NSK bearing cage effect and structural characteristics

 May be a lot of customers using NSK Bearings when there are cases where doubt speed bearings slewing bearing system requires precision dynamic balancing, why have some tapered bearing bearing cage while others did not cage it.
     NSK Bearings (especially bearing) is divided with cage and without cage two kinds of structures. Which generally require large NSK Bearings withstand a greater load, often without cage, but in the inner and outer raceway filled with rolling elements. The majority are small and medium sized bearings with a cage.
     In NSK Bearings in the machining process, the configuration of the bearing rigidity of the bearing also a great influence NSK bearing outer ring, inner ring, rolling elements and cage is mounted to one of how. Simply put, that is first put NSK bearing inner and outer rings and then put aside to put the rolling element (on the side) and then adjust the position of the rolling element and finally put the cage.
     Now we all know, in the processing of NSK Bearings is also involved in the cage, then the cage NSK bearings mainly in the end is to play what role?
The role of the cage is:
     1, single row radial ball bearings and cylindrical roller bearings have powered machine bearing varieties used to guide and promote low-noise rolling in the right raceway;
     2, the rolling element cage equally spaced, uniformly distributed on the circumference in the raceway was working to prevent collision between the rolling elements and friction;
     3, in the separated type bearings, the rolling elements and a ring together, in order to prevent rolling off.
