Inch taper bearings are bearings designed so that the cone tip formed by the rolling groove of the inner ring, the outer ring and the cone ball profile all converge at one point on the bearing shaft. Due to this inclination, when there is radial load, a force component is directed along the shaft of rotation (load reduction). Therefore, the use of two bearings facing each other or arranged in different ways is essential for balance and tends to cancel this axial force.
Depending on the angle - large or normal contact, bevel or normal tapered bearings are available. And according to ISO or GOST standards, there are also metric tapered or inch tapered bearings of different sizes.
