7216 BEGAP Bearing Product Overview & Core Advantages
The 7216 BEGAP is a precision angular contact ball bearing designed for applications requiring high rotational accuracy and robust performance. Engineered with a 40° contact angle, it excels at handling combined loads—simultaneously supporting significant radial forces and unidirectional axial thrust. Manufactured to P6 (ABEC-3) tolerance class, it ensures minimal runout and smooth operation, making it ideal for high-speed spindles and precision machinery. Its open design, combined with a lightweight nylon cage, facilitates optimal lubrication flow and contributes to its high limiting speed of 5,300 rpm.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7216 | Basic bearing designation: 80 mm bore, 140 mm OD, 26 mm width. |
| BE | High contact angle design (40°), optimized for high axial load capacity. |
| GA | Lightweight, glass-fiber reinforced nylon cage (Polyamide 66). Enables smooth operation at high speeds. |
| P | Precision tolerance class P6 (equivalent to ABEC-3). |
7216 BEGAP 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 handle high axial loads in one direction, in addition to substantial radial loads. The optimized internal geometry ensures stable operation under combined loading conditions.
- Superior High-Speed Performance: The nylon cage (GA) reduces centrifugal forces, lowers friction, and allows for efficient lubricant distribution, directly contributing to the high limiting speed of 5,300 rpm.
- Precision Engineering: Manufactured to P6 tolerance with strict dimensional control on bore, outside diameter, and width. This guarantees precise shaft and housing fits, reduced vibration, and enhanced operational accuracy.
- Optimized Material Selection: Constructed from high-grade chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long service life under demanding conditions.
7216 BEGAP Bearing Typical Application Areas
The 7216 BEGAP is ideally suited for high-performance applications where speed, precision, and reliability are critical. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes: Industrial robotics and automation systems.
- Pumps and Compressors: For handling axial and radial loads in fluid movement systems.
- Electric Motors: High-frequency spindles and servo motors.
