For sale is a set of Dura-bond CH-18 cam bearings
Dura-bond seamless, 100% machined surface design provides
the tightest tolerances in the industry. The centerless ground OD,
centerless bored ID results in wall variations of less than .0004 inch.
Dura-bond bimetal bearings are constructed of seamless steel tube with a thin
layer of lead based Babbitt material. Seamless construction makes
installation easy, eliminating breakage and bearing surface
interruptions. Lead based Babbitt provides ideal properties for nearly
all engine applications. Babbitt's superior embedability,
conformability, and anti-seizure characteristics have proven to reduce engine
failures that harder bearing materials can cause.
