7217 BEGAF Bearing Product Overview & Core Advantages
The 7217 BEGAF is a precision angular contact ball bearing designed for demanding applications requiring high rotational accuracy and reliability. This single row bearing features a 40° contact angle, optimized to support significant combined loads—handling both radial forces and substantial axial loads in one direction. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running precision. Its open design, pre-lubricated for immediate use, and robust construction using chrome steel components make it an ideal solution for high-speed and high-rigidity applications.
7217 BEGAF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7217 | Basic bearing designation indicating a metric series with an 85 mm bore and 150 mm outside diameter. |
| BE | Designates a 40° contact angle and optimized internal geometry for high axial load capacity. |
| GA | Indicates a lightweight, high-strength stainless steel cage, suitable for high speeds and corrosive environments. |
| F | Signifies that the bearing is supplied pre-lubricated (lubricated), ready for immediate installation and operation. |
7217 BEGAF Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 40° contact angle and robust single-row design provide excellent rigidity, enabling the bearing to handle high combined radial and axial loads effectively. The calculated load points ensure stable performance under complex loading conditions.
- High-Speed Performance: The stainless steel cage (GA) offers low mass and high strength, contributing to lower centrifugal forces and enabling a high limiting speed of 5,000 rpm. This makes it suitable for demanding rotational applications.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance with tight dimensional controls on the bore, outside diameter, and width, ensuring smooth operation, reduced vibration, and precise shaft positioning.
- Durability and Compliance: Constructed from chrome steel for rings and balls, providing high fatigue life. The bearing is compliant with ROHS and REACH regulations, making it suitable for global markets.
