The 7200-B RICH is a high-precision single row angular-contact ball bearing engineered for applications demanding extreme speed and superior axial load support. The designation B indicates a large 40° contact angle, which is optimized for managing substantial unidirectional axial loads along with combined radial forces. With compact dimensions of 10 mm bore, 30 mm outer diameter, and a 9 mm width, this bearing is ideal for precise machinery, including machine tool spindles and high-speed rotary equipment. A critical feature is the high-performance Textolite cage, which is centered on the outer ring. This cage material and guidance method ensure lightweight operation, low friction, and excellent stability, making the 7200-B RICH particularly suitable for the most demanding, high-speed applications.
Key Performance Advantages:
- Extreme High-Speed Capability: Textolite cage construction and outer ring guidance ensure stability and minimal friction at very high RPM.
- Superior Axial Load Support: The 40° contact angle (B) efficiently handles heavy unidirectional axial loads.
- High Precision: Built for accurate shaft guidance and rotational performance.
- RICH Quality: A specialized component designed for peak performance and durability in precision machinery.
