The 7208 B 2RS RICH is a high-performance single row angular-contact ball bearing specifically designed for applications where robust axial support is needed alongside radial load capacity. The designation B signifies a large 40° contact angle, making this bearing exceptionally suited for managing heavy axial loads in one direction, as well as combined radial and axial forces. With precise dimensions of 40 mm bore, 80 mm outer diameter, and an 18 mm width, it is widely used in machine tool mechanisms, pumps, and automotive applications. The suffix 2RS indicates the presence of double-sided rubber contact seals, which securely retain the pre-filled grease and offer reliable protection against dust, dirt, and moisture, ensuring an extended, maintenance-free operational life.
Key Performance Advantages:
- High Axial Load Capacity: The 40° contact angle (B) is optimized for sustaining substantial unidirectional axial forces.
- Sealed and Pre-Lubricated: Features double-sided contact rubber seals (2RS) for maximum contaminant exclusion and long service life.
- Versatile Combined Load Support: Delivers high running accuracy and stability under high radial and axial stress.
- RICH Quality: A durable component built for precise and reliable performance in demanding environments.
