Wear tires
Columbia wear tires are cast of our J series high chromium alloy iron, fully heat treated. The bore is accurately tool-machined for excellent fit. We can provide standard bore wear tires, as well as custom bore tires to the diameter you specify. In either case, you are ensured the right fit and prompt delivery.
Weartrack segments
Our J series of high chromium alloy irons provides excellent wear resistance for weartrack segments.
Outer wall castings and ledge covers
These parts are cast from our long wearing high chromium iron alloy. Both parts are designed to bolt through the pulverizer wall, as well as to each other, giving solid attachment.
Pivot blocks and rolls
We also offer roll pivot blocks and pivot rolls so you can rebuild with all-Columbia wear parts.
