Accuride Corp. subsidiary Gunite Corp. has developed a
lightweight fully cast brake drum as an alternative to
lightweight steel-shell drums.
Silver brake drum, produced at Gunites Rockford, Ill.,
plant, is designed to improve durability and performance at
reduced weight. It uses engineered design enhancements and
advanced metallurgy to achieve a 12.5-pound weight savings over
standard full-cast drums.
utilized a high-strength gray iron featuring improved
mechanical and structural material characteristics to build the
product, Accuride senior vice president of sales and marketing
Chuck Byrnes said.
The company said it
used the latest available casting technology and structural
simulation analysis tools combined with high-strength gray iron
to create an optimum mounting flange and wrap-around design
that contributes to overall weight reduction without
compromising design integrity.
"The new Gunite Silver
will (allow) additional payload, better fuel economy and lower
operating cost without sacrificing quality and dependability,"
The Silver weighs 99.5 pounds, about 11 percent less than
comparable brake drums, reducing a truck-trailer
combinations total weight by around 100 pounds, he
