SKF bearing before and after installing, measuring the radial internal clearance with a feeler gauge method is suitable for large and medium sized spherical and bearings. The best is to measure the clearance between the outer rings and rollers without.
Measuring the lock nut tightening angle is a proven and effective method used to determine small tapered neck bearing the correct degree of interference. The tightening angle a guideline has been established, providing accurate positioning of the bearing on a tapered shaft seating.
Method is more suitable for this situation, "SKF propulsion methods". This method provides a reliable and easy way to determine interference. By controlling the NSK bearing axial displacement relative to the intended location, you can achieve the correct fit. The method used with dial gauge hydraulic nuts, and install on the selected pump specially calibrated digital measurement. Required oil pressure and axial displacement of the bearing, which determines values for precise positioning of the bearing by measuring the inner ring expansion, simple and large, spherical and very precisely determined bearing in the correct location on the shaft.
Installed in place of the inner ring shaft mount the outer ring of the bearing box, care must be taken to see if the inner and outer rings properly, to avoid scratching the FAG bearing raceways and rolling elements. If cylindrical and needle roller bearings without flanges flanges rings or when the side flange side of the inner ring, we recommend using the installation sleeve. Sleeve outer diameter should be equal to the inner ring raceway diameter f, machining tolerance standards should be a D10.
