Peripheral Grinder Bush

Peripheral grinders are used to sharpen steel bits on rock drills. Many mines still use this system although others use exchangeable drill bits.

This application receives no lubrication. A great deal of grit and dust gets into the bush, causing wear. Phosphor bronze bushes (OD 70 mm x ID 50 mm - 80 mm long)(OD 2.8" x ID 2" - 3.2" long) were not giving a satisfactory wear life so they were replaced with Vesconite.

Vesconite, not affected by lack of greasing or grit and dust, gives much longer life than the phosphor bronze. The Vesconite bushes have been fitted for two years without any problems being experienced.
