7013 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7013 CE/P4BVG275 is a single-row angular contact ball bearing engineered for applications demanding high precision and superior running accuracy. Designed to accommodate combined loads, it efficiently supports both radial and significant axial loads in one direction. Its P4 (ABEC-7) tolerance class ensures exceptional dimensional and rotational precision, making it ideal for high-speed spindles and other precision machinery. The bearing is preloaded and pre-lubricated, offering immediate high-performance operation with excellent rigidity and stability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing series and size designation (65mm bore, 100mm OD, 18mm width). |
| CE | Indicates a 15° contact angle and optimized internal design for high-speed operation. |
| P4 | Specifies the high-precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration. |
| BVG275 | Denotes a specific manufacturer's internal code for preload level and cage type (Phenolic). |
7013 CE/P4BVG275 Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The single-row angular contact design, combined with a specified preload, provides high axial and radial rigidity, minimizing deflection under load for superior positional accuracy.
Optimized Load Capacity: With a 15° contact angle, this bearing is engineered to handle combined radial and axial loads simultaneously. The high-grade chrome steel construction ensures a robust dynamic load rating of 4568 lbf and a static load rating of 3510 lbf.
High-Speed Performance: The lightweight and durable phenolic resin cage reduces centrifugal forces, enabling a high limiting speed of 19,000 rpm. The optimized internal geometry further enhances high-speed capability.
Ready-to-Install Operation: The bearing comes pre-lubricated, facilitating immediate startup and reliable performance within its specified temperature range of -30°C to 110°C.
