Alternative principle and methods of rolling bearings
Most favorable price : sales@hellerbearings.com
A bearing alternative principles include the following:
The bearing capacity factor and allows the static load and other technical parameters as far as possible equal to the technical parameters of the first wife bearing;
Should choose to allow the speed limit is equal to or higher than the actual speed of the first wife bearing;
Alternative bearing accuracy class not be lower than the first wife bearing accuracy class; to be the same size, can not replace the bearings free to change to match the size of machine and bearing;
Bearing set methodology, to ensure the concentricity of the external cylindrical surface of the insert sleeve, and should be the correct choice of tolerance and cooperation.
Second, the rolling bearing of the method
The rolling bearing of the alternative methods include direct alternative and back pad alternative two, which also includes to narrow wide-generation, and change the size of the shaft or shell holes
Directly alternative. Alternative bearing inside diameter, outside diameter and thickness dimensions and wife bearing exactly the same, without taking any measures you can install and use.
Padded alternative. Padded can be used to substitute the alternative bearing diameter, diameter, and his first wife bearing exactly the same, only the width of the narrow. Washer thickness equal to the first wife wife bearings and alternative bearing width. The gasket inside diameter clearance fit with the shaft outside diameter of the outer diameter of the bearing inner ring. Washers at both ends of the surface to be parallel to the installation should be close to the axis washers shoulder.
Narrow wide behalf of the. When no alternative similar to the first wife bearing size bearing can be taken way to change the journal or shell hole to make it compatible with the alternative bearings. Journal or aperture processing can not be too large so as not to affect part strength. Machines of standard types of bearings, and try not to use this method.
Change the the size of the axis or shell Kong of the. Can be taken out for non-standard bearing, the way to change the journal or shell hole to make it compatible with the alternative bearing. Journal or aperture processing can not be too large so as not to affect part strength. Machines of standard types of bearings, and try not to use this method.
