Existen ocasiones en las que una aplicación requiere que un motor soporte una carga radial para la que los cojinetes de deslizamiento no son adecuados. En casos como bajas revoluciones, carcasas inusuales, etc., puede ser conveniente convertir el motor del cliente montado sobre cojinetes de deslizamiento envés de obtener un motor de repuesto con rodamientos de bolas / rodillos. Este artículo contiene procedimientos sugeridos y advertencias sobre problemas potenciales relacionados con dichas conversiones.

Primero, inspeccione las tapas del motor para asegurarse de que tengan la rigidez mecánica suficiente para soportar la carga y suprimir la vibración (vea la Figura 1). Si las tapas carecen de rigidez, puede que sea necesario utilizar tapas nuevas fabricadas con un material más grueso. En otros casos, se puede utilizar un inserto para reforzar la tapa existente.
