KOYO combined bearing / needle roller / angular contact ball bearing NKIB5919

Product Description

KOYO combined bearing / needle roller / angular contact ball bearing NKIB5919

Needle Roller Bearing overview

 Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited. Because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings

 

 

Characteristics and use of combination bearing 

 

 

With the development of science and technology, in order to save materials and space, reduce the design, manufacturing, installation and commissioning of the workload, improve accuracy, reduce the cost, shorten the production cycle, bearing positive combination bearing (some fixed with bearing as a whole combination of bearings, such as combined needle roller and thrust roller bearing and bearing unit direction)
