7217 BEGAP Bearing Product Overview & Core Advantages
The 7217 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined radial and axial loads. Featuring a 40° contact angle and manufactured to P6 (ABEC-3) tolerance class, this bearing delivers superior rotational accuracy and rigidity. Its optimized internal geometry and nylon cage contribute to smooth, high-speed operation, making it an ideal solution for demanding industrial environments where reliability and precision are paramount.
7217 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
- 7217: Basic bearing designation (85mm bore, 150mm OD, 28mm width)
- B: 40° contact angle
- E: Optimized internal design
- GA: Light preload
- P: P6 tolerance class (ABEC-3 precision)
7217 BEGAP Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with a 40° contact angle provides excellent resistance to combined loads, effectively handling both radial forces and substantial axial loads in one direction. The precisely calculated shoulder diameters ensure optimal load distribution.
High-Speed Performance: The lightweight nylon cage reduces centrifugal forces and maintains stability at limiting speeds up to 5,000 rpm, while the optimized internal geometry minimizes friction and heat generation.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional tolerances (bore/OD: -0.015mm to 0), this bearing ensures precise shaft positioning and minimal runout for critical applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and long service life under demanding operating conditions.
7217 BEGAP Bearing Typical Application Areas
The 7217 BEGAP angular contact ball bearing is ideally suited for:
- Machine tool spindles and high-precision machining centers
- Industrial pumps and compressor systems
- Precision gearboxes and transmission systems
- Robotic arms and automation equipment
