Mine Drilling Tool Bearing for Mining Machinery

Mine drilling tool bearings are important components of mining machinery, mine drilling tool bearings could be divided into main thrust ball bearings, angular-contact ball bearing and so on. And the angular-contact ball bearings are used for drilling platform and switched reluction motor.Yusion supplies S-2 Rock Bit balls apply for angular-contact ball bearings for mining machinery. The ball surface has a smooth ground and polished finish.They provide good wear characteristic and good services for severe shock loads.
