7007/VA9D1 Bearing Product Overview & Core Advantages
The 7007/VA9D1 is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4 tolerance class, it excels in high-speed scenarios with a limiting speed of 56,000 rpm. Its key advantage lies in its ability to accommodate combined radial and axial loads simultaneously, making it an ideal, compact solution for high-performance spindles and precision machinery where reliability is paramount.
7007/VA9D1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Standard bearing series designation, indicating a 35mm bore, 62mm OD, and 14mm width. |
| VA9D1 | Indicates a Universal Matchable (SU) bearing. This suffix signifies that the bearing is part of a pre-manufactured, precision-matched set of 2 bearings, designed to be mounted in a specific arrangement (e.g., back-to-back or face-to-face) to achieve optimal preload and system rigidity. |
7007/VA9D1 Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: Manufactured to a P4 tolerance class with a 25° contact angle, this bearing provides superior running accuracy and stiffness, essential for minimizing deflection under load.
- Optimized for High-Speed Operation: The phenolic resin cage is lightweight and robust, contributing to lower friction and enabling the high limiting speed of 56,000 rpm.
- Superior Load Capacity: With a dynamic load rating of 3330 lbf and a static load rating of 2025 lbf, it is engineered to handle significant combined loads.
- Universal Matching Design: The Universal Matchable (SU) feature ensures that bearings are supplied as a pre-matched pair, guaranteeing consistent preload and performance without the need for selective assembly, simplifying installation and enhancing system reliability.
