6211-2Z/C3GJN 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 primarily radial loads, while also accommodating moderate axial loads in both directions. Its key advantages include a C3 radial internal clearance for stable operation under thermal expansion, and pre-lubrication for long-term, maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and high reliability in a compact design.
6211-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6211 | Basic series: 60 series deep groove ball bearing with 55mm bore | Standardized dimensions for easy replacement |
| 2Z | Double-sided steel shields | Contaminant protection while maintaining low friction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed or high-temperature applications |
6211-2Z/C3GJN Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial dynamic load rating of 9757 lbf and radial static load rating of 6609 lbf, making it suitable for moderate to heavy-duty applications.
Enhanced Contamination Resistance: The double-sided steel shields (2Z) provide effective protection against particulate contamination while minimizing friction, contributing to the limiting speed of 6,300 rpm.
Thermal Stability: The C3 radial clearance ensures reliable operation across the temperature range of -30°C to 120°C, preventing binding due to thermal expansion.
Durable Construction: All-steel construction using chrome steel for rings, balls, and cage provides consistent performance and long service life.
