| Code Segment | Technical Meaning |
|---|---|
| 7205 | Basic bearing series and size designation (25mm bore, 52mm OD) |
| BE | Designates 40° contact angle and optimized internal geometry |
| GA | Indicates brass cage construction for superior strength and guidance |
| Y | Specifies the bearing is pre-lubricated from the factory |
7205 BEGAY Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated shoulder diameters ensure optimal load distribution, enhancing bearing life and stiffness.
High-Speed Capability: The robust brass cage (GA) provides excellent stability and guidance for the ball complement, contributing to reliable operation at the limiting speed of 17,000 rpm.
Superior Load Capacity: With a dynamic load rating of 3510 lbf and a static load rating of 2250 lbf, this bearing is designed to handle demanding combined radial and axial loads.
Precision Manufacturing: Conforming to P6 (ABEC-3) tolerance class, it guarantees minimal runout and vibration, which is essential for high-precision applications.
