7220 BEGAY Bearing Product Overview & Core Advantages
The 7220 BEGAY is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. Manufactured to P6 (ABEC-3) tolerance class, this single-row bearing excels in handling combined loads, offering superior support for both radial and significant axial loads in one direction. Its optimized 40° contact angle and robust construction using chrome steel components ensure high rigidity and operational reliability in demanding environments.
7220 BEGAY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Designates an increased 40° contact angle, optimized for higher axial load capacity. |
| GA | Indicates the bearing is supplied with a light preload for enhanced stiffness and precise shaft positioning. |
| Y | Specifies a special cage design and/or material, in this case a brass cage for superior high-speed performance and durability. |
7220 BEGAY Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row design with a 40° contact angle provides excellent resistance to combined loads, ensuring stable operation under high radial and one-direction axial forces. The light preload (GA) further enhances system rigidity.
- High-Speed Performance: The brass cage (Y) offers excellent strength and low friction, contributing to a high limiting speed of 4,500 rpm. The open design facilitates efficient lubrication management.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees precise running accuracy and minimal vibration, which is critical for high-performance machinery.
- Optimized Internal Geometry: Features like the specified shoulder diameters and chamfer dimensions ensure proper fitment and optimal load distribution.
7220 BEGAY Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for high-precision and high-speed applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Gearboxes
- Pumps and Compressors
- Robotic Arms and Precision Positioning Systems
