The final and binding selection of a largediameter antifriction bearing is principally made by us. Selection determines the correct dimensioning of bearing races, gearing and bolt connections. We, therefore require that you complete our 100 applications question aire to provide us with all necessary data to help in selection of the appropriate bearing.
            The most important data for choosing the right bearing are:
1. Applied loads
2. Collective loads with respective time percentages
3. Speed or number of movements and angle per time unit together with the relating collective loads
4. Circumferential forces to be transmitted by the gearing
5. Bearing diameter
6. Other operating conditions.
             Full completion of the  100 form will enable us to largely respect your requests and prepare a technically adequate and economical bearing proposal. Whenever possible, the completed 100 form should be submitted to us during the planning stage, but no later than the order placement to allow for confirmation of the bearing.
             Bearing selection by catalogue This catalogue permits you to make an approximate bearing selection to be used in your project work. The Rothe Erde bearings listed in this catalogue are allocated critical load curves for their static load capacity as well as service life curves. For defining the required bearing load capacity, the determined loads must be multiplied by the "load factors" indicated in Table 1 for the various application cases, except for types 13 and 21 of the  210 type series. If no applications are indicated, comparable factors have to be used, depending on the mode of operation.
