Cast Iron Bearing Pulley
This kind of pulley was produced by
spheroidal graphite AS 1831 Grade
500.7, also called as ductile iron
ASTM A536 70-50-05, or 80-55-06.
Most of pulley should be assembled with
pulley, shaft, spring and bearing. The
pulley could be produced by automatic
molding line or shell molding casting
process. The shaft should be machined
directly by high tensile steel bars.
The followings are some photos for the
cast iron pulley that our foundry
produced in the past.
