Another typical design

There is no full cage roller bearing design. Of course, from a lower speed spindle bearing point of view, full roller bearings caused by the decline in the ability of rotation of the bearing application not become an obstacle. However, the friction between the rolling elements can not be ignored is the key.
The reason for the bearing cage design, an important function is to separate two adjacent rolling elements in the bearing rolling elements run time to avoid Backing bearings the internal friction, reduce friction and noise. Therefore, although the full roller bearings with high load carrying capacity, but in the spindle bearings, due to rolling friction inside its still not the ideal choice.
Further, the above-mentioned another cage design, i.e. similar to the traditional one-piece bearing retainer. SKF Nautilus bearing the integral type cage is not selected, mainly because of its size is too large, its own weight will cause deformation of the cage, the rolling element and bring more friction between the cage. Furthermore, a device for generating the energy, wind turbine design is an important issue is to increase the energy density, to maximize the reduction of energy loss of its components. From this point of view, one-piece cage also has limitations..In addition to SKF Nautilus bearing cage design, the market there are several different cage designs. Respectively, are to compare the advantages and disadvantages of several cage.
