The UniqueTek 550 Primer Track Bearing has a 1.4″ extension that supports the primer bar better. This extended support prevents the primer bar from "drooping" and binding while its in the "out" position. Our Primer Track Bearing now features Nicklon™ is co-deposition of Electroless Nickel & PTFE (Teflon™). This yields a excellent lubricity, high wear resistance and very low coefficient of friction (0.10). This makes it the slickest primer track bearing there is!
