6411 NR Bearing Product Overview & Core Advantages
The 6411 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding industrial applications. Its key distinguishing feature is the snap ring (fitted) on the outer ring, which simplifies axial location within a housing, reducing design complexity and assembly time. Manufactured from high-grade chrome steel with a stainless steel cage, it offers robust durability and consistent operation. This bearing is an open-type, P0 tolerance class component, making it a cost-effective and versatile solution for a wide range of machinery.

6411 NR Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The integrated snap ring eliminates the need for complex housing shoulders or end caps, providing a secure axial location and reducing overall system cost and weight.
- High Radial Load Capacity: The single row deep groove construction is optimized to handle significant radial loads (Dynamic: 22,368 lbf / Static: 13,938 lbf), ensuring stable performance under stress.
- Robust Material Construction: Rings and balls made from chrome steel (GCR15) provide high hardness and wear resistance. The stainless steel cage offers superior strength and corrosion resistance, enhancing bearing life.
- Standard Precision & Clearance: As a P0 tolerance class bearing with standard CN radial internal clearance, it delivers reliable and predictable performance for most industrial applications.
- Wide Temperature Range: Suitable for operating temperatures from -30°C to 120°C, accommodating various environmental conditions.
