61964 MA Bearing Product Overview & Core Advantages
The 61964 MA is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing is designed to handle primarily radial loads with high efficiency and reliability. Manufactured to a P6 tolerance class, it guarantees superior running accuracy and dimensional consistency. Its open design allows for versatile lubrication options, making it suitable for high-speed operations up to 2,400 rpm. The use of high-grade chrome steel for rings and balls ensures excellent durability and a long service life, making it an ideal choice for applications requiring high precision and robust performance.
61964 MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61964 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 320mm bore. |
| M | Indicates the use of a machined brass cage, offering high strength and excellent performance at high speeds. |
| A | Signifies an enhanced internal design, typically optimizing load distribution and potentially increasing the dynamic load rating. |
61964 MA Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P6 tolerance class and precise bearing dimensions (320mm bore, 440mm OD) ensure minimal runout and vibration, providing stable and accurate rotation under load.
- Superior Load Capacity: With a radial dynamic load rating of 62,047 lbf and a radial static load rating of 89,924 lbf, this bearing is built to withstand significant radial forces in heavy-duty applications.
- Optimized High-Speed Performance: The machined brass cage (M) provides superior guidance and stability, contributing to the high limiting speed of 2,400 rpm.
- Robust Construction: Components made from chrome steel (rings, balls) and a stainless steel cage offer excellent resistance to wear and fatigue, ensuring long-term reliability.
- Standard Internal Clearance: The CN radial internal clearance is suitable for a wide range of common operating conditions and fits.
