The tapered roller bearings can be used to carry radial -axial combined loads.At the same time in carrying radial loads,additional axial thrust will be implicated.The tapered roller bearings are separable bearings.The tapered roller bearings can be divided into three categories:singe row,double rows and four rows. We can produce: Singr row:Type 30000; Double rows:Type 350000,Type 370000,Type 350000D1,Type 350000D; Four rows:Type 380000; The same type of inch tapered bearing.
