7210 BEGAP Bearing Product Overview & Core Advantages
The 7210 BEGAP is a single row angular contact ball bearing engineered for applications requiring high precision and the ability to accommodate combined loads. Its defining feature is the 40° contact angle, which provides excellent axial load capacity in one direction while also supporting significant radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures high running accuracy and is pre-lubricated for immediate use, making it an ideal solution for high-speed and high-reliability machinery.
7210 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7210 | Basic bearing designation indicating a metric series with a 50 mm bore and 90 mm outside diameter. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| GA | Indicates a light preload applied to the bearing, enhancing rigidity and minimizing axial play for precise operation. |
| P | Signifies the P6 tolerance class (equivalent to ABEC-3), ensuring high dimensional and running accuracy. |
7210 BEGAP Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a single row design with a 40° contact angle and a GA preload provides a very stiff bearing arrangement, crucial for applications where shaft deflection must be minimized.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads simultaneously, with the axial load capacity being particularly high in one direction due to the steep contact angle.
- Optimized High-Speed Performance: The lightweight Nylon cage reduces centrifugal forces, contributing to a high limiting speed of 9,000 rpm. The open design and pre-lubrication facilitate efficient heat dissipation.
- Material Integrity: Constructed from chrome steel for both rings and balls, offering high durability and resistance to wear under demanding operating conditions.
7210 BEGAP Bearing Typical Application Areas
This bearing's high-speed capability, precision, and axial load capacity make it suitable for a wide range of demanding applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Pumps and Compressors
- Precision Gearboxes
- Agricultural and Construction Machinery
