Thanks for writing to us. I'm afraid I couldn't find a roller like the one you show in your photos. I believe it is discontinued and no longer available. Is it just the wheels themselves that need to be replaced? If so, consider the 81-228 Nylon Concave Wheel, or the 81-226 or the 81-310 Repair Kits. If the housing itself is damaged, I'm afraid we cannot help.
