6211N/C3 Bearing Product Overview & Core Advantages
The 6211N/C3 is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding industrial applications. This metric bearing features a snap ring groove on its outer ring, enabling secure axial location and simplified housing design. Manufactured to ABEC 1 | ISO P0 tolerance class with a C3 radial internal clearance, it delivers consistent operation under varying thermal conditions. Its open design allows for versatile lubrication options, making it a robust and cost-effective solution for a wide range of machinery.
6211N/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6211 | Basic bearing designation indicating a single row deep groove ball bearing with a 55mm bore, 100mm OD, and 21mm width. |
| N | Signifies the presence of a snap ring groove on the outer ring for secure axial positioning. |
| /C3 | Indicates a greater than normal radial internal clearance, suitable for applications with significant thermal expansion or where interference fits are used. |
6211N/C3 Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Secure Mounting: The outer ring's snap ring groove (N suffix) provides a positive locating feature, simplifying housing design and preventing axial displacement in the housing bore, which enhances operational reliability.
- Optimized Radial Load Capacity: The single row deep groove construction is engineered to handle significant radial loads efficiently, making it a fundamental component for shaft support.
- Versatile Operating Range: Manufactured from chrome steel for both rings and balls, the bearing offers high strength and durability across a wide temperature range from -30°C to 120°C.
- Adaptable Internal Clearance: The C3 clearance provides extra space between the rolling elements and raceways, accommodating shaft expansion or contraction under thermal gradients, thereby preventing pre-load and ensuring smooth operation.
- Open Design for Custom Lubrication: The open seal type allows for the application of various lubricants (grease or oil) tailored to specific speed, load, and environmental conditions, offering flexibility in maintenance regimes.
6211N/C3 Bearing Typical Application Areas
- Electric Motors and Generators: Ideal for supporting rotor shafts where radial loads are predominant and secure axial location is required.
- Industrial Gearboxes and Transmissions: Used in various stages for supporting gears and shafts, benefiting from its radial load capacity and C3 clearance for thermal management.
- Material Handling Equipment: Commonly found in conveyor pulleys and rollers, where the snap ring groove simplifies assembly and maintenance.
- Agricultural Machinery: Suitable for applications in tractors and harvesters that require robust bearings capable of withstanding shock loads and varying temperatures.
- General Industrial Machinery: A versatile choice for pumps, fans, and other machinery requiring reliable shaft support with a standard tolerance class.
