7217 BEP Bearing Product Overview & Core Advantages
The 7217 BEP is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. This metric bearing features a 40° contact angle, enabling it to effectively support significant axial loads in one direction alongside radial loads. Manufactured to a P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. Its optimized internal geometry and high-quality materials make it an ideal choice for high-speed operation and demanding industrial environments.
7217 BEP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7217 | Basic bearing designation indicating a metric angular contact ball bearing with an 85 mm bore and 150 mm outside diameter. |
| BE | Designates an optimized internal design with a 40° contact angle and enhanced internal geometry for superior performance. |
| P | Indicates the bearing is supplied with a glass fiber reinforced nylon cage (Polyamide cage), which is lightweight and ideal for high-speed applications. |
7217 BEP Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The 40° contact angle and robust single row design provide excellent resistance to combined radial and one-direction axial loads, ensuring high system rigidity and stability.
- High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, while the precision-ground chrome steel components and optimized raceway geometry contribute to a high limiting speed of 5,000 rpm.
- Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3), this bearing guarantees precise shaft running and minimal vibration, which is critical for precision machinery.
- Optimized Internal Geometry: Features like the calculated shoulder diameters (126.7 mm outer, 110.1 mm inner large-side) ensure proper load distribution and secure seating, maximizing bearing service life.
