Taper roller bearings are for industrial use and auto parts.The taper roller angles allow the bearing to handle a combination of radial and thrust loads.The steeper he cup angle,the greater the ability of bearing to handle thrust loads
The outer ring (or inner ring) of the double row tapered roller bearing is a unitary body. The inner rings of the two inner rings (or outer rings) are similar, and the spacers are arranged in the middle. The clearance is adjusted by the thickness of the spacers. The thickness of the spacers can also be used to adjust the pre-interference of the double-row tapered roller bearings.
