6011NR/C3 Bearing Product Overview & Core Advantages
The 6011NR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications requiring reliable radial load capacity and precise operation. This metric bearing features an integral snap ring groove on its outer ring, enabling simplified axial positioning and secure housing mounting. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it is optimized for applications with elevated operational temperatures or where interference fits are used, ensuring consistent performance under demanding conditions.
6011NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6011 | Standard bearing series designation indicating dimensions: 55mm bore, 90mm OD, 18mm width. |
| NR | Snap Ring groove on the outer ring. This feature allows for axial location and simplifies housing design by eliminating the need for separate end caps or complex machining. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, high-speed operation, or heavy interference fits, preventing premature failure due to excessive preload. |
6011NR/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 6362 lbf and a static load rating of 4766 lbf, this bearing is designed to handle significant radial loads in continuous operation, ensuring long service life.
- Snap Ring Locating Feature: The integrated snap ring groove provides a cost-effective and space-saving solution for axial positioning within the housing, enhancing assembly efficiency and mechanical stability.
- Optimized for Thermal and Interference Conditions: The C3 clearance is a key performance feature, accommodating shaft and housing expansions under thermal stress, which prevents binding and maintains smooth rotation.
- High-Speed Capability: A limiting speed of 7,500 rpm is supported by the precision-ground chrome steel components and robust cage design, making it suitable for a wide range of industrial drives and motors.
- Open Design for Custom Lubrication: The open seal type allows for the application of specialized lubricants tailored to specific operational environments, from standard greases to high-temperature or food-grade options.
