| In 1987 Hitachi Maxco,
Ltd. introduced the first premium line of
"solid bushing / solid roller" precision
roller chains. This series extended chain life by
replacing traditional curled bushings and rollers with
solid cold forged parts, produced in the state of the
art multi-station dies.
Today,
Hitachi is proud to introduce an enhanced version of
this superior product... Hitachi
SBR®. In
addition to sold round parts, wide waist link place
contours, high hardness carbonized alloy steel bearing
surfaces, this new series
boasts a unique dual surface coating for the pins and
bushings, as well as a redesigned heavy duty connecting
link.
