Design features of MRO-674GH slewing bearing
MRO-674GH slewing bearing with external gear is four point contact ball slewing ring bearing. It can take axial/radial loads at the same time, meanwhile provide stable and smooth rotation. Compared with crossed roller slew bearing of same size, MRO-674GH ball slewing ring has lower loading capacity and stiffness, but its rotation is more flexible, and suited for higher speed rotation too.
BRS can produce external slewing bearing like MRO-674GH with hardened gear teeth, which can improve bearings wear resistance and extend bearings service life.
Application of MRO-674GH slewing bearing
Cranes, excavators, forest machinery, loading machinery, etc.
