Port cranes are mostly heavy slewing ring, such as: the combination of the three-row cylindrical roller slewing ring, which can withstand axial load and radial load, through the surface special processing technology with corrosion-resistant and durable.
FINE slewing bearings are used in various kinds of port crane equipment, among them gantry cranes are of particular interest for our products. Those cranes require slewing bearings with high load carrying capacity, higher reliability and safety. Our three-row roller large diameter slewing bearings have been applied here for decades and can fully meet such requirements.
Harbor mobile crane often use triple row roller slewing rings with an external diameter up to 4800mm to carry the high tilting moments.
