50 o-ring roller chain is for drives where lubricating the roller chain is extremely difficult. Our #50 O-ring chain uses and o-ring between the two link plates, which seals lubricant into the "bearing" area of the chain. Another benefit is the o-ring keeps dust, dirt and other abrasive materials out. All o-ring roller chain should be lubricated periodically to prevent the o-ring from drying out and cracking.
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.
