nn30k series-double row-cylindrical roller bearings

2020-7-142 Double row cylindrical roller bearings (NN type): In the application of machine tool spindle double-row precision cylindrical roller bearings are also used usually combined with precision angular contact ball bearings or thrust bearings This type bearings can Therefore cylindrical roller bearings are used in the medium large scale machine tool with large load high rigidity and low speed ZYS cylindrical roller bearings including twostructure series: single row cylindrical roller bearings N10 and double row cylindrical roller bearings NN30 The bearing bore also has two kinds: cylindrical bore and

Double Row Cylindrical Roller Bearings

Double Row Cylindrical Roller Bearings NN design have two rows of Cylindrical Rollers guided by three ribs on the inner ring The outer ring has no guide ribs making the outer ring separable This is why these bearings cannot carry axial loads Double Row Cylindrical Roller Bearings type NN30K

2019-7-222) As the roller linearly comes into contact with inner ring and outer ring with less coefficient of friction these bearings have very good capacity of radial load and are suitable for electric motors automobiles transmission shafts and gear shafts 3) Double-row cylindrical roller bearings are greatly used for the spindles of machine tools
