. |
| P4 | Tolerance Class (ABEC-7) | Guarantees extremely tight dimensional and running accuracy for precision applications. |
| BVG275 | Preload & Lubrication Specification | Specifies a light preload for enhanced rigidity and is pre-lubricated for immediate operation. |
7013 CE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces and operating temperatures, enabling a high limiting speed of 22,000 rpm. This also provides electrical insulation and superior resistance to wear.
- Phenolic Resin Cage: This lightweight, robust cage material offers excellent dimensional stability and low friction at high rotational speeds, contributing to the bearing's overall high-speed performance and smooth operation.
- Precision Engineering: Manufactured to P4 tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring high positional accuracy.
- Optimized Load Capacity: The 15° contact angle is designed to efficiently support substantial combined (radial and axial) loads, providing reliable performance in demanding conditions.
