Current location:
- Main bearings, also known as crankshaft bearings, are designed to support the crankshaft within the engine block. They are positioned at the main bearing journals of the crankshaft and provide support for the rotational motion of the crankshaft. Main bearings are subjected to radial loads and are crucial for maintaining the alignment and smooth rotation of the crankshaft.
When the bearing is subjected to loads, the balls move within the grooves, supporting the load and reducing friction. The deep grooves provide a larger contact area for the balls, enhancing the bearing's load-carrying capacity and stability. The miniature size of MDGBBs allows them to be used in confined spaces and provides a smooth and quiet operation. Brand reputation and warranty also play a role- Spherical Roller Bearings: Spherical roller bearings are designed to support heavy radial loads, as well as moderate axial loads, and are capable of accommodating misalignment. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.
In terms of installation, four-row tapered roller bearings typically require more attention than standard bearings due to their complexityFactors Affecting 6004 ZZ Bearing Price
