Lube Free Roller Chain<br />

Marathon Series<br />

Our MA-Series Marathon Maintenance Free Chain<br />

requires no further lubrication and may provide up<br />

to 35 times greater life as <strong>com</strong>paired to standard<br />

roller chains as well as up to 5 times greater service<br />

life with other maintenance free chains. The<br />

ultra high strength oil impregnated sintered bushings<br />

fit tightly to side plates sealing the chain from<br />

possible contaminants that can wear pins and<br />

bushings. The pins are specially hardened and<br />

coated to help provide the extended life. These<br />

chains fit standard sprockets. A stainless version<br />

is also available.<br />
