There are a number of ways to reduce stretch or elongation in a chain application. Some of the ways are listed below: *Improve the lubrication itself and the process of applying the lube to the chain ensuring the lube is penetrating the pin/bushing area. *Choose a chain that has a higher hardness of the chain’s bushings and pins. *Select a chain where tension is reduced in the bearing area (the pin/bushing area). Either reduce the tension on the chain or choose a chain with a larger pin diameter. *Increase the number of teeth on the sprocket that the chain engaged with. Should these techniques not yield the results you are looking for, consult with our engineering and sales departments.
