7317 BEGAP Bearing Product Overview & Core Advantages
The 7317 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. Its design is optimized to support significant axial loads in one direction alongside radial loads, making it ideal for arrangements where precise shaft positioning and high rigidity are critical. Manufactured to P6 (ABEC-3) tolerance with a 40° contact angle, this bearing delivers reliable operation in demanding environments. The use of a nylon cage contributes to smooth, high-speed operation, while its lubricated and open construction allows for customized lubrication regimes tailored to specific application needs.
7317 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7317 | Standard bearing series designation indicating a metric single row angular contact bearing with an 85 mm bore, 180 mm OD, and 41 mm width. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| GA | Indicates a nylon cage (glass fiber reinforced polyamide), which is lightweight and promotes quiet, high-speed operation. |
| P | Specifies a P6 tolerance class (equivalent to ABEC-3), ensuring high dimensional accuracy and running precision. |
7317 BEGAP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a steep 40° contact angle provides excellent resistance to axial loads from one direction and combined (radial and axial) loads, ensuring stable operation and long service life.
- Optimized for High Speeds: The lightweight nylon cage reduces centrifugal forces, enabling a high limiting speed of 4,800 rpm and smooth rotation with minimal friction and heat generation.
- Precision Engineering: Manufactured to P6 tolerance, this bearing guarantees precise internal clearances and geometry, which is crucial for applications requiring high running accuracy and minimal vibration.
- Robust Material Construction: Made from chrome steel for both rings and balls, the bearing offers high strength, durability, and resistance to wear, suitable for a wide temperature range from -30°C to 110°C.
- Flexible Lubrication: The open seal type allows for the use of specialized lubricants, enabling optimal performance customization for specific operational conditions.
