6318-2RS1 Bearing Product Overview & Core Advantages
The 6318-2RS1 is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its sealed construction provides robust protection against contaminants, while the P6 tolerance class ensures high running accuracy. This bearing excels at handling primarily radial loads and offers a high limiting speed, making it a versatile and durable solution for industrial machinery requiring long service life and minimal maintenance.
6318-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6318 | Basic Bearing Number | Defines the standard dimensions: 90mm bore, 190mm OD, 43mm width. |
| 2RS1 | Contact Seals on Both Sides | Features two synthetic rubber seals (RS1) that provide superior sealing effectiveness compared to metal shields, effectively retaining lubricant and excluding moisture and debris. |
6318-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals on both sides offer excellent protection, making the bearing suitable for environments with potential contamination. This design ensures the grease lubrication is retained, promoting a long, maintenance-free service life.
- High Load Capacity: Manufactured from chrome steel rings and balls, this bearing delivers a high radial dynamic load rating of 33,946 lbf and a radial static load rating of 24,279 lbf, providing reliable performance under significant stress.
- Precision & Stability: The P6 tolerance class offers tighter dimensional control than standard bearings, resulting in reduced vibration and more precise operation. The standard CN radial internal clearance is suitable for most common applications.
- Optimized for Speed: The stainless steel cage ensures stability and reduces friction at high rotational speeds, supporting the bearing's limiting speed of 2,400 rpm.
6318-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust, sealed bearings.
