6207 ETN9/C3 Bearing Product Overview & Core Advantages
The 6207 ETN9/C3 is a single row deep groove ball bearing engineered for precision applications requiring high rotational accuracy and reliability. This metric bearing features a P6 tolerance class for superior dimensional consistency and CN radial internal clearance (C3) providing optimal performance under thermal expansion conditions. Its open design with nylon cage enables high-speed operation up to 13,000 rpm while maintaining stable performance across a wide temperature range (-30° to 120°C). The bearing's optimized geometry delivers excellent radial load capacity (7014 lbf dynamic / 3957 lbf static) in a compact 35mm bore configuration.

6207 ETN9/C3 Bearing Structural Features & Performance Benefits
Optimized Raceway Geometry: The deep groove raceway design ensures smooth operation and efficient radial load distribution, minimizing stress concentrations and extending service life.
High-Speed Nylon Cage: The ETN9 polyamide cage provides superior guidance for rolling elements, reducing centrifugal forces and enabling stable operation at limiting speeds of 13,000 rpm.
Precision Manufacturing: Manufactured to P6 tolerance class with tight dimensional controls (bore tolerance: -0.01mm to 0), ensuring consistent performance in precision applications.
Thermal Compensation: The C3 radial clearance accommodates differential thermal expansion between shaft and housing, maintaining optimal preload conditions across the operating temperature range.
Chrome Steel Construction: High-grade chrome steel rings and balls provide excellent wear resistance and fatigue strength for extended bearing service life.
