6211-2RSH Bearing Product Overview & Core Advantages
The 6211-2RSH is a single row deep groove ball bearing designed for high reliability and performance in demanding applications. This sealed bearing excels at handling primarily radial loads and offers robust operation due to its precision P6 tolerance class. Its key advantages include long service life facilitated by integrated seals and pre-lubrication, making it a maintenance-friendly and durable solution for a wide range of industrial machinery.
6211-2RSH Bearing Model Code Explained, Specifications & Naming Convention
The model number 6211-2RSH is decoded as follows:
- 6211: Standard designation for a single row deep groove ball bearing with a 55 mm bore, 100 mm OD, and 21 mm width.
- 2RSH: This suffix indicates the bearing features two (2) RSH-type contact seals. These seals are made of Nitrile Rubber (NBR) and provide superior protection against contamination and grease leakage compared to standard non-contact shields.
6211-2RSH Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: Constructed from chrome steel rings and balls, this bearing offers a high radial dynamic load rating of 10,386 lbf and a static load rating of 6,519 lbf, ensuring reliable performance under significant stress.
- Effective Sealing & Lubrication: The 2RSH seals effectively retain the factory-applied grease lubricant and exclude contaminants like dust and moisture. This design contributes to the bearing's maintenance-free characteristic over its operational life.
- Precision & Speed Performance: Manufactured to a P6 tolerance class and featuring a stainless steel cage, the bearing ensures smooth operation and stable running accuracy, suitable for applications with a limiting speed of 4,300 rpm.
- Standard Internal Clearance: The CN radial internal clearance is the standard for normal operating conditions, providing a balance between temperature management and running precision.
6211-2RSH Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- General industrial machinery requiring a reliable, sealed ball bearing.
