There is a Special Exhibit at MOBIO Tech Hall where exhibitors introduce "featured" products.
This month, SHINWA IRON WORKS displayed a full-size replica ring that is too large to display in the regular booth. Manufacturing of ultra-large ball bearing outer rings (φ2000 x width 200) made possible by its "technology of machining to a perfect circle". Visitors over 2 meters tall are requested to bend over, while those who are not so tall are requested to walk straight and go under the ring to view the exhibit.
