In order to be able to achieve on the axis (rotating State) passed load and the movement of qualified system relative to the housing (static system) location of basic tasks, NSK bearings has played a key role. Meet the NSK bearing's role is to make bearings respectively of the geostationary ring and rotating ring mount housings (stationary part) and axis (rotating part) in conjunction to keep abreast.
Both on the shaft and in the housing, NSK bearings are required in a radial, axial and tangential direction three direction fixed its position. Tangential and radial positioning is achieved through tight fit of the bearing rings, axial position only in a few cases, however tight fit; General axial limited parts, such as the end cap and retaining ring to limit the axial position in the context of clearance.
In cooperation with select NSK bearings you should emphasize the following four considerations:
1, NSK bearings fit to be able to make mounting and dismounting of bearings is simple and convenient, saves time as possible, the provincial, provincial spending points.
2, there is the ring in their mating surfaces cannot slide along tangential direction, so as not to damage the mating surfaces.
3, in order to reduce the degree of deformation of bearing rings, and be able to give full play to the carrying capacity of the bearing, bearing rings the best have good support and subject to uniform.
4, the need to adapt to the axial position, have the ability to walk within a certain range, so the free end bearing must be able to adapt to changes in the length of the shaft and housing bore.
