Is a manufacturer of large Roll Systems used in the textile industry. These rolls use a dual shell design, with channel welded to the outside of the inner shell. The channel between the shells transfers pumped oil during operation. MB offers the shells in both low-carbon and stainless steel, and manufactures them in sizes up to 6 feet OD, and up to 60 feet long. Both straightness and roundness tolerances are critical, typically ± 0.010″ over the full length.
