Analyzing the Technical Specifications of 6912 ZZ Bearings
Material and Construction
6912 ZZ bearings are made of high-quality materials. The rings and balls are typically made of chrome steel. This material offers excellent hardness and wear resistance. It ensures the bearing can withstand heavy loads and high speeds.
The construction of these bearings is precise and robust. They feature a deep groove design, which allows for high radial load capacity. The balls are held in place by a cage, usually made of polyamide or brass.
The “ZZ” in the name indicates metal shields on both sides. These shields are typically made of steel. They prevent contaminants from entering the bearing while allowing smooth rotation. This design helps maintain the lubricant inside, extending the bearing’s life.
Size and Dimensions
The size and dimensions of 6912 ZZ bearings are standardized. This makes them easy to replace and integrate into various machines. Here are the key measurements:
- Inner diameter: 60 mm
- Outer diameter: 85 mm
- Width: 13 mm
These dimensions make 6912 ZZ bearings suitable for many applications. They can fit in spaces where larger bearings might not. Yet, they are robust enough to handle significant loads.
The precision of these dimensions is crucial. It ensures proper fit and alignment in machinery. Even small deviations could lead to inefficiency or premature wear. That’s why 6912 ZZ bearings are manufactured to tight tolerances.
Load Ratings and Performance Standards
6912 ZZ bearings are designed to handle both radial and axial loads. Their load ratings are a key factor in their performance. Here are some typical ratings:
- Dynamic load rating: Around 22.5 kN
- Static load rating: Approximately 15.3 kN
These ratings indicate the bearing’s capacity to handle forces during operation and at rest. The dynamic rating is especially important. It shows how much load the bearing can handle while rotating.
Performance standards for 6912 ZZ bearings are high. They can operate at speeds up to 7,500 RPM, depending on the application. This makes them suitable for a wide range of machinery.
Temperature tolerance is another important factor. These bearings can typically operate between -20°C and 120°C. This wide range makes them versatile for various environments.
