KOYO bearings to determine the amount of interference

The bearings are typical surface working parts, the KOYO bearing surface minor wear, fatigue, corrosion failure, you can make the entire bearing failure, surface engineering technology to improve the state of the bearing surface, to improve the life of the bearing. Surface engineering technology after surface preparation, anti-fatigue, anti-oxidation, anti-radiation performance; improve the heat transfer surface or insulation; improve the surface of the conductive or insulating; improve the surface the guide magnetic or electromagnetic shielding; improve the surface of Graces, reflective or absorbing; improve the surface tackiness or non-tackiness; improve the surface suction or dry friction; improve the coefficient of friction of the surface (increase or decrease); improved surface decorative or an antique do the old. Surface engineering technology design: the structural design of the surface layer; surface layer material design; process design of the surface layer; surface engineering workshop design and surface engineering vehicles; economic analysis of surface engineering technology.
Installation of tapered bore bearings always interference fit. Decrease the value of the radial internal clearance or the axial displacement of the inner ring in its conical journal is used to determine and measure the amount of interference. Measured with a feeler gauge before and after the clearance reduction: KOYO bearing installation, measured with a feeler gauge radial internal clearance method is suitable for large and medium-sized spherical bearings. It is better to measure the clearance between the rollers outer ring and no load.
Measure the axial advance distance: Install tapered bore bearings, advance distance by measuring the inner ring on the journal. The axial promote the guiding values of the distance. However, the method is more suitable for this case the propulsion method. This installation method provides a reliable method of determining the amount of interference and easy way. KOYO bearings by controlling axial displacement with respect to a predetermined position, to achieve a correct fit. The method uses the hydraulic nut with a dial gauge, and installed in the selected pump via specially calibrated digital measurement. The necessary pressure and the axial displacement of a single bearing, these values can be determined the precise positioning of the bearing.
