In industrial machinery, self-aligning ball bearings are one of the common bearing types. They have an automatic self-aligning function with a double-row ball bearing. In terms of structure, self-aligning ball bearings can be divided into cylindrical bore self-aligning ball bearings and tapered bore self-aligning ball bearings. In structure, installation method, application scenarios, performance characteristics, etc. aspects, these two types of self-aligning ball bearings have some differences.
To ensure the bearings operate efficiently and reliably, understanding these differences will help engineers choose the appropriate bearing type in different mechanical equipment.
As its name, the cylindrical bore self-aligning bearing's inner ring bore is cylindrical.
For cylindrical bore self-aligning bearing, the shaft can be directly inserted into the bearing bore, and during the installation process, there is no additional fixing device required. So it is convenient and easy to install.
The cylindrical bore self-aligning ball bearing' design structure determines that the fit between the bearing and the shaft usually adopts a transition fit or a tight fit. However, since its structural characteristics, the bearing's fit between the shaft and the inner ring limits the bearing's adjustment ability. If the axial position needs to be precisely adjusted, auxiliary devices such as washers must be used, which to a certain extent limits its application range.
In small axial loads and low requirements for axial position accuracy, cylindrical bore self-aligning ball bearings are a great choice. Small motors, pumps, fans, etc. applications usually do not require frequent axial position adjustments. The obvious advantage of cylindrical bore self-aligning ball bearings is simple installation and replacement.
In addition, due to its relatively simple structure and relatively low manufacturing cost, it is more economical and practical in general industrial applications.
Cylindrical bore self-aligning ball bearings have a better advantage in equipment that requires frequent replacement. As mentioned above, cylindrical bore self-aligning ball bearings have a simple installation structure and a lack of complex tools when replaced. However, their adjustment capabilities are limited, when the bearings are worn or loose, to maintain the machines normally operating, there may be a more frequent replacement.
The tapered bore self-aligning ball bearing' inner ring bore is tapered, usually, the taper is 1:12 or 1:30.
For tapered bore self-aligning bearings, the bearing's inner ring slides axially on the shaft, thereby through adjusting the position of the locking nut or adapter sleeve, the tapered bore self-aligning ball bearings can achieve more precise axial positioning.
This tapered bore design can withstand greater loads and achieve a very high interference fit during installation for bearings, greatly improving the stability and service life of the bearing.
This type of bearing has significant advantages in equipment that requires frequent adjustments and high precision requirements due to the position can be controlled by a simple adjustment tool.
The tapered bore design provides higher installation accuracy and stability for bearings, so tapered bore self-aligning ball bearings play an irreplaceable role in large machine tools, heavy machinery, mining equipment, etc. These occasions need to withstand large loads, have high axial position accuracy requirements, and sometimes require precise adjustment of the bearings' axial position.
Tapered bore self-aligning ball bearings require special tools for adjustment during installation and replacement.
When the bearing begins to wear or loosen, people can adjust the locking device to re-tightened, thereby extending its service life. For large equipment, this has great significance for their maintenance.
