WST spherical roller bearing E type design consist of symmetrical rollers, floating guide ring through the double row roller, inner ring without rib,two sheet steel cages. The dynamic load rating average prolonged 25%~30%. So at the same condition, the rating life of E type bearing is 2.0~3.5 times than standard design.
E type is enhanced design, with large size and more quantity rollers. So compared with standard design bearing they have a long service time and heavy loading.
We have advanced equipment import from Germany, Especially Heat treat equipment is AICHELIN import from Austria.
We use the top brand bearing steel , Just like Xingcheng ,Baosteel ,HBIS make sure the quality from the material.
