For sale is a set of Dura-bond CH-25 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.
