61944 MA Bearing Product Overview & Core Advantages
The 61944 MA is a single row deep groove ball bearing engineered for high-performance applications requiring exceptional precision and reliability. Designed to primarily accommodate radial loads, this bearing features a P6 tolerance class for superior running accuracy and dimensional stability. Its open design allows for versatile lubrication options, making it suitable for high-speed operation up to 3,600 rpm. Constructed entirely from high-grade chrome steel with a stainless steel cage, it offers excellent durability and consistent performance in demanding environments.
61944 MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61944 | Basic bearing series and size designation. |
| M | Indicates the use of a machined brass cage (in this context, the specification indicates a stainless steel cage, which offers similar high-speed and temperature resistance benefits). |
| A | Internal design modifications for optimized internal geometry and performance. |
61944 MA Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing ensures minimal runout and precise shaft positioning, contributing to overall system high rigidity and smooth operation.
- Superior Load Capacity: With a dynamic load rating of 33,946 lbf and a static load rating of 40,466 lbf, it is built to handle significant radial loads reliably.
- Optimized High-Speed Performance: The combination of the stainless steel cage and open seal type allows for efficient lubrication management, enabling a high limiting speed and stable operation at 3,600 rpm.
- Robust Material Construction: Rings and balls made from chrome steel provide high hardness and wear resistance, while the stainless steel cage ensures corrosion resistance and dimensional stability across the operating temperature range of -30°C to 120°C.
