61922 MA/W64 Bearing Product Overview & Core Advantages
The 61922 MA/W64 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing is designed primarily to handle radial loads with high efficiency and reliability. Its key advantages include a compact design, high limiting speed, and the integration of Soild Oil lubrication, which provides long-term, maintenance-free operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and is an ideal choice for applications requiring high reliability and dimensional stability.
61922 MA/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61922 | Basic series designation for a deep groove ball bearing with a 110mm bore and 150mm OD. |
| MA | Indicates a machined metal cage, typically brass or steel, offering high strength and suitability for high-speed applications. |
| W64 | Designates the Soild Oil lubrication system, a polymer matrix saturated with oil that ensures consistent lubrication and is ideal for applications where re-lubrication is difficult. |
61922 MA/W64 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is designed to support high radial dynamic load ratings (9802 lbf) and radial static load ratings (10116 lbf), making it robust for various load conditions.
High-Speed Capability: The combination of the machined metal cage (MA) and precision-ground chrome steel components enables a high limiting speed of 7,500 rpm, ensuring stable operation in demanding environments.
Maintenance-Free Operation: The integrated Soild Oil (W64) lubrication provides a consistent oil film over a wide temperature range (-30°C to 120°C), eliminating the need for re-lubrication and reducing maintenance costs.
Precision and Durability: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing offers reliable performance, low noise, and long service life.
