6313 NR Bearing Product Overview & Core Advantages
The 6313 NR is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Its core advantage lies in its integrated snap ring (fitted) on the outer ring, which simplifies axial location within a housing, reduces assembly costs, and allows for more compact housing designs. Manufactured to P0 tolerance class, this bearing offers reliable operation and is capable of handling significant radial loads, making it a robust and cost-effective solution for a wide range of machinery.

6313 NR Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The pre-fitted snap ring (NR) eliminates the need for complex housing shoulders or end caps, facilitating easier installation and disassembly. This feature is critical for achieving compact designs and reducing overall manufacturing costs.
- High Load Capacity: With a dynamic load rating of 21,919 lbf and a static load rating of 13,489 lbf, this bearing is engineered to handle substantial radial forces, ensuring long service life in strenuous applications.
- Robust Material Construction: The rings and balls are made from high-quality Chrome Steel for durability and wear resistance. The stainless steel cage provides strength and corrosion resistance, contributing to stable operation at the limiting speed of 6,700 rpm.
- Standard Precision & Clearance: Manufactured to P0 (Normal) tolerance and standard CN radial internal clearance, this bearing offers a reliable and cost-effective balance of precision and performance for general industrial use.
