6217-2RS1/GJN Bearing Product Overview & Core Advantages
The 6217-2RS1/GJN is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core advantage lies in its sealed construction (2RS1) which provides robust protection against contaminants, making it suitable for environments where cleanliness is critical. This bearing is engineered to handle primarily radial loads with high efficiency, featuring a CN radial internal clearance and ABEC 1 (ISO P0) precision class, offering a dependable balance of performance and value for a wide range of industrial machinery.
6217-2RS1/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6217 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 85mm bore, 150mm OD, and 28mm width. |
| 2RS1 | Sealing Type | Features contact rubber seals on both sides. This provides superior sealing effectiveness compared to non-contact shields, protecting against dust and moisture ingress. |
| GJN | Lubrication | Indicates the bearing is pre-lubricated with a specific, high-quality grease. This grease is optimized for the temperature range of -30°C to 120°C, offering long-term, maintenance-free operation. |
6217-2RS1/GJN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 double rubber seals ensure excellent contamination exclusion, significantly extending bearing service life in harsh conditions and reducing the need for maintenance.
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 18,884 lbf and a radial static load rating of 13,916 lbf, ensuring durability under significant stress.
- Optimized for Standard Applications: With a CN standard radial internal clearance and ABEC 1 precision, it provides reliable, smooth operation for a vast majority of industrial uses without the cost of ultra-high precision grades.
- Maintenance-Free Operation: The combination of effective sealing and factory-applied grease (GJN) creates a closed, lubricated system, making the bearing ready for installation and long-term use without re-lubrication.
6217-2RS1/GJN Bearing Typical Application Areas
