Rockdrill Airleg Bush
The
topcap bush on a drill airleg is subjected to moisture and dirt. Conventionally
a steel bush is used. Although the life was reasonable, they represent a cost to
replace, with an additional hidden maintenance cost. A typical mine replaces
between 20 and 60 of these bushes a month.
Vesconite has proved a most successful replacement for top cap bushes.
Advantages of Vesconite in this application are:
- Much longer life
- Fewer replacements required
