S6909 Bearing Structural Features & Performance Benefits
All-Stainless Construction: The bearing rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making it suitable for harsh environments, including those requiring washdown or exposure to chemicals.
High-Speed Capability: The open design and precision-ground components enable a limiting speed of 9,000 rpm, making it suitable for high-velocity applications. The stainless steel cage ensures stability at elevated rotational speeds.
Radial Load Performance: With a dynamic load rating of 2853 lbf and a static load rating of 2205 lbf, this bearing is designed to handle significant radial forces, ensuring long service life and reliability.
Precision Engineering: Manufactured to ABEC-1 tolerance class with strict dimensional control on the bore diameter, outside diameter, and width, it delivers smooth, low-vibration, and low-noise operation.
S6909 Bearing Typical Application Areas
- Food Processing & Packaging Machinery (for corrosion resistance and washdown capability)
- Medical Equipment (for precision and biocompatible material)
- Chemical Handling Pumps & Mixers (for resistance to aggressive media)
- Precision Instruments & Optical Devices (for low vibration and high accuracy)
