SKF gave major contribution to the development of the revised ISO 492 standard, which will enable customers to better integrate bearings into their machinery. ISO 492 incorporates GPS (Geometrical Product Specifications), enabling the tolerance of rolling bearings and the ISO GPS systems to be based on the same platform. A number of SKF experts have been involved in the review of ISO 492, which has resulted in the final draft of the standard. ISO 492 will give users more information about the interface between SKF products and the rest of their machinery in order to better integrate our products. Today you need to be an expert in bearings, to understand that for instance, the bearing diameter is given as an average, but with revised ISO 492 this dimension is clearly described by using the common industrial language of ISO GPS. It functionally takes the interface between the bearing and another mechanical part into account.
