7004 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7004 CE/P4BVG275 is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. As a P4 (ABEC-7) tolerance class bearing, it is designed to operate with minimal runout and vibration. Its key advantage lies in its ability to support combined loads, efficiently handling both radial and significant axial loads in one direction. The combination of a phenolic resin cage, a 15° contact angle, and preload availability makes this bearing an excellent choice for high-speed applications requiring high rigidity and operational stability.
7004 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
The model number 7004 CE/P4BVG275 provides detailed technical specifications. Below is a breakdown of its suffix codes:
- 7004: Basic designation indicating a metric, single-row angular contact ball bearing with a 20mm bore.
- C: Denotes a 15° contact angle, optimized for high-speed operation.
- E: Indicates reinforced design, featuring a larger ball set and optimized raceway geometry for increased load capacity.
- P4: Specifies the tolerance class equivalent to ABEC-7, ensuring ultra-high precision.
- BVG275: This suffix indicates the bearing is supplied lubricated with a specific high-performance grease suitable for the specified temperature range.
7004 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance standards, this bearing ensures exceptional dimensional accuracy and minimal vibration. The 15° contact angle and preload capability contribute to a stiff bearing arrangement, crucial for applications where shaft displacement must be minimized.
- Optimized for High-Speed Operation: The lightweight phenolic resin cage is engineered for high mechanical strength and low friction, enabling the bearing to achieve a high limiting speed of 54,000 rpm. This makes it ideal for high-speed spindles and precision machinery.
- Superior Load Capacity: The C and E design incorporates a larger ball complement and optimized internal geometry, resulting in high dynamic and static load ratings for its compact bearing dimensions (20mm bore x 42mm OD x 12mm width).
- Ready-to-Install: The bearing is supplied lubricated from the factory, simplifying installation and ensuring immediate, reliable performance.
7004 CE/P4BVG275 Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles
- High-Speed Grinding & Milling Heads
- Precision Robotics & Automation Equipment
- High-Frequency Motors
- Medical & Dental Handpieces
- Aerospace Instrumentation
