Ball roller ,thrust bearings,load and its axial cord are formed a certain angle ,from one raceway pass away another.So,this kind of bearings are different from other thrust bearings.Ball roller thrust…
Needle roller bearing is roller bearing with cylindrical roller,compared with its diameter,the roller is slender and long.This roller is called needle roller.Althougn it has smaller cross section,the …
This type of bearing is separable .As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction,these bearings have very good capacity of radial load,su…
With the same center as the bearing,the spherically formed outer ring raceway can make self-alignment.Their rolling elements linearly come into contact with the raceways of inner ring and outer ring.T…
Tapered roller bearings are gene rally used to support combined load mainly consisting of radial load.Their cups are separable foreasy assembling.During mounting and using ,radial clearance and axial …
