6311 JEM Bearing Product Overview & Core Advantages
The 6311 JEM is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. As a metric bearing with an open design, it excels at handling radial loads while also accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision and operational consistency. Its robust construction from chrome steel ensures high durability and a long service life, making it a cost-effective solution for a wide range of machinery.
6311 JEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Standard bearing series designation indicating a medium duty, single row deep groove ball bearing with a 55mm bore. |
| JEM | Manufacturer-specific suffix. Please consult JEM's technical documentation for precise design details. |
Key Configuration: The bearing features an open seal type, meaning it is unsealed and requires an external sealing arrangement in contaminated environments. It comes with no pre-applied lubrication (lubrication: None), allowing for the selection of a specialized lubricant based on the specific application requirements.
6311 JEM Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings of 16,096 lbf and radial static load ratings of 10,116 lbf, ensuring reliable performance under significant stress.
- Precision & Stability: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing provides consistent running accuracy and smooth operation, minimizing vibration and noise.
- Robust Material Construction: All core components, including the rings, balls, and cage, are made from high-grade chrome steel. This material choice provides excellent hardness, wear resistance, and a long operational lifespan.
- High-Speed Capability: With a limiting speed of 5,600 rpm, the 6311 JEM is suitable for applications requiring rapid rotation, supported by its stable cage design and precise manufacturing.
