61964 MA/C3 Bearing Product Overview & Core Advantages
The 61964 MA/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing features an open design and is manufactured to ABEC 1 | ISO P0 precision class, ensuring reliable operation and consistent quality. Its primary strength lies in its ability to accommodate high radial loads, with a substantial dynamic load rating of 62047 lbf. The optimized internal geometry, combined with a machined metal cage, contributes to stable operation and long service life, making it a robust and dependable choice for heavy-duty machinery.
61964 MA/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61964 | Basic bearing designation, indicating a deep groove ball bearing with a 320 mm bore and 440 mm outside diameter. |
| MA | Denotes a machined brass cage, providing high strength, excellent guidance, and suitability for high-speed applications. |
| C3 | Specifies a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, such as in electric motors or gearboxes, where it prevents preload and potential bearing seizure. |
61964 MA/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway and robust chrome steel construction enable high radial dynamic and static load ratings, providing dependable support in heavy-load scenarios.
- Optimized for Speed & Stability: The inclusion of a machined metal cage (MA) ensures precise ball guidance, reduces friction, and contributes to a higher limiting speed of 2,400 rpm, promoting smooth and stable operation.
- Operational Flexibility with C3 Clearance: The C3 radial internal clearance allows for thermal expansion of the shaft and housing, making this bearing ideal for applications where operational temperatures vary, thereby enhancing reliability and preventing premature failure.
- Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability, ensuring a long operational lifespan under continuous use.
