The heavy construction machinery industry employs a variety of highly specialized mobile machines of different types, which continue to operate under the most severe conditions with low friction, without reducing load carrying capacity and minimal assembly time adjustment. Hensen bearing has successfully developed a series of products to solve the centrifugal force caused by vibration roller and high-frequency vibration, resulting in continuous heating of bearing. Early burn failure. This series of products have achieved success at home and abroad, for many well-known construction machinery manufacturers to provide supporting services.
