7315B 75*160*37mm Single Row Angular Contact Ball Bearing
The 7315B bearing,with a bore diameter of 75 mm, outside diameter 160 mm, and
width of 37 mm.This single row angular contact ball bearing can
support both radial and axial loads simultaneously, with the axial
load being accommodated in one direction only. Depending on the
specific model, this bearing is capable of operating at high speeds
or even extremely high speeds. Compared to deep groove ball
bearings, it can withstand significantly greater unidirectional
axial forces.It is particularly well-suited for situations needing robust handling
of both radial and significant unidirectional axial loads at high
speeds.
