In 2014 these standards were aligned with general ISO GPS (Geometrical Product Specification) standards such as ISO 1101 and Imation on ISO 492 and ISO 199, and the changes that have been made to their previous editions, on the SKF e learning platform.
Single bearings and matched bearing pairs arranged in tandem Normal Check availability of C2, C3, C4, C5, reduced ranges of stValues are valid for unmounted bearings under zero measuring load. Matched bearing pairs arranged back to back or face to face
In order to facilitate this approach, this part of ISO 1940 takes the bearing planes A and B as reference planes for balance tolerances (tolerance planes). 4.5 4.5.1 Correction planes General Rotors out of balance tolerance need correction.
ISO 281:2007 specifies methods of calculating the basic dynamic load rating of rolling bearings within the size ranges shown irdance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces.
