Currently the main use of the deep groove radial ball bearings and tapered roller bearings.
Deep groove radial ball bearings features are: ① can be made large clearance , allows a greater misalignment and shaft machining bending deformation ; ② running resistance slightly tapered roller bearings ; ③ low price. Deep groove radial ball bearings The main disadvantage are: ① poor impact resistance ; ② can not bear large axial force ; ③ poor corrosion resistance ; ④ life below the tapered roller bearings , ⑤ under the same carrying capacity size than large tapered roller bearings . Tapered roller bearing characteristics are: ① with a larger radial and axial load carrying capacity ; ② in the same carrying capacity and life circumstances, smaller than ball bearings ; ③ good regulating performance , whether it is the axial clearance or pre- plus load , can according to the design requirements to achieve its optimum performance ; ④ because separable inner and outer raceway , installation and removal is very convenient ; ⑤ with deep groove radial ball bearings compared to the same loads and life conditions, lower prices ; ⑥ self sewage capacity , as tapered roller bearings inherent characteristics of the automatic shift from oil raceway contact area to remove any particulate contaminants , thus greatly reducing the extent of contamination by the work environment ; ⑦ has a strong impact resistance. Tapered Roller Bearings shortcomings are: ① processing, assembling high precision machining and assembly ( including the axial deformation under load ) greater impact on bearing life ; ② running resistance slightly higher than deep groove radial ball bearings. Tapered roller bearings and deep groove ball bearings to which is better depends on the specific circumstances, the current domestic multi- groove radial ball bearings, Both bearings are used abroad . | |||
