Inch Tapered Roller Bearing

Inch tapered roller bearing comes from the British and American country. Its dimensions are measured in inches. Its structure, assembly size precision and rotating precision are different from the metric bearing. The product is mainly used for the imports of machinery or industry with special needs. Its structure type consists of single row, double row and four row tapered roller bearing.

Radial clearance and axial clearance of inch tapered roller bearing can be adjusted in the process of installation and can also be applied to the installation with axial pre-load. The size of axial clearance can greatly influence the work. If the axial clearance is too small, the temperature rises while it is too large, the bearing is easily damaged. Therefore, we should pay special attention to the adjustment of axial clearance of bearing in the installation and operation process.

Dimensions of inch tapered roller bearing are represented by converting inches to millimetres. The inner ring and outer ring of our products have product code respectively, which represents the inner and outer components. The product code is the combination of inner model and outer model. For instance, in the 17887/17831, 17887 is the inner model while 17831 is the outer model. Sometimes it can be simplified as 17887/31 at home.
