6011-ZNR/C3 Bearing Product Overview & Core Advantages
The 6011-ZNR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers a significant advantage with its snap ring fitted outer ring, which simplifies axial positioning and reduces housing machining costs. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise operation. The combination of shielded construction and a C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where higher operational speeds are required.
6011-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6011-ZNR/C3 provides detailed technical specifications through its suffixes:
- 6011: Basic designation indicating a single row deep groove ball bearing with a 55mm bore, 90mm OD, and 18mm width.
- Z: Denotes a shielded (non-contact) seal on one side, protecting the bearing interior from large contaminants while minimizing friction.
- NR: Indicates the outer ring features a snap ring groove and a fitted snap ring. This facilitates secure axial location within the housing.
- C3: Specifies a greater than normal radial internal clearance. This is ideal for applications involving thermal expansion, interference fits, or where a higher operational temperature is expected.
6011-ZNR/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing delivers a high radial dynamic load rating of 6362 lbf and a static load rating of 4766 lbf, ensuring durability under significant stress.
- Simplified Assembly & Positioning: The integrated snap ring (fitted) on the outer ring eliminates the need for complex housing shoulders, enabling easier installation and secure axial location, which is critical for maintaining alignment.
- Optimized for Challenging Conditions: The C3 clearance provides operational stability in environments prone to thermal expansion, preventing performance degradation due to preload from heated components.
- Contaminant Protection: The shielded (Z) design offers fundamental protection against large particulate contaminants, extending bearing life in moderately dirty environments without the torque increase associated with contact seals.
- Broad Operating Range: With a temperature range of -30°C to 120°C and a limiting speed of 7,500 rpm, it is versatile for a wide array of industrial applications.
6011-ZNR/C3 Bearing Typical Application Areas
The 6011-ZNR/C3 is ideally suited for applications requiring reliable radial support and simplified axial location. Key industries and equipment include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Any application where a snap ring is specified for housing design simplification.
