Are ball bearings suitable for applications where space is limited?

Ball bearings are suitable for applications with limited space. Ball bearings have the characteristics of small radial clearance, small axial width, and compact structure, which make them advantageous in applications with limited space.
Specifically, the radial clearance of ball bearings is small. For example, angular contact ball bearings can use preloading devices to reduce the radial clearance, thus having high operating accuracy. Meanwhile, the axial width of ball bearings is small, and some bearings can even withstand both radial and axial composite loads, making their structure more compact and combination simpler.
In addition, micro ball bearings have more applications in some precision fields due to their small size and light weight. For example, micro ball bearings are used in equipment such as vacuum cleaners, drones, and fresh air systems.
Therefore, ball bearings have great potential in applications with limited space and can effectively solve the problems caused by space limitations.
