KOYO 28985/21 Bearing Detail

1.Inch series Taper Roller Bearing :

The structure and assembly dimensional accuracy and rotation accuracy of British conical roller bearings are different from those of metric bearings. It is mostly used in imported machinery or industries with special needs.British conical roller bearing refers to the conical roller bearing whose overall dimensions are measured by inch.

2.The role of single row tapered roller bearings:

  The single conical roller bearing has an outer ring, and its inner ring and a group of conical rollers are wrapped into an inner ring assembly by a basket-shaped cage. The outer ring can be separated from the inner ring assembly, according to the provisions of the ISO standard for the overall dimension of conical roller bearings, the outer ring or inner ring assembly of any standard type of conical roller bearing should be able to achieve international exchange with the outer ring or inner ring assembly of the same type. That is to say, except for the external dimension and tolerance of the same type of outer ring, the cone angle of the inner ring assembly and the diameter of the cone of the assembly must also conform to the relevant regulations of interchange.

3.Characteristics of single row tapered roller bearings :

  The conical angle of the outer ring raceway of the single row conical roller bearing is 10 ° ~ Before 19 °, it can bear the combined action of bearing load and radial load at the same time. The larger the cone angle, the greater the ability to bear axial load. Bearing with large cone angle, rear code plus B, cone angle is 25 ° ~ Between 29 °, it can bear larger axial load. In addition, the size of the clearance can be adjusted during the installation of the single row conical roller bearing.
