6815 Bearing Product Overview & Core Advantages
The 6815 metric ball bearing is a single row deep groove ball bearing engineered for reliable performance in radial load applications. Characterized by its open design and ABEC-1 precision class, this bearing offers a robust solution for general industrial use. Its compact cross-section, with a 75 mm bore and 95 mm outside diameter, provides an excellent balance of load capacity and space efficiency. Manufactured from chrome steel with a stainless steel cage, it ensures durability and consistent operation.
6815 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 68 | Series designation indicating a deep groove ball bearing with a specific dimensional series. |
| 15 | Bore diameter code, corresponding to a 75 mm bore diameter. |
| Open | No seals or shields, allowing for higher limiting speeds and easy re-lubrication. |
| C0 | Standard radial internal clearance group (0.01mm to 0.03mm). |
| ABEC-1 | Defines the tolerance class for precision, suitable for most industrial applications. |
6815 Bearing Structural Features & Performance Benefits
The performance of the 6815 bearing is derived from its fundamental deep groove ball bearing construction. The uninterrupted deep raceways on both rings enable it to handle not only significant radial loads (dynamic rating: 2768 lbf, static rating: 2880 lbf) but also moderate axial loads in both directions. The use of a stainless steel cage provides high strength and corrosion resistance, contributing to stable operation at the specified limiting speed of 7,600 rpm. The open seal type minimizes friction, allowing for higher rotational speeds and facilitating maintenance and lubrication. The standard C0 radial clearance ensures reliable performance under normal operating conditions and temperatures ranging from -30°C to 110°C.
6815 Bearing Typical Application Areas
This versatile single row bearing is widely used across various sectors due to its balanced performance characteristics. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial load support
