Tapered roller bearings and needle roller bearings which is the difference between

Tapered roller bearings and needle roller bearings are more commonly used two kinds of bearings, but between the two, has a big difference.
Tapered roller bearings are precision bearings. Such bearing installation and removal more convenient; generally only used with the radial load carrying loaded guns, only the inner and outer rings are single row bearings with ribs steady with a smaller or larger intermittent axial load axial load; has high loads, background noise, and high speed characteristics.
Needle roller bearings, compact structure, small radial size, load capacity, withstand greater radial load. Using high-cage, can correctly guide roller parallel to the axis.
          Tapered roller bearings and needle roller bearings fundamental difference is: tapered roller bearings rolling body is tapered roller; needle roller bearings needle roller is rolling.
          Tapered roller in addition to radial force than can withstand axial force, and needle roller bearings can withstand radial forces;
          Tapered roller bearings are generally of high quality bearing steel and special steel; rather thin needle roller bearing is used in steel stamping.
          The company also supplies Class 7 bearings.Tapered roller bearings are widely used in mining, automobile, metallurgy, mill, plastic machinery and other industries.
Tapered roller backing bearings mainly bear radial diameter and axial joint load. Carrying capacity depends on the outer ring raceway angle, angle greater carrying capacity.
In tapered roller bearings, roller and inner and outer raceway surfaces are conical with, in the process, the roller diameter of the ferrule cone, the cone angle and length of the tapered surface binding may affect the size of the base surface distance
Tapered roller bearings have tapered inner and outer ring raceway, Tapered Roller arranged in between. Tapered roller bearings are generally separable, ie, with tapered conical inner components can be installed separately from the outer ring. According to the rolling element bearing rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be adjusted during installation the user; double row and four row tapered roller bearing clearance in the factory according to user requirements is given, not to be user adjusted.
The company also supplies Class 7 bearings.
