Japanese NTN bearings company empolder turning resistance reduced transmission by using airtight deep groove ball bearing, which improve the form of airtight’s material and airtight lip, optimize the airtight’s slippage of inner ring, to make the light touched sealed lip fray as soon as possible, and form untouched airtight, in order to achieve the smallest clearance.

 

Compare with the departed light touched sealed ball bearings, control the diameter of intrusive curiosity 35% than before, and the oil transporting is 30 time than before, which make sure the lubrication of bearing, and the turning resistance reduces 80% than before. In addition, it also improves the figure of maintainer’s pocket, adjusts the character of lubricant. In the condition of intrusive curiosity lubricating, the life is longer than other products.
