Fixing method of combined bearings
Thread Content
Currently, a high-speed rotor (with a speed of 3000 rpm and a length of 500 mm) is fixed at both ends using sealed double-row ball bearings. How should the fixing method at these two ends be designed? What are the guidelines for fixing the inner and outer rings? Is it related to the type of bearing?

Is there any axial force?» A conventional and viable design is as follows: at one end (the free end), a double-row self-aligning ball bearing is used for alignment and support; at the other end (the fixed end), a double-row angular contact bearing is used for positioning and support. The axial position on the free side is not fixed, while the bearing caps on the fixed side are pressed against the outer ring of the bearings. This approach is not entirely dependent on the type of bearing used~~~~
