694 2rs Bearing Product Overview & Core Advantages
The 694 2RS is a sealed miniature deep groove ball bearing designed for compact applications requiring reliable performance. This single row metric bearing excels in handling radial loads while its integrated sealing provides excellent contamination protection. Engineered with chrome steel components and precision ABEC1 tolerances, it delivers consistent operation in demanding environments. Its compact dimensions (4mm bore × 11mm OD × 4mm width) make it ideal for space-constrained assemblies where high rotational speeds (up to 48,000 rpm) and long service life are critical requirements.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 694 | Standard series designation for miniature deep groove ball bearings | Industry-standard dimensions and interchangeability |
| 2RS | Double rubber contact seals on both sides | Superior protection against contaminants and moisture retention |
694 2rs Bearing Structural Features & Performance Benefits
Optimized Sealing System: The Nitrile rubber (2RS) contact seals provide effective barrier against dust, moisture, and other contaminants while retaining lubrication. This design ensures extended service intervals and reliable operation in challenging environments.
Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial internal clearance (0.002-0.013mm), this bearing delivers smooth operation and consistent performance across its operating temperature range of -30°C to 110°C.
Enhanced Load Capacity: With a dynamic load rating of 183 lbf and static load rating of 63 lbf, the bearing handles significant radial loads despite its miniature size. The deep groove raceway design optimizes stress distribution for improved durability.
High-Speed Capability: The stainless steel cage and precision-balanced design enable operation at limiting speeds up to 48,000 rpm, making it suitable for high-speed miniature applications.
Material Excellence: Constructed from chrome steel rings and balls with stainless steel cage, the bearing offers excellent wear resistance and corrosion protection, ensuring long-term reliability.
