If precision roller chain is in the room temperature environment, it basically does not need too much attention, but the key is that when it meets the high temperature environment, the application of precision roller chain must be paid more attention and more problems need to be considered.

Due to different manufacturing processes, the coefficient of thermal expansion of the precision roller chain is also different, so when different materials are welded together, thermal fatigue is likely to occur. Especially when the ambient temperature exceeds 400 ° C, the intermittent caused by expansion between the precision roller chain should also be fully considered to reduce.

Compared to ordinary chains, precision roller chain performance is relatively stable, but high temperatures can affect its lubrication performance. Because in order to avoid the occurrence of adverse phenomena, the precision roller chain should take corresponding protective measures to improve the high temperature resistance.

When used at ultra-high temperature above 400℃, because the strength of the precision roller chain will gradually decrease with the increase of temperature, the use of friction will be limited, depending on the temperature and ambient temperature, otherwise the service life of the precision roller chain will be affected.

In general, the precision roller chain is resistant to high temperatures, so it will not affect its service life at 400 ° C. However, due to the manufacturing process used by different manufacturers, their high temperature tolerance is also different.
