Its open design and optimized internal geometry contribute to high operational reliability, making it an ideal choice for applications requiring precise rotational motion and robust performance under significant radial stresses.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61876 | Basic series designation for a deep groove ball bearing with a 380mm bore. |
| M | Indicates the use of a machined brass cage (inferred from common suffix usage), offering high strength and excellent guidance at moderate speeds. |
| A | Internal design modifications for optimized load distribution and performance. |
61876 MA Bearing Structural Features & Performance Benefits
- High Load Capacity: The robust single row construction, combined with high-grade chrome steel rings and balls, provides a high radial dynamic load rating of 54,404 lbf and a radial static load rating of 87,675 lbf, ensuring durability under heavy loads.
- Precision & Stability: Manufactured to P6 tolerance class with a CN radial internal clearance, this bearing guarantees precise shaft guidance, reduced vibration, and consistent performance.
- Optimized Cage Design: The stainless steel cage ensures low friction, excellent corrosion resistance within the cage structure, and reliable ball guidance, contributing to smooth operation.
- Versatile Operating Range: With a temperature range from -30°C to 120°C, the bearing is suitable for a wide array of industrial environments.
- Open Design: The open seal type allows for easy re-lubrication and is ideal for applications where external sealing is provided by the housing, facilitating optimal heat dissipation.
61876 MA Bearing Typical Application Areas
This bearing is designed for heavy-duty machinery and precision equipment, including:
- Industrial Gearboxes and large power transmission systems.
- Large Electric Motors requiring high radial load support.
