Servicio personalizado

Las razones para elegir una solución de rodamientos adaptada son diferentes; las posibilidades son múltiples. A menudo se utiliza una solución complicada y costosa basada en rodamientos estándar porque se supone que de todos modos no está disponible una solución especial o que sólo puede implementarse a un costo elevado. De hecho, hay muchos casos en los que ocurre exactamente lo contrario. En la práctica, existen básicamente cuatro enfoques principales cuyos costos de desarrollo varían mucho.

1. Rodamientos en Dimensiones Especiales

La razón más común y sencilla para una solución de rodamiento personalizada es ajustar las dimensiones principales del rodamiento. Después de una reparación de una máquina, por ejemplo, es necesario repasar los asientos de la carcasa. En este caso, la solución más sencilla y rentable suele ser mantener las características del rodamiento estándar y fabricarlo en las nuevas dimensiones principales adecuadas.



2. Soluciones de rodamientos modificados

A continuing trend in the development of new machines is the desire for more performance. If you then reach the limits of individual components, you have to re-dimension them. However, building larger is inevitably associated with higher costs. If the problem concerns the bearing arrangement and the bearings used so far become too small, the cost increase is particularly high. In addition to the bearings themselves, the housing, the shaft and many conversion parts often become larger and more expensive. Downsizing, currently on everyone's lips, is the solution here. Depending on the bearing type and size, the internal geometry can be adapted, or a special cage can be used to optimise the number and dimensions of the rolling elements. An increase in load capacity of 10 %, for example, achieved in this way will approximately extend the service life by 40 %!


3. Integrated Bearing Solutions

Often the designer does not dare to approach integrated solutions apart from large automotive series. It is assumed that in small series this is expensive or too complicated anyway; the idea of feasibility is simply missing. Rolling bearing rebuilds are often very precise. In addition, sensors, hydraulics and lubrication form important interfaces between bearings and attachments. Among other things, KRW is a development partner for companies in the machine tool industry and offers ready-to-install system solutions with significantly reduced assembly costs for the customer. Important conversion and attachment parts as well as measurement technology and sensor technology are already integrated in the bearing. Most of the time-consuming bearing assembly and especially the error-prone bearing adjustment are thus eliminated.


4. Customised Bearing Solutions

Bearings with the highest degree of individualization are particularly suitable for products manufactured in at least small series and whose best bearing solution in terms of design does not correspond to a standard solution. In exceptions, the requirements or the necessary dimensions of a bearing are so far from standard solutions that an individual solution can also be considered for one-off productions or is even the only sensible alternative. The challenges faced by our engineers are as varied as the problems faced by our customers. In cases of doubt, we simply redefine the limits of what is feasible.
