Fullerene C60 has been attracting attention as a kind of lubricant. In this experiment, four kinds of lubricants oil with different concentrations of fullerene were prepared for the purpose of extending the service life of bicycles, for which demand has been increasing in recent years. These lubricants were added to the contact area between the pin and the roller of the chain, and then durability tests were conducted using a chain testing machine to confirm the effect of fullerene as an additive. The amount of movement of the sprocket on the driven side of the linear guide was measured with a displacement sensor, and the amount of elongation was measured. The results showed that the amount of elongation decreased with the use of fullerene lubricant, and the amount of elongation was the lowest when the fullerene concentration was 2000 ppm. It was also found that there was no significant difference in the amount of elongation between 100 ppm and 1000 ppm.
