The SS R-2 ZZ RICH is a precision-engineered miniature single row deep groove ball bearing manufactured from high-grade stainless steel. Designed for applications where corrosion resistance is paramount, this bearing features an inch-based dimension profile of 3.175 mm bore, 9.525 mm outer diameter, and 3.967 mm width. The stainless steel construction ensures reliable performance in humid or slightly corrosive environments, making it an ideal choice for medical instruments, laboratory equipment, and precision electronics.
To maintain high-speed efficiency while protecting internal components, the bearing is equipped with double-sided non-contact metal shields (ZZ). These shields provide a baseline defense against dust and debris without increasing rotational friction, allowing the bearing to maintain a high RPM capability. With its normal internal clearance (CN) and durable steel cage, the SS R-2 ZZ RICH offers smooth rotation and long-term stability for small-scale mechanical assemblies requiring rust-proof protection.
Key Performance Advantages:
- Corrosion Resistance: Stainless steel build prevents oxidation in moisture-rich environments.
- Low Friction ZZ Shields: Metal shields protect the raceways without compromising rotational speed.
- Miniature Precision: Compact design optimized for high-accuracy small devices.
- RICH Durability: Engineered for consistent performance and low vibration levels.
