Specifically designed with sealed-in lubrication, makes KMC sealed chain work to its optimum life. Superior alloy steel is used and heat-treated to provide best performance in strength. In addition, specially formulated grease contained by using a durable ring in between solid bushing and hardened pin, keeps constant lubrication and eliminates friction during operation. Least wear results in least chain stretch and prolongs its service life.
