Taper Roller Bearing 31305

The double-row tapered roller bearing has various structures, including a double raceway outer ring and two inner rings, and a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer.
This type of bearing can bear both radial load and bidirectional axial load, and can limit axial displacement of the shaft and housing within the axial clearance range of the bearing.
