There are two kinds of thrust roller bearings,which include cylindrical roller thrust bearings and tapered roller thrust bearings.Thrust roller bearings can merely hold axial loads.
      Cylindrical roller thrust bearings are suitable for arrangements that have to support heavy axial loads,which are produced in single row and double row designs.The components of this bearing  are cylindrical roller and cage,shaft washers and housing washers.
      Tapered roller thrust bearings also have two types--single direction tapered roller thrust bearings and double direction tapered roller thrust bearings.The design with cage can make it separately and easily for components to be mounted.
