6302 TN9/C4 Bearing Product Overview & Core Advantages
The 6302 TN9/C4 is a single row deep groove ball bearing designed for precision applications requiring exceptional performance under radial loads. Featuring a C4 radial internal clearance and TN9 nylon cage, this metric bearing delivers reliable operation in applications with thermal expansion requirements. Manufactured from chrome steel with ABEC 1 | ISO P0 tolerance class, it ensures consistent performance in demanding industrial environments while maintaining high rotational accuracy.
6302 TN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| TN9 | Nylon cage, glass fiber reinforced | Enables higher limiting speeds (17,000 rpm) with reduced friction and excellent acceleration characteristics |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with significant temperature variations |
6302 TN9/C4 Bearing Structural Features & Performance Benefits
Optimized Cage Design: The TN9 nylon cage provides excellent strength-to-weight ratio, contributing to reduced centrifugal forces and enabling operation at the high limiting speed of 17,000 rpm.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional control (bore diameter: 15 mm, outside diameter: 42 mm, width: 13 mm), ensuring consistent performance and easy installation.
Enhanced Load Capacity: With a radial dynamic load rating of 2563 lbf and radial static load rating of 1225 lbf, this bearing delivers reliable performance under substantial radial loads.
Thermal Compensation: The C4 radial internal clearance accommodates differential thermal expansion between shaft and housing, preventing premature failure in temperature-varying applications.
