If wheels with ball or straight roller bearings are mounted in casters they should be equipped with a spanner bushing. If wheels with straight roller bearings are to rotate directly on a shaft (without a spanner bushing), then the shaft should be hardened and ground. For sizes other than shown, please contact us.
