Product Overview
Our extensive line of excavator bucket wear parts is designed to address every wear challenge on your equipment. From standard chocky bars and wear bars to specialized carbide wear blocks and buttons, we provide a complete tool kit for reinforcing your buckets against the destructive forces of abrasion and impact.
Each component in this series is built using our proven bimetallic bonding technology. The hard wear-resistant surface (available in high-chrome iron or tungsten carbide) is metallurgicaly bonded to a mild steel base that can be easily welded, cut, and formed. This flexibility allows you to apply targeted protection exactly where it's needed most—on bucket lips, side cutters, heel shrouds, and wing protectors.
By utilizing a combination of different wear part shapes—such as buttons for point protection and chock bars for larger surface areas—you can create a customized armor system for your machinery. This holistic approach to wear protection ensures maximum machine availability and the lowest possible operating costs in mining, construction, and dredging operations.

Frequently Asked Questions (FAQ)
1. Which wear part shape should I use for my bucket?
Chocky bars are best for large flat or curved surfaces, while buttons are ideal for protecting corners and high-wear points. Wear bars provide excellent protection for long edges and lips.
2. Can I combine iron and carbide wear parts on the same bucket?
Yes, many customers use high-chrome iron for general protection and tungsten carbide buttons for the absolute highest wear points to balance cost and performance.
3. Are these parts compatible with all bucket sizes?
Absolutely. Our components are designed to be cut and positioned to fit everything from small utility buckets to the largest mining shovel buckets.
4. How do I ensure the best weld bond?
The mild steel base is easily weldable with standard low-hydrogen electrodes. We provide clear pre-heat and welding instructions for the best results.
5. Do you offer bulk kits with a mix of shapes?
Yes, we can provide customized wear kits that include a variety of bars, buttons, and blocks tailored to your specific fleet maintenance needs.
