Detailed Product Description
High Speed GCr15SiMn NTN Bearing 51000 Series With Low Friction Coefficient
Introduction
Thrust roller bearing support combined load consist of radial load and axial load (radial load shouldn't be bigger than 55% of axial load).Compared with other roller bearing , Thrust roller bearing is with lower friction coefficient, high speed and self-aligning properties.Thrust roller bearings is mainly used for heavy-duty machine tools, high-power marine gear boxes, oil rig, electrical and other machinery in the vertical.
