NTN bearings to maintain the function and structure of frame
Most favorable price : sales@hellerbearings.com
NTN bearings are caged and not caged two structures. The NTN bearing large are generally required to bear large loads, often without a cage, but in the inner and outer raceway filled with rolling. And most small rolling of NTN bearing is a cage.
NTN bearing in the process, effect of NTN bearing configuration on NTN bearing rigidity is big NTN bearing outer ring, inner ring, rolling body and a holding frame is loaded onto a piece of. In simple terms, is the first NTN bearing inner and outer ring placed aside, inner ring, rolling body (and put aside), and then adjust the scroll position and, finally, put the cage.
Now we all know, in the process of NTN bearing is holder participation, then NTN bearing cage is exactly what role?
The cage effect:
1, single row radial ball bearing NTN and short cylindrical roller bearing NTN low noise varieties for NTN bearing motor using the guide and drive the rolling body raceway rolling in the right;
2, the holder of the rolling body, distance apart, are evenly distributed in the raceway to circle in order to prevent the work roller mutual collision and friction;
3, in the separation of NTN bearing, the rolling body and a ring together, in order to prevent the rolling body falling.
NTN bearing called the window, to isolate and guiding the rolling, low speed when the ball in a NTN bearing the situation and theoretical calculation of vibration value is basically the same pocket clearance of the cage in the radial and axial has a certain amount of activity, the total amount of activity is called radial retainer gap. The holder has a variety of structure type, complex shape in roller. Keep the pocket many distance of the frame, pocket hole shape of spherical, oval, round, rectangular and tooth type, its size is larger than the size of scroll, to pocket the difference between the gap, sometimes on the rolling remain connected part of the frame window is called between the lintel, connections and increased its frame strength effect of.

Many customers in the use of NTN bearing sometimes doubt high-speed NTN bearing such requirements NTN bearing the rotary system through the dynamic balance precision, why some NTN bearings with cages and some NTN bearings without cages. Today and share about NTN in bearing function and structure frame.NTN bearings are caged and not caged two structures. The NTN bearing large are generally required to bear large loads, often without a cage, but in the inner and outer raceway filled with rolling. And most small rolling of NTN bearing is a cage.
