This chain is manufactured with a o-ring between the pin and roller to hold in lubrication for longer life. Also helps keep dirt and abrasive material out.
Maintenance and lubrication is crucial in the overall performance and life span of roller chain. Proper lubrication will reduce abrasion, chain wear, friction, noise and keep chains running cooler at higher RPM's. You can download the Nitro Roller Chain Care below.
