6311 Bearing Product Overview & Core Advantages
The 6311 is a metric single row deep groove ball bearing engineered for exceptional performance in a wide range of industrial applications. Its fundamental design is optimized to primarily support radial loads, while also accommodating moderate axial loads in both directions. Manufactured from high-grade Chrome Steel with an open design, this bearing is a versatile and cost-effective solution for general machinery requiring reliable operation and ABEC-1 precision. Its robust construction ensures dependable service in demanding environments.
6311 Bearing Model Code Explained, Specifications & Naming Convention
- 63: Series designation, indicating a medium width and a robust load-carrying capacity.
- 11: Bore diameter code. For this series, '11' corresponds to a 55 mm bore diameter.
- Open: The bearing features no seals or shields, allowing for high-speed operation and facilitating custom lubrication regimes.
- ABEC-1: Specifies the tolerance class, denoting standard precision suitable for most industrial applications.
- CN: Denotes the standard, normal radial internal clearance group.
6311 Bearing Structural Features & Performance Benefits
The performance of the 6311 bearing is a direct result of its thoughtful engineering:
- High Load Capacity: The deep groove raceway and single-row design provide a high dynamic load rating of 16,096 lbf and a static load rating of 10,116 lbf, enabling it to handle significant radial forces.
- Optimized for Speed: The stainless steel cage ensures stability and reduces friction, contributing to a high limiting speed of 5,600 rpm.
- Material Integrity: Constructed from Chrome Steel for both rings and balls, the bearing offers high hardness, wear resistance, and a long operational lifespan.
- Standard Precision: The ABEC-1 tolerance class guarantees consistent dimensional accuracy and smooth running, essential for reducing vibration and noise in machinery.
6311 Bearing Typical Application Areas
The 6311 is a workhorse component found in numerous sectors due to its reliability and versatility. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
- General Industrial Machinery requiring a 55 mm bore bearing.
