I second the recommendation on Castor City. Also, you will probably end up with Polyolefin for your spec instead of Polyurethane. It depends on the load and how long the load stays in one place. If the cabinets are heavy, you probably won't be able to size Polyurethane to keep them from flat spotting. How heavy is heavy and will they sit still for weeks or months? The point is that places like Castor City will give you very good prices and the right castor for the job.
