Stainless steel pins and bushes
Many chain conveyor applications involve moving products with a high moisture content such as bark, woodchip and peat. In such cases the internal surfaces of the selected conveyor chain can become rusty and corroded. This is particularly the case around the bearing surfaces of the pins and bushes of carbon steel conveyor chain.
Making a chain completely from stainless steel would solve this problem but the higher wear rate and significantly reduced tensile strength generally preclude this option. The FB answer is the development and manufacture of a carbon steel conveyor chain that can be constructed using stainless steel pins and bushes.
This unique approach, using a combination of components manufactured from different materials, enables FB to successfully overcome the difficulties of conveyor chain applications in a moisture ridden environment.
