6307NR/C3 Bearing Product Overview & Core Advantages
The 6307NR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its snap ring groove on the outer ring, which facilitates secure axial positioning within a housing, simplifying assembly and enhancing operational reliability. Its C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and value for a wide range of machinery.
6307NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Advantage |
|---|---|---|
| 6307 | Standard bore diameter code (35 mm), outside diameter (80 mm), and width (21 mm). | Indicates standard bearing dimensions for easy interchangeability and sourcing. |
| NR | Snap Ring groove on the outer ring. | Provides a positive locating feature, reducing housing design complexity and cost. |
| C3 | Greater than normal radial internal clearance. | Accommodates shaft and housing fits, and thermal expansion, preventing preload and ensuring smooth operation. |
6307NR/C3 Bearing Structural Features & Performance Benefits
The 6307NR/C3 leverages a single row deep groove raceway design, optimized for carrying significant radial loads. The incorporation of a snap ring (fitted) on the outer ring is a key structural feature that provides secure axial location, enhancing the bearing's stability in the housing. The C3 clearance is a critical performance attribute, ensuring reliable operation in applications prone to thermal gradients or where tight fits are employed. The all-chrome steel construction (rings, balls, and cage) ensures high strength and durability, contributing to a long service life under the specified temperature range of -30°C to 120°C. With a limiting speed of 8,500 rpm and a radial dynamic load rating of 7,509 lbf, it delivers a robust performance profile for general industrial use.
