Each idler is precision machined to house special high impact low wear bimetallic bushings.
Our quality procedures
1. When raw material come inside our factory,we need to test the material composition first.
2. We need to analyze the composition of the first furnace of the steel liquid every day.
3. After several pcs of parts are heattreated, we need to check the hardness before all to be done to guarantee the hardness.
4. Our inspectors will check the sizes when parts are being machined and parts are being assembled.
