Key Performance Advantages:
- High-Temperature Reliability (C3): The increased internal clearance (C3) allows for thermal expansion during high-speed operation or in high-heat environments, ensuring the bearing won't seize and will maintain smooth rotation.
- Optimized Thin-Section Design: Part of the 6900/61900 series, this bearing offers an excellent strength-to-weight ratio, allowing for a large 30 mm shaft in a compact 47 mm housing.
- Hermetic 2RS Protection: The dual rubber contact seals (2RS) effectively shield the internal raceways from moisture, dust, and dirt, while keeping the high-grade grease locked inside for life.
- Precision and Quietness: Despite the larger clearance, the RICH precision manufacturing ensures low noise and vibration, making it suitable for electric bikes, fans, and precision automation.
- Versatile Installation: Frequently used in cycling (bottom brackets and hubs), electric motors, and robotics where space is at a premium.
