  Se realiza un estudio tribológico de aceites y grasas lubricantes en la "Máquina Shell de 4 Bolas". Se ofrecen resultados para los distintos aceites y grasas, variando las condiciones de prueba para conocer el comportamiento de los valores de desgaste a bajas cargas según el método; se busca hasta qué carga la película de lubricante se mantiene sobre las superficies metálicas de las bolas (sin que ocurra el agripado), y se analiza a qué carga ocurre la soldadura. Con estos ensayos se logra demostrar el comportamiento de distintas formulaciones de aceites y grasas.

  Lubricating formulations and lubricants have been slanted heavily toward protecting gear concentrated contacts fromgalling and wear. Much performance differentiation of these lubricantshas been dependent on highly accelerated standardized laboratory testing. The performance effects of fully and partially additized lubricants were studied, using standard assay to lubricating oils for ball machine benches. The test results indicate that significant detrimental effects of wear and fatigue in relation to life performance can occur with some additized lubricant formulations.The best formulation to withstand wear and increased load capacity for each lubricating oil was studied and selected, depending on how the mechanism would be used.
