7219 BEGAPH Bearing Product Overview & Core Advantages
The 7219 BEGAPH is a single row angular contact ball bearing engineered for applications requiring high precision and the ability to accommodate combined loads. Featuring a 40° contact angle and manufactured to P6 (ABEC-3) tolerance class, this bearing is optimized to handle significant axial loads in one direction simultaneously with radial loads. Its robust construction from chrome steel and nylon cage ensures reliable performance in demanding environments, making it an ideal choice for high-rigidity and high-speed applications.
7219 BEGAPH Bearing Model Code Explained, Specifications & Naming Convention
The model number 7219 BEGAPH provides specific technical information:
- 7219: Basic designation indicating a metric, single row angular contact ball bearing with a 95mm bore and 170mm outside diameter.
- BE: Signifies an optimized internal design with a 40° contact angle and enhanced internal geometry for superior performance.
- GA: Indicates the use of a glass fiber reinforced nylon cage, which contributes to lower friction, quieter operation, and is suitable for high-speed applications.
- PH: Denotes that the bearing is pre-lubricated with a high-performance grease, offering immediate readiness for use and extended service life.
7219 BEGAPH Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle provides excellent rigidity and is specifically engineered to support high combined radial and axial loads in one direction. The calculated dynamic load rating of 29,025 lbf and static load rating of 26,550 lbf confirm its robust performance.
- High-Speed Performance: The lightweight nylon cage (GA) minimizes centrifugal forces, enabling a high limiting speed of 4,800 rpm. This makes the bearing suitable for applications requiring rapid rotation.
- Precision Operation: Manufactured to a P6 tolerance class, this bearing ensures precise running accuracy and minimal vibration, which is critical for high-precision machinery.
- Ready-to-Use & Long-Lasting: The bearing arrives pre-lubricated (PH), facilitating easy installation and providing reliable operation from the start within its specified temperature range of -30°C to 110°C.
7219 BEGAPH Bearing Typical Application Areas
The 7219 BEGAPH is ideally suited for a wide range of demanding industrial applications, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Equipment
