  • Bearing housing and rolling bearing device
    Patent number: 10550888
    Abstract: A bearing housing in which a rolling bearing is built includes a cylindrical inner circumferential surface and an end face formed continuously with an axial end of the inner circumferential surface in an orientation perpendicular to a central axis of the inner circumferential surface. The inner circumferential surface has an annular groove that is radially outwardly recessed around an entire circumference of the inner circumferential surface. A snap ring is attached into the annular groove to reduce displacement of the rolling bearing. A recess recessed in an axial direction and extending in a radial direction is provided in the end face of the bearing housing.
    Type: Grant
