Answer: Tests have shown that this is a realistic option with 50x3 tube made of 1.4301, inner diameter 44.8 mm. These tubes are standard products and can be obtained from usual suppliers. The internal weld seam should be filed away before the bearing flange is inserted and the rough edges caused by sawing should also be deburred inside and out. The advantage of steel tubes is that they are insensitive to damage from rough-edged materials to be transported and, as a result, maintain their attractive appearance even after long periods of use.
