311MFG Bearing Product Overview & Core Advantages
The 311MFG metric ball bearing is a single row radial bearing engineered for reliable performance in general industrial applications. Constructed entirely from chrome steel, it offers a robust solution for carrying primarily radial loads. Its open design allows for versatile lubrication options, while the ABEC 1 (ISO P0) tolerance class ensures consistent quality and dependable operation. This bearing is characterized by its high radial dynamic load rating of 17,805 lbf and a limiting speed of 6,300 rpm, making it a cost-effective and durable choice for a wide range of machinery.

| Code Segment | Technical Meaning |
|---|---|
| 311 | Standard bore diameter series code, indicating a 55mm bore. |
| MFG | Manufacturer's specific designation for this bearing series. |
| (No Seal Suffix) | The absence of a seal suffix denotes an open bearing, allowing for external lubrication. |
| (No Cage Suffix) | Indicates a standard pressed steel cage, providing a balance of strength and speed capability. |
311MFG Bearing Structural Features & Performance Benefits
Single Row Design: The fundamental ball bearing construction provides a compact and efficient solution for radial load support, contributing to the bearing's overall high rigidity.
Chrome Steel Construction: All components, including the rings, balls, and cage, are manufactured from chrome steel, ensuring high durability, wear resistance, and a long operational lifespan.
Open Seal Type: The open design is advantageous for applications where the bearing can be integrated into a centralized lubrication system or where specific lubricants are required for extreme operating conditions.
Standardized Internal Clearance: The CN radial internal clearance is a standard grade suitable for most common operating conditions, ensuring predictable performance and ease of replacement.
