Our paper converting customer found that they were replacing their metal brake drum on an annual basis. Closer examination revealed that the excessive wear pattern matched the spacing of the rivet holes.
It was concluded that in this application and environment, some aggressive particles worked in the path of the rivet holes causing unacceptable, uneven wear.
We came up with undrilled blocks in the correct arc and thickness. Next, we bonded this lining to our customers brake shoes, eliminating the need for rivets. Our customer cleaned up the worn drum and has been running smoothly since.
If you have a brake wear problem, let us know.
