7005 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7005 CE/P4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing, it excels at handling combined loads (simultaneous radial and axial loads) with its 15° contact angle. Manufactured to P4 (ABEC-7) tolerance class, it guarantees minimal runout and vibration, making it ideal for high-speed operation up to 46,000 rpm. Its phenolic resin cage and pre-lubrication contribute to smooth, quiet, and reliable performance in demanding environments.
7005 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a high-capacity design with optimized internal geometry, typically featuring a larger ball size and quantity for increased load ratings. |
| P4 | Specifies the tolerance class equivalent to ABEC-7, denoting very high precision in dimensions and running accuracy. |
| BVG275 | Denotes a specific preload level and internal clearance group. "VG275" typically refers to a light preload, enhancing rigidity and rotational accuracy for high-speed applications. |
7005 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4 tolerance class and specified preload (BVG275) work in tandem to provide exceptional shaft positioning accuracy and system stiffness, minimizing deflection under load.
- Superior Load Capacity: The CE high-capacity design, featuring 14 balls of 6.35 mm diameter, results in a high dynamic load rating of 1872 lbf and static load rating of 934 lbf, enabling reliable performance under significant combined loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the 15° contact angle and pre-lubrication are optimized for stable operation at the limiting speed of 46,000 rpm.
- Durable Material Construction: Rings and balls made from chrome steel provide high hardness, wear resistance, and a long operational life.
7005 CE/P4BVG275 Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance machinery requiring speed, accuracy, and rigidity. Key applications include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Gearboxes: Especially in robotics and aerospace actuation systems.
- High-Frequency Motors and Spindles: Used in PCB drilling and semiconductor manufacturing equipment.
- Medical Equipment: Such as high-speed dental handpieces and centrifuges.
- Turbochargers and Compressors: Where high rotational speeds are critical.
