50Mn Steel
Other suppliers use 42-gauge steel. 50 manganese steel has very good wear resistance and is mostly used in mountain quarrying equipment, for example, the breaking hammer is made of manganese steel. In addition, our slewing bearing adopts the technology of multiple quenching to make it soft inside and rigid outside. It is not easy to break, the interior is flexible, and the surface is particularly hard. No. 42 steel slewing bearing made by others has poor wear resistance. Once mishandled, the slewing bearing is easily broken and very difficult to repair. Our slewing bearing is $180 more expensive than theirs’
