6211 M Bearing Product Overview & Core Advantages
The 6211 M is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing is characterized by its high radial load capacity and ability to accommodate moderate axial loads in both directions. Manufactured to P6 tolerance class, it ensures superior running accuracy, making it ideal for applications requiring high rotational precision and reliability. Its open design allows for versatile lubrication options, while the stainless steel cage contributes to its durability and high-speed capability.
6211 M Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6211 | Standard single row deep groove ball bearing with 55mm bore, 100mm OD, and 21mm width. |
| Cage Designation | M | Machined brass cage, offering high strength, excellent guidance, and suitability for high-speed operation and demanding conditions. |
6211 M Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The optimized raceway geometry and single row design provide a high radial dynamic load rating of 10,386 lbf and a radial static load rating of 6,519 lbf, ensuring stable performance under significant loads.
- Precision & Speed: Built to P6 tolerance class with a CN radial internal clearance, this bearing guarantees precise shaft guidance and low vibration. The machined brass (M) cage enables a high limiting speed of 13,000 rpm.
- Durability & Material Quality: Components made from chrome steel (rings and balls) provide high hardness and wear resistance. The stainless steel cage offers excellent corrosion resistance and mechanical strength.
- Versatile Application Range: The open seal type allows for the use of various lubricants to suit specific operational environments, supporting a wide temperature range from -30°C to 120°C.
