62311-2RS1 Bearing Product Overview & Core Advantages
The 62311-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliability. Its key advantage lies in its ability to accommodate high radial loads and moderate axial loads in both directions, making it an incredibly versatile component. The integrated contact seals (2RS1) and pre-lubrication with grease ensure long service life and minimal maintenance, providing a robust solution for various industrial machinery.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 62311 | Basic designation for a single row deep groove ball bearing with 55mm bore, 120mm OD, and 43mm width. | Standardized dimensions for easy interchangeability and selection. |
| 2RS1 | Designates two integral contact seals, one on each side. | Provides excellent protection against contaminants and retains lubricant, enhancing bearing life in harsh environments. |
62311-2RS1 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is precision-engineered to handle high radial dynamic load ratings of 16,074 lbf and radial static load ratings of 10,116 lbf efficiently.
High-Speed Capability: The combination of a stainless steel cage and optimized internal design contributes to a high limiting speed of 3,800 rpm, suitable for a wide range of operational speeds.
Sealed & Lubricated for Life: The 2RS1 seals effectively shield the internal components from dust, moisture, and other contaminants. Pre-filled with high-quality grease lubrication, the bearing operates reliably across a temperature range of -30°C to 120°C, offering a maintenance-free solution.
Precision & Rigidity: Manufactured to a P6 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth, precise rotation and contributes to the overall system rigidity.
