6211-2Z/C3HT Bearing Product Overview & Core Advantages
The 6211-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing excels at handling radial loads while offering moderate capacity for axial loads. Its key advantages include robust construction using chrome steel components, providing excellent durability and a long service life. The combination of C3 radial internal clearance and ABEC 1 precision makes it suitable for applications with moderate speed requirements and thermal expansion considerations, ensuring stable operation and high reliability.
Model Code Breakdown
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6211 | Basic bearing designation (55mm bore, 100mm OD) | Standard metric dimensions for easy interchangeability |
| 2Z | Double-sided steel shields | Effective contamination protection while maintaining low friction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with temperature variations |
6211-2Z/C3HT Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The raceway geometry enables smooth operation under radial loads and moderate axial loads in both directions, providing versatile load capacity.
Shielded Protection System: The double-sided steel shields (2Z) effectively retain lubricant and exclude contaminants, enhancing bearing life without significantly increasing friction.
Precision Chrome Steel Construction: All critical components (rings, balls, cage) are manufactured from chrome steel, ensuring high strength, wear resistance, and dimensional stability.
Enhanced Internal Clearance: The C3 radial clearance provides operational stability in applications subject to thermal expansion or where interference fits are used.
High-Speed Capability: With a limiting speed of 6,300 rpm, this bearing delivers reliable performance in moderate to high-speed applications.
