6212-2RS1 Bearing Product Overview & Core Advantages
The 6212-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. As a metric sealed bearing, its primary advantage lies in its ability to efficiently handle radial loads while offering reliable, long-term operation. The integrated contact seals (2RS1) and factory-applied grease lubrication provide excellent contamination protection, making it a maintenance-free solution. With a P6 tolerance class and standard CN radial internal clearance, this bearing delivers consistent, high-precision performance, ensuring reliability and durability in a wide range of industrial machinery.
6212-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6212 | Basic designation: 60mm bore, 110mm OD, 22mm width | Standard bearing dimensions for easy interchangeability. |
| 2RS1 | Two contact seals (one on each side) made of NBR rubber. | Superior protection against contaminants like dust and moisture; retains lubricant effectively. |
6212-2RS1 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings and balls, and featuring a stainless steel cage, the 6212-2RS1 offers a high radial dynamic load rating of 12,432 lbf and a static load rating of 8,093 lbf. This ensures reliable performance under significant radial stresses.
- Optimized Sealing & Lubrication: The 2RS1 contact seals provide an effective barrier, making the bearing ideal for environments with particulate matter or moisture. Pre-lubricated with grease, it operates smoothly within a temperature range of -30°C to 120°C and is effectively maintenance-free for its service life.
- Precision & Speed Performance: The P6 tolerance class ensures high running accuracy, while the design supports a limiting speed of 4,000 rpm. The standard CN radial internal clearance is suitable for most general industrial applications.
6212-2RS1 Bearing Typical Application Areas
The 6212-2RS1 is a versatile component found in numerous sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Pumps and Fans
- General machinery requiring a reliable, sealed radial ball bearing.
